PI aerogel preparation shrinkage and cracking
문제 현상
PI aerogel shrinks severely after supercritical drying or freeze drying
원인 분석
The gel network strength is insufficient to withstand capillary forces during drying; solvent exchange insufficient
해결 방법
Strengthen the gel network (increase crosslinking or polymerization concentration); fully exchange solvent; optimize drying conditions
핵심 요약
The core of PI aerogel preparation is protecting the nanoporous structure
