METHOD FOR PREPARING POLYMER COATED AEROGEL, POLYMER COATED AEROGEL PREPARED THEREBY AND INSULATION MATERIAL COMPRISING THE SAME

摘要

A method of preparing polymer-coated aerogel is provided to improve mechanical stability even while maintaining an inner structure of the aerogel. A method of preparing polymer-coated aerogel comprises the following steps of: mixing aerogel with a polymer material to absorb the polymer material onto a surface of the aerogel(a); heat-treating the polymer-coated aerogel(b); and additionally removing residual polymer materials which are not absorbed onto the aerogel. The polymer-coated aerogel includes aerogel(1) and a polymer layer(3). The aerogel has a plurality of pores inside.
