Manufacturing methods for aerogel and aerogel composite material

Abstract

This application relates to a method for manufacturing an aerogel. The method includes the following steps: First, a liquid is provided. Then, a plurality of microbubbles are generated within the liquid. Next, the liquid is solidified to create a porous solid model. Then, under sublimation conditions of the liquid, a pair of polyxylene materials are deposited onto the porous solid model to obtain a pair of polyxylene aerogels. In addition to the aforementioned method for manufacturing the aerogel, this application also provides a method for manufacturing an aerogel composite material.
