In this work, a successful method of creating high-performance TPV using a ternary blend of poly(methyl methacrylate) modified natural rubber (MGNR), poly(vinylidene fluoride) (PVDF), and fluorocarbon elastomer (FKM) was employed. Combining NR known for its exceptional rubber elasticity and resilience, with fluoropolymers, known for their exceptional chemical resistance and thermal stability, resulted in materials with a synergistic blend of properties. The developed PVDF/FKM/MGNR blend showed higher elasticity, tensile strength, and elongation at break than PVDF/FKM and PVDF/MGNR blends because the ternary blend had greatly improved phase morphology and compatibility between the three phases. The domain size in the ternary blend was smaller than 150 nm. The ternary blends also exhibited excellent thermal properties, where melting and crystallization temperatures were reduced significantly with MGNR due to possible dipole-dipole interactions. At the same time, the oil resistance and shape memory behavior of PVDF/FKM/MGNR were improved at an appropriate blend ratio. The ternary TPVs demonstrated good shape fixities (90–100 %) and shape recoveries (70–80 %). This research offers valuable insights into the design of high-performance thermoplastic elastomers based on natural rubber, which have excellent mechanical properties, solvent resistance, and potential for intelligent and lightweight application.</div></div>","PeriodicalId":20628,"journal":{"name":"Polymer Testing","volume":"140 ","pages":"Article 108594"},"PeriodicalIF":5.0,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142357565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Filament bonding is usually associated with material temperature and can be observed between layers (interlayer) and in the same layer (intralayer). The latter is not much explored in the literature and is rarely studied when the material extrusion must be resumed to complete a layer filling. A non-continuous tool path is usually found in filling complex part geometries with a raster strategy, where the area to be filled is divided into more than one continuous raster segment (CRS). The contact between the filaments of two adjacent CRSs (at 100 % density), defined as resumed contact (RC) for simplicity, can be affected by a weak bonding effect. This work aimed to experimentally study this effect by varying the time taken to resume printing, causing the temperature to drop at the RC, and measuring the influence on bonding strength. The bead width at the resumed extrusion was also analyzed. The results show that the influence of time taken to resume printing (contact temperature) on bonding strength was not significant for the part geometry tested and printer used. Notwithstanding, material failure under tensile load always occurred in the RC region. The results also showed some bead width variation due to under extrusion at the start of the extrusion, which can reduce the contact area. Therefore, the weak intralayer bonding at the RC is a fact, and it is affected, among others, by a combination of cold bonding and any contact area reduction due to under extrusion at the start of the extrusion. This issue must be carefully considered when printing an end-use part where the material strength is paramount.</div></div>","PeriodicalId":20628,"journal":{"name":"Polymer Testing","volume":"140 ","pages":"Article 108595"},"PeriodicalIF":5.0,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142328049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, the common differential scanning calorimeter (DSC), polarized optical microscopy (POM), atomic force microscopy (AFM) and FSC were performed to investigate the crystallization and melting behavior of P4HB. The results indicated that melt crystallization facilitated the formation of fragmented crystals rather than complete spherulites. Furthermore, the P4HB exhibited a broad crystallization temperature range from −19 °C to 49 °C, and the crystallization and melting of P4HB was notably affected by the temperature, in addition to the heating or cooling rates. The higher crystallization temperature and lower cooling rates facilitated the formation of well-developed crystals. Remarkably, the P4HB is found to be unable to crystallize at heating or cooling rates exceeding 6 K/s. Moreover, double melting peaks could be discerned at moderate isothermal crystallization temperature exhibiting faster crystallization rate.

Experimentally observing the migration process is challenging and time-consuming. This study employed molecular dynamics (MD) methods to simulate a molecular model of the NEPE propellant/liner interface layer, enabling the prediction of component migration behavior. We visualized the migration process of all propellant components and studied the interface layer components' migration patterns, diffusion coefficients, and concentration gradient distributions. The contents of migrated components of the propellant and liner at different accelerated aging times at 70 °C were determined using high-performance liquid chromatography (HPLC), and the simulation patterns were compared with experimental observations. The results indicate that the migrated components in the propellant mainly consist of nitrate esters (Nitroglycerin, abbreviated as NG, and Butanetriol Trinitrate, abbreviated as BTTN), stabilizers (NMethylnitroaniline, abbreviated as MNA, and 2-Nitrodiphenylamine, abbreviated as 2-NDPA), and solid component (Hexahydro-1,3,5-trinitro-1,3,5-triazine, abbreviated as RDX). The migration process is primarily dominated by the substantial migration of nitrate esters, which is a key factor contributing to the degradation of propellant performance during storage. The migration process can be divided into three stages: swift migration, steady slow migration, and migration equilibrium. The diffusion coefficients are ranked from most significant to most minor as NG &gt; BTTN &gt; RDX &gt; MNA &gt; 2-NDPA. Three migration stages consistent with the simulation process were observed using HPLC, and the migration behavior of nitrate esters aligned with simulation patterns. Our designed full-component model can qualitatively predict component migration behavior. Additionally, a faster diffusion coefficient does not necessarily lead to a greater amount of migration. We employed MD simulations combined with density functional theory (DFT) calculations to explain this phenomenon and found that intermolecular interactions may influence the diffusion coefficient. At the same time, the migration amount is highly correlated with molecular polarity. Therefore, increasing the molecular polarity difference between easily migrating components and liner materials is a beneficial strategy for slowing the migration process and enhancing the storage safety of propellants.</div></div>","PeriodicalId":20628,"journal":{"name":"Polymer Testing","volume":"140 ","pages":"Article 108583"},"PeriodicalIF":5.0,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0142941824002605/pdfft?md5=37f73a6b1617f87a1f992a25c91c6644&pid=1-s2.0-S0142941824002605-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142311991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
