Example Embodiment
[0028] Example 1
[0029] The gas deep dehumidification membrane includes two parts: a modified porous skeleton and a water removal functional resin composite; the modified porous skeleton plays a supporting role as the main body of the dehumidification membrane; the water removal functional resin composite can be selectively and directionally removed Water molecules, the two promote each other to complete the deep removal of water molecules in the gas.
[0030] The modified porous skeleton and the water-removing functional resin composite are combined with each other to form an integral structure by filling or coating; the mass proportion of the modified porous skeleton in the gas deep dehumidification membrane is 5-90%.
[0031] The modified porous skeleton is obtained by modifying the porous skeleton by surface plasma or chemical grafting; the porous skeleton is a polytetrafluoroethylene film, a polyvinylidene fluoride film, a polyacrylonitrile film, a polyethylene film, P...
