Scalable Liquid‐Phase Exfoliation of h‐BN for Solar‐Reflective and Thermally Stable Polymer Aerogels
High‐pressure homogenization exfoliates hexagonal boron nitride (h‐BN) into stable nanosheets, which are incorporated into PVA, CMC, and HEC matrices to form lightweight composite aerogels. Tuning h‐BN loading (0–50 wt%) transforms the structure from porous to densely packed, tailoring optical, thermal, and mechanical properties. An optimized PVA/20 wt%
