PI aerogel preparation shrinkage and cracking
Sorun Belirtisi
PI aerogel shrinks severely after supercritical drying or freeze drying
Neden Analizi
The gel network strength is insufficient to withstand capillary forces during drying; solvent exchange insufficient
Çözüm
Strengthen the gel network (increase crosslinking or polymerization concentration); fully exchange solvent; optimize drying conditions
Temel Çıkarım
The core of PI aerogel preparation is protecting the nanoporous structure
