| titleOfInvention | A kind of phosphonated polyolefin grafted benzimidazole polymer proton exchange membrane and its preparation method and application |
| abstract | The invention provides a phosphonated polyolefin grafted benzimidazole polymer proton exchange membrane and a preparation method and application thereof. Since the material of the present invention uses polyolefin as the main chain, the graft copolymer is synthesized with HBPBI and LPBI as the branched chain. The microscopic phase-separation morphology of the polymers with the two properties is used to construct proton transport channels, thereby improving the proton conductivity; in addition, the polyolefin-based flexible backbone drives the HBPBI and LPBI branched chains to move at high temperature to reduce the activation energy of proton migration and promote The migration of phosphoric acid or protons increases the proton conductivity. The use of the hyperbranched structure can not only accommodate more phosphoric acid, but also a large number of active sites in the hyperbranched structure can be grafted with a large amount of organic phosphonic acid, which can reduce the loss of phosphoric acid and improve the retention rate of proton conductivity through a two-pronged approach. High temperature proton exchange membranes with high proton conductivity and high proton conductivity retention are obtained at lower phosphoric acid doping levels and low volume swelling. |
