Science Daily  October 3, 2022 Researchers in Hong Kong have developed new type of polymer aerogel material involving self-assembled 3D networks of aramid nanofiber composites with high nodal connectivity and strong crosslinking between fibrils. Theoretical simulations of 3D networks revealed that these features at fibrillar joints may lead to an enhancement of macroscopic mechanical properties by orders of magnitude even with a constant level of solid content. They verified that polymeric aerogels achieved both high specific tensile modulus and fracture energy which are advantageous for diverse structural applications. According to the researchers the fabrication process is simple, the material can […]
