preparation example Construction

[0074] The preparation method of the above-mentioned dual-polymer composite membrane will be described in detail below. The method includes:

[0075] (1) Prepare a liquid solution for the polymer coating.

[0076] The material used for the polymer cover layer is polydimethylsiloxane or polyvinylidene fluoride. Specifically, polyvinylidene fluoride is dissolved in dimethylacetamide (DMA) to form a liquid solution. Polydimethylsiloxane itself is liquid and can be directly applied to step (2). When polydimethylsiloxane is used for the polymer covering layer, polydimethylsiloxane and curing agent (vulcanizing agent, usually at a ratio of 10:1) are required. The curing agent used is a commercially available conventional curing agent, such as Dow Corning 184.

[0077] (2) Uniformly coat the polymer covering layer with a liquid solution on the surface of the polymer porous membrane layer. The material used for the polymer porous membrane layer is polypropylene porous membrane, p...
