Abstract

Aerogels have the potential for usage in many daily and high-tech aerospace applications. Silica aerogels are fragile, while organic aerogels are much tougher, but they are both generally synthesized using toxic solvents. Biodegradable aerogels, if they possess similar properties as polymer aerogels, could be widely utilized in many aerospace applications and offer environmental benefits. In this work, potato starch aerogels were systematically studied. The potato starch concentration, the amount of plasticizer (glycerol), and an acid source (acetic acid) were varied. The relationship of the precursors on potato starch aerogel's properties, such as density, shrinkage, porosity, BET surface area, mechanical properties, and thermal conductivities, were researched. The resulting potato starch aerogels possess suitable density, Young's modulus, and thermal conductivity for use in many aerospace applications.

航空航天用马铃薯淀粉气凝胶合成参数的变化。
气凝胶在许多日常和高科技航空航天应用中具有潜在的用途。二氧化硅气凝胶是脆弱的,而有机气凝胶更坚韧,但它们通常都是使用有毒溶剂合成的。生物可降解气凝胶,如果它们具有与聚合物气凝胶相似的特性,可以广泛应用于许多航空航天应用并提供环境效益。本文对马铃薯淀粉气凝胶进行了系统的研究。马铃薯淀粉的浓度、增塑剂(甘油)的用量和酸源(乙酸)是不同的。研究了前驱体对马铃薯淀粉气凝胶密度、收缩率、孔隙率、BET比表面积、力学性能和导热系数等性能的影响。所得到的马铃薯淀粉气凝胶具有合适的密度、杨氏模量和导热性,可用于许多航空航天应用。

期刊介绍: The journal Gels (ISSN 2310-2861) is an international, open access journal on physical (supramolecular) and chemical gel-based materials. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the maximum length of the papers, and full experimental details must be provided so that the results can be reproduced. Short communications, full research papers and review papers are accepted formats for the preparation of the manuscripts. Gels aims to serve as a reference journal with a focus on gel materials for researchers working in both academia and industry. Therefore, papers demonstrating practical applications of these materials are particularly welcome. Occasionally, invited contributions (i.e., original research and review articles) on emerging issues and high-tech applications of gels are published as special issues.
