Al2O3 aerogels has been used as insulating materials in the high-temperature areas due to the excellent high-temperature resistance， especially at the temperatures above 1000 ℃. But the hydrophilicity of Al2O3 aerogels makes it easy to absorb water steam， damaging the skeleton and the thermal insulating performance. In this work， a polyvinyltrimethoxysilane （PVTMS） hydrocarbon chain polymer is synthesized with vinyltrimethoxysilane （VTMS） as the raw material to solve above problems. Then Al-polyvinyltrimethoxysilane aerogel （AlPVSA） is prepared by in-situ polymerization using PVTMS and Al（NO3）3·9H2O as precursors. The polyvinyl chain is introduced into the Al2O3 skeleton， and the transformation from hydrophilicity to hydrophobicity is realized by adjusting the content of organic components， where the maximum contact angle is up to 136.8°. The transformation mechanism is further studied based on the surface energy and roughness. The mechanical properties of AlPVSA are improved by participating in the network-formation of organic components， and the compression modulus is maximized to 3.9 MPa when n（PVTMS/Al）=1. AlPVSA with high content silicon-polyvinyl chain is easy to form mullite phase after being heated at 1200 ℃， which lead to higher linear shrinkage （the maximum is 53.8%） and destruction of microstructure，resulting in thermal stability decrease.
