| titleOfInvention | A kind of phosphonated polyolefin/benzimidazole polymer composite proton exchange membrane and its preparation method and application |
| abstract | The invention relates to a phosphonated polyolefin/benzimidazole polymer composite proton exchange membrane and a preparation method and application thereof. The composite proton exchange membrane of the present invention uses phosphonated polyolefin, and the phosphonic acid is restrained by the polymer chain and cannot be lost with water. The composite proton exchange membrane can effectively reduce the loss of phosphonic acid and phosphoric acid. In addition, the glass transition temperature of phosphonated polyolefins is lower than that of PBIs, which can promote the movement of phosphonic acids in composite proton exchange membranes with higher mobility at high temperatures to improve proton conductivity. The invention can obtain high proton conductivity (0.09S/cm) and high proton conductivity retention rate (more than 73% after 10 deionization impregnations) at lower phosphoric acid doping level (<10). ). |
