Abstract
Cellulose nanofibers (CNF) were isolated from raw cotton fibers via 2, 2, 6, 6-tetramethylpiperidine-1-oxyl (TEMPO) oxidation process. The isolated CNF were morphologically characterized using Field Emission Scanning Electron Microscopy (FESEM) and Transmission Electron Microscopy (TEM). Entangled fibrous morphology with diameter in nano regime (15–20 nm) has been observed for the isolated nanofibers. X-ray diffraction (XRD) analysis confirms the high crystallinity of the isolated CNF. Further, the isolated CNF was used to reinforce natural rubber (NR) latex films. The crystallographic, morphological, and spectroscopic analysis of the NR/CNF nanocomposites was carried out. A strong interaction between the CNF and NR matrix has been identified and which reflects in the thermal stability and swelling behavior of NR/CNF nanocomposite films in toluene. The uniform dispersion and tangling effect of CNF along with strong NR-CNF interaction restrict the uptake of solvent through NR matrix.
期刊介绍：
Polymers from Renewable Resources, launched in 2010, publishes leading peer reviewed research that is focused on the development of renewable polymers and their application in the production of industrial, consumer, and medical products. The progressive decline of fossil resources, together with the ongoing increases in oil prices, has initiated an increase in the search for alternatives based on renewable resources for the production of energy. The prevalence of petroleum and carbon based chemistry for the production of organic chemical goods has generated a variety of initiatives aimed at replacing fossil sources with renewable counterparts. In particular, major efforts are being conducted in polymer science and technology to prepare macromolecular materials based on renewable resources. Also gaining momentum is the utilisation of vegetable biomass either by the separation of its components and their development or after suitable chemical modification. This journal is a valuable addition to academic, research and industrial libraries, research institutions dealing with the use of natural resources and materials science and industrial laboratories concerned with polymer science.
