Transforming jute waste into high-performance biodegradable polyurethane bionanocomposites
Bionanocomposites have been synthesized by reinforcing cellulose nanofibers (CNFs) into lignopolyol based polyurethane (PU). Both lignin and cellulose nanofibers were isolated synchronously from waste discarded jute bags. The effect of cellulose nanofiller (concentration ranging from 0 to 15 wt.%) on mechanical properties, thermal stability and hydrolytic degradation of the synthesized PU/CNF nanocomposites was also examined both experimentally and statistically. The mechanical and thermal properties were studied using thermal gravimetric analysis (TGA-DTG) and tensile testing. The hydrolytic degradation of PU nanocomposites was studied in phosphate buffer saline (PBS) for 8 weeks. Multivariate analysis of variance (MANOVA) is utilized to analyze the effect of cellulose nanofiller concentration. The 10% addition of CNFs resulted in more than 600 ± 10% and 181% ± 8 increase in tensile strength and hydrolytic degradation. The MANOVA results demonstrated a significant correlation between cellulose nanofiller concentration and the mechanical properties, thermal stability, and hydrolytic stability of the nanocomposites.
期刊介绍：
Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
