Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <sec id="mame201200337-sec-0001" sec-type="section"> <p>The direct electrospinning of a non‐derivatized cellulose (Cs)–chitosan (Ch) composite nanofiber is described for the first time. Either of two cellulose preparations from different sources, i.e., cotton (Cs^C) or bamboo (Cs^B), is fabricated into composite electrospun non‐woven fabrics (ESNWs) with Ch using the trifluoroacetic acid–acetic acid mixed solvent. The total concentration of Cs + Ch in the mixed solvent is fixed at 4.0 wt.‐% with various Cs/Ch weight ratios of 8:2, 5:5 (Figure shows Cs^B/Ch‐ESNW), and 2:8, which are fabricated into fine fibers in the Cs/Ch‐ESNWs having average diameters mostly &lt;100 nm. The treatment of the composite fibers with an alkaline–alcohol solution produces the water‐resistant ESNWs, which can retain their fine fibrous network in aqueous environments.<inline-graphic xlink:href="ark:/27927/pgg3j5r6jfc" content-type="mame201200337-gra-0001" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </sec> </abstract>
