Ultra-porous Aerogel contained Flexible PET Nonwovens for Acoustic and Thermal Insulation

초록

Ultra poroous Aerogel contained PET nonwovens were prepared at ambient pressure and their acoustic and thermal insulation properties were characterized. Two methods were selected for the preparation of PET/Aerogel composite. Method I was a direct gelation of silica on PET, Where PET non-woven fabric was dipped and swelled in TEOS/ethanol mixture and pH of reaction media was controlled to 2.5 using HCl to promote hydorlysis.
