Stress and Strain of Plant Polysaccharides Aerogels and Their Effects on Mechanical Properties

Abstract In order to verify the mechanical properties of plant polysaccharides aerogels, the polysaccharide aerogels were prepared by freeze-drying method. The aerogels were screened by raw material selection and mass ratio, and their mechanical properties were tested. The experimental results show that with the increase of starch content, the compression modulus increases gradually, and the elasticity decreases linearly with the increase of starch content. The main effect on the mechanical properties is that after the addition of polysaccharide macromolecules, they are entangled with KGM and gelatin skeleton molecules. The increase of concentration increases the interaction sites, and the intermolecular force increases.
