Abstract

To enhance the mechanical properties of cellulose fibers for high-strength applications, this study explores the incorporation of amine-modified graphene (G-NH₂) into the cellulose/4-(ω-(methylimidazole)hexyloxy)-4'-(cyano)-biphenyl(CBP6)/ionic liquid system. By adjusting experimental temperature, time, and G-NH₂ composition, a cellulose/CBP6/G-NH₂/ionic liquid liquid crystal solution was successfully developed. The liquid crystal properties of the solution were characterized using polarizing optical microscopy and differential scanning calorimetry, among other techniques. Results indicated that the introduction of G-NH₂ altered the liquid crystal texture and introduced novel liquid crystal phenomena. Regenerated cellulose fibers from the cellulose/CBP6/G-NH₂ system exhibited a breaking strength of 3.82 cN/dtex and an elongation at break of 8.1%, prepared with 6 wt% cellulose, 3 wt% CBP6, and 0.2 wt% G-NH₂, through liquid crystal spinning. The structural and mechanical properties of these fibers were thoroughly characterized. This study not only presents a new strategy for producing high-performance regenerated cellulose fibers but also offers valuable insights for the development of cellulose-based composites.

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.
