Polydopamine-modified hollow metal-organic framework-modified polymer hybrid proton exchange membrane and its preparation |
| abstract |
The invention belongs to the technical field of membranes, and discloses a polydopamine-modified hollow metal-organic framework-modified polymer hybrid proton exchange membrane and preparation thereof. The preparation includes the following steps: (1) using a metal salt and a ligand to react to obtain Corresponding metal-organic framework MOF; (2) placing the MOF in an acid aqueous solution for etching to obtain a hollow metal-organic framework H-MOF; (3) putting the H-MOF into a buffer solution of dopamine hydrochloride, and stirring the reaction to obtain a polymer. Dopamine-modified hollow metal-organic framework H-MOF-D; (4) adding H-MOF-D into a sulfonated polymer solution to form a casting solution and forming a membrane material, soaked in hydrogen peroxide, acid and deionized water, A polydopamine-modified hollow metal-organic framework-modified polymer hybrid proton exchange membrane was obtained. The present invention improves the structure and composition of key functional components in the proton exchange membrane, and the obtained proton exchange membrane has excellent proton conductivity under both high and low humidity conditions. |
