ABSTRACT Hemp woody core (HWC) that is a by-product of hemp industry was subjected to pre-treatment with alkali (mercerisation) and further functionalisation with epoxidised soybean oil (ESO) or (3-aminopropyl)triethoxysilane (APS). Mercerisation resulted in more developed surface area and rearrangement of fibrils into denser packing. FTIR spectroscopy analysis revealed the presence of hydrogen bonds of HWC with modifier in case of ESO application as well as hydrogen and Si-O-C covalent bonds in case of APS application. Two types of Si-containing epoxyurethanes were filled with 60% of HWC with different surface modification: the first polymer contained diglycidyl ether of bisphenol-A (DGEBA), while the second one contained ESO as an epoxy component. The investigation of the surface properties of composites found that the ones based on ESO epoxyurethane were more hydrophobic than their respective counterparts. Hydrophilicity was reduced by functionalisation of HWC providing a contact angle augment from 54°for DGEBA-containing sample with raw HWC to 86° for the one with oil modified HWC. The results of water uptake test showed that regardless of the matrix the composites reinforced with functionalised HWC exhibited about 40% less gain in weight at the saturation level than their analogues reinforced with untreated or alkali treated HWC.

ABSTRACT Several research articles in the field of nanocomposite have revealed that organic fillers can be used as reinforcing agents for plastic materials in hybrid material production. Advancement in multifunctional materials is anticipated to grow with the advent of lightweight, low-cost, and sustainable materials with improved mechanical, fire retardancy, water resistance, and higher barrier properties. As reported in the literature, these performance properties could be obtained by reinforcing nanoclay/organic filler in polymeric matrices. In this report, the pretreatment techniques for overcoming the challenges of hybrid composite production are discussed in detail. The bonding mechanisms between the nanoclay and plastic materials are explained. The study gives an overview of the recent progress on multifunctional hybrid materials made using nanoclay/organic particulate fillers as reinforcements for polymer matrices intended for use in the automotive, building, and construction industries.

Pretreatment using O2 plasma is a commonly used method today to increase the surface activity of CFs and enable more functional groups to be grafted onto them. Although the oxidation treatment of the CF surface is considered a key procedure for further grafting with functional groups, few researchers have investigated how the oxidation treatment influences the grafting processes. In this paper, the effects of the degree of oxidation on the grafting of amino functional groups onto CFs were experimentally investigated. The experiment showed that the oxidation process developed in steps including initial oxidation, saturation oxidation, and peroxidation. The results demonstrated that the degree of oxidation was positively correlated with the grafting efficiency within a certain range. Furthermore, the groups (unsaturated C, C-OH, and O=C-OH) produced after oxidation determined the results of grafting with amino (C-N, C-NH2, and O=C-NH2) groups. When the O2 plasma treatment time was increased from 0 min to 3 min, the IFSS of CF@HA increased by 1.07 times and the flexural strength of CFRP increased by 1.26 times. This work proves that the ammonia grafting of CF can be controlled by adjusting its earlier oxidation process.

ABSTRACT In this work, epoxy (EP) resin composites with multi-scale reinforcements were prepared by hand lay-up and hot-pressing. The epoxy was reinforced with basalt fibers (BF) modified with a silane coupling agent (KH560). Carboxylated multi-walled carbon nanotubes (CNTs) were also grafted onto the surface of the modified BF using an impregnation method to achieve BF/CNTs multi-scale reinforcement. Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) showed that KH560 was successfully grafted onto the BF surface. Scanning electron microscopy (SEM), indicated a better resin adhesion on the BF and thus a stronger interfacial interaction in the BF/CNTs-reinforced composite. It was observed that the mass fraction of KH560 was a significant parameter in achieving desirable CNT immobilization and mechanical properties of the composites. At an optimal mass fraction of KH560 (5%), the tensile, flexural, and interlaminar shear strength (ILSS) of the modified composite (BF-5%KH560-CNT/EP) increased by 12.5%, 20.9%, and 25.5% respectively compared with the BF-washed/EP composite due to more efficient load transfer. In addition, compared with BF-washed/EP, the decomposition onset temperature of BF-5%KH560-CNT/EP increased from 387°C to 396°C, the maximum decomposition rate temperature increased from 400°C to 408°C, and the residual weight increased by 5.8%.

ABSTRACT PLA/HAP composites have attracted significant attention in material science, especially in the field of biomaterials. However, these composites have suffered from unfavorable interface interactions between PLA and HAP interfaces, which limits the applications . In this study, we aimed to improve the interface interactions of PLA/HAP composite by modifying the HAP surface. For this purpose, HAP particles were functionalized with three different silane modifying agents, including (3-Aminopropyl)trimethoxysilane (AMMO), (3-glycidyloxypropyl)trimethoxysilane (GLYMO) and (3-triethoxysilyl)propylsuccinic anhydride (GF-20). The obtained modified HAP (m-HAP) were used to prepare PLA/m-HAP. Interface interactions of composites were characterized by Fourier transform infrared spectrophotometer (FT-IR) and differential scanning calorimetry (DSC). In addition, Vickers hardness tests were performed to reveal the effect of silane modifying agents on hardness before and after the in vitro degradation test. GRAPHICAL ABSTRACT

ABSTRACT The ability of composite cement materials to resist erosion by chloride ions is a critical factor in evaluating their dependability. This study aims to examine the influence of graphene oxide on the transportation of water molecules and chloride ions in modified cement composites. Molecular dynamics analysis suggests that graphene oxide can effectively bond to the substrate of hydrated calcium silicate gel pores, which forms a stronger confined fluid zone under the action of electrostatic interactions and van der Waals forces. Graphene oxide has negatively charged oxygen functional groups on its surface, and within a certain size range, it becomes more effective at restricting the penetration of water molecules and chloride ions. In addition, chloride solution immersion experiments were performed on graphene oxide modified cement mortar. The results demonstrated that a small quantity of graphene oxide can significantly improve the resistance of modified cement mortar to chloride ion erosion, whereas excessive amounts are detrimental, which aligns with the simulation results. It is hoped that this study will provide valuable insights into the use of graphene oxide nanoparticles in the corrosion protection of cement composites. GRAPHICAL ABSTRACT

ABSTRACT According to EURO IV and EURO V, benzene in gasoline should not exceed 1 volume%, to prevent environmental pollution and health risks; hence benzene must be removed from pyrolysis gasoline (octane booster), before blending with gasoline. Polyvinyl alcohol (PVA) based membranes are quite effective for pervaporative separation of hydrocarbon mixtures. The main objective of this work is to fabricate insitu Ag/PVA nanocomposite membranes, using simple solution casting approach, for pervaporative separation of benzene from model pyrolysis gasoline (mixture of benzene/1-octene). Debenzenation of pyrolysis gasoline using PVA-based polymeric membranes was not reported by earlier researchers. The impact of incorporation of nano-Ag in the PVA matrix, on the pervaporative performance of the PVA membrane towards benzene, based on the swelling coefficient, fractional free volume, total flux, separation factor and activation energy, is the novelty of this study. Scanning Electron Microscopy, Transmission Electron Microscopy, mechanical strength, UV-Vis spectroscopy, Fourier Transform Infrared Spectroscopy were used to characterize all the fabricated membranes. The most suitable composite membrane for the intended purpose was identified. The maximum flux and highest separation factor of the said membrane are 4.05 kg/m2/h and 5.51 respectively at 343K operating temperature and 1 mm Hg downstream pressure. GRAPHICAL ABSTRACT

ABSTRACT Zirconia-toughened alumina (ZTA)-reinforced high-chromium cast iron (HCCI) composite materials were prepared using pressureless sintering method, and the effects of the type (titanium (Ti), nickel (Ni)) and content (10%, 12%) of active additives on the wettability and wear resistance were systematically studied. Result showed that the additive can enhance the wettability capacity between ZTA/HCCI composites interface, especially Ti, which reacted the chemical reaction and formed a transition layer in metallurgical combination. When the content of the Ti additive was 10%, the Brinell hardness (HB) of ZTA/HCCI composite was 573.1 N/mm2 at room temperature, and the wear-resistant properties were more than 3.8 times of pure HCCI. After thermal treatment, the HB and wear resistance of 10% Ti-ZTA/HCCI composites increased significantly which could reach 629.8 N/mm2 and were more than 4.3 times of the pure HCCI, respectively.
