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.
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.
