摘要

本综述主要介绍最近开发的各种壳聚糖基纳米纤维(膜、贴片、垫和支架),这些纳米纤维利用乳液和同轴电纺丝技术设计成核心和外壳结构。壳聚糖是从天然资源中提取的一种前景广阔的多糖,具有多种应用潜力,包括旨在促进可持续发展的纳米纤维生产。与单轴纤维相比,基于壳聚糖的芯/壳纳米纤维具有药物封装和持续释放能力等吸引人的特点,而且效率更高。本文总结了核/壳壳聚糖基纳米纤维的制备方法,包括共纺剂和各种纺丝参数,如纺丝电压、针头尺寸、纺丝流速、针尖到收集器的距离、温度和湿度。综述还探讨了纺织品、医用敷料、药物释放系统、过滤膜和食品包装等各个领域的最新应用。文章重点介绍了目前通过电纺丝技术生产的基于壳聚糖的核/壳纳米纤维所取得的进展。对近期文献中提出的创新见解以及与这些可持续材料相关的挑战进行了深入研究,为该领域做出了宝贵贡献。

Developments of Core/Shell Chitosan-Based Nanofibers by Electrospinning Techniques: A Review
This review is focused on the recent development of various chitosan-based nanofibers (membranes, patches, mats, and scaffolds) that have been designed into core and shell structures using emulsion and coaxial electrospinning techniques. Chitosan, a promising polysaccharide derived from natural sources, holds potential for diverse applications, including nanofiber production, aimed at fostering sustainability. Core/shell chitosan-based nanofibers offer appealing features, including drug encapsulation and sustained release capabilities, with a higher efficiency than uniaxial fibers. The fabrication of core/shell chitosan-based nanofibers, including the co-spinning agents and various spinning parameters, such as spinning voltage, needle size, spinning flow rate, distance from needle tip to collector, temperature, and humidity, is summarized in this work. The review also explores updated applications in various fields, such as textiles, medical dressings, drug release systems, filtration membranes, and food packaging. It highlights the current advancements in core/shell chitosan-based nanofibers produced via electrospinning techniques. The innovative insights presented in the recent literature and the challenges associated with these sustainable materials are thoroughly examined, offering valuable contributions to the field.

期刊介绍: Fibers (ISSN 2079-6439) is a peer-reviewed scientific journal that publishes original articles, critical reviews, research notes and short communications on the materials science and all other empirical and theoretical studies of fibers, providing a forum for integrating fiber research across many disciplines. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. The following topics are relevant and within the scope of this journal: -textile fibers -natural fibers and biological microfibrils -metallic fibers -optic fibers -carbon fibers -silicon carbide fibers -fiberglass -mineral fibers -cellulose fibers -polymer fibers -microfibers, nanofibers and nanotubes -new processing methods for fibers -chemistry of fiber materials -physical properties of fibers -exposure to and toxicology of fibers -biokinetics of fibers -the diversity of fiber origins
