기계적 강도가 향상을 위한 폴리비닐피롤리돈과 가교된 에어로겔

초록

Conventional silica-based aerogels are promising materials. ? But they have weak mechanical properties. ? We took a new approach to reinforce mechanical properties by adding polyvinylpyrrolidone before sol-gel process. ? The reaction between PVMDMS and PVP occurred in sol-gel system ? As a result, PVMDMS_PVP aerogels shown improved elastic modulus and thermal stability
