Abstract

Natural cellulose fibers have a unique hierarchical structure, starting from nanofibers, to microfiber bundles, and consequent to large scale fibers. This work wants to utilize this characteristic to tailor the surface morphology of plant-based fabrics in situ, avoiding complex separate washing process, and explore their functional applications. Specifically, ramie fabric was moderately oxidated using the 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)/NaClO₂/NaClO system. The scanning electron microscopy results show that a large number of cellulose micro-nanofibers can protrude from the fiber surface on the TEMPO-mediated oxidized ramie fabric (TORF) by controlling the reagent additions, which enlarges the specific surface area of the fabric. Subsequently, the crystal structure, chemical structure, carboxylate content and mechanical properties of the fabrics with different degrees of oxidation were determined in detail. In addition, the TORF was successfully modified by carbon nanotubes (CNTs) through simple physical adsorption. The electrical conductivity of the CNT-modified TORF increases with the oxidation degree of the fabric. Moreover, it shows application potential in fields such as electric heating. Based on the natural hierarchical structure, this work provides new ideas for the surface structure tailoring of natural plant fabrics and fibers, and also provides a platform for fabric functionalization.

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.
