Abstract: The present invention provides a method for making a porous silica aerogel composite membrane. The porous silicon oxide aerogel composite membrane includes a porous aluminum oxide membrane having a plurality of macro pores with an average diameter larger than 50 nm and a porous silica aerogel membrane formed on at least one side of the porous aluminum oxide membrane and the macro pores of surface layers of the porous aluminum oxide membrane where the porous silica aerogel membrane has a plurality of meso pores with an average diameter of 2˜50 nm and is derived from methyltrimethoxysilane precursor by a sol-gel synthetic method.

Abstract: A hydrophobic porous silica aerogel composite membrane for a vacuum membrane distillation device and a vacuum distillation method are disclosed. The vacuum membrane distillation device has a case and the hydrophobic porous silica aerogel composite membrane accommodated in the case to divide a chamber defined by the case into a feed part configured to feed a first fluid containing water molecules and a permeate part configured to collect a second fluid containing the water molecules. The hydrophobic porous silica aerogel composite membrane includes a porous aluminum oxide membrane that has a plurality of first pores with average pore diameter larger than 50 nm and a porous silica aerogel membrane that has a plurality of second pores of 2 to 50 nm and is formed on at least one side of the porous aluminum oxide membrane facing the feed part by methylmethoxysilane as a precursor and a sol-gel synthetic process.
