A kind of preparation method of crosslinked organic-inorganic alkaline polyelectrolyte membrane |
| abstract |
The invention relates to the technical field of fuel cells, and specifically discloses a preparation method of a cross-linked organic-inorganic composite alkaline polyelectrolyte membrane. The preparation method of the invention comprises the following steps: (1) purifying bacterial cellulose; (2) ) Coating silica on bacterial cellulose membrane by sol-gel method; (3) modifying carbon-carbon double bonds on the bacterial cellulose membrane coated with silica; (4) dissolving cationic monomers to obtain cationic Monomer solution; (5) In-situ polymerization of the cationic monomer solution is filled in the pores of the silica-coated bacterial cellulose membrane, that is, it is obtained. The invention utilizes the hydroxyl groups on the surface of bacterial cellulose to coat the surface of nanofibers with silicon dioxide, which increases chemical stability and mechanical properties and facilitates further modification; in addition, the cationic polyelectrolyte is polymerized and filled in-situ to further improve the The ionic conductivity is expected to have broad application prospects in the field of alkaline polyelectrolyte fuel cells. |
