摘要
淀粉是一种可再生的天然高分子,具有生物相容性好、可生物降解、无毒等优点,而水凝胶是具有吸水、保水性能的亲水聚合物网络。本文对近5年来淀粉基水凝胶的研究成果进行了归纳总结,以期为科研工作者提供淀粉基水凝胶的最新研究进展。文章分为如下部分:第一部分介绍了淀粉基水凝胶的研究背景;第二部分从淀粉基水凝胶的组成、形成原理、环境响应性等方面进行归纳总结;第三部分重点介绍了淀粉基水凝胶在水体净化、药物缓释、3D打印、农业和再生医学方面的应用。由此可知,目前淀粉基水凝胶在传感器、光电材料等方面的应用研究较少,同时其性能还不能够完全满足实际需求,因此科研工作者需进一步研究淀粉基水凝胶的结构与性能相互作用规律,完善淀粉基水凝胶的制备策略,拓展淀粉基水凝胶的应用范围,同时快速将其商品化及市场化,以产生巨大的经济效益与环境效益。
Starch is a kind of renewable natural macromolecule,possessing the advantages of good biocompatibility,biodegradation and non-toxicity,while hydrogel is a hydrophilic polymer network with the properties of water absorption and retention.In order to facilitate the researchers to understand the latest research progress of starch-based hydrogels,this paper summarized the research achievements of starch-based hydrogels in the past five years.This paper was divided into the following sections:The first part introduced the research background of starch-based hydrogels.The second part summarizes properties,formation principle and environmental responsiveness of starch-based hydrogels.The third part focused on the application of starch-based hydrogels in water purification,drug sustained release,3D printing,agriculture and regenerative medicine.According to the facts mentioned above,there were few studies on the applications of starch-based hydrogels in self-healing materials and optoelectronic materials,and at the same time their performance cannot fully meet actual needs.Therefore,researchers needed to further study the interaction between the function and structure of starch-based hydrogel,improved its preparation strategy,expanded its application scope and quickly made it commercialization and marketization to bring huge economic and environmental benefits.
