Latest Patents

One of Mengjie Chen's latest patents is titled "Polynorbornene-based ion exchange membranes derived from phosphonated polymer and methods of making same." This invention describes a proton exchange polymer that comprises a polynorbornene copolymer with both hydrophobic and hydrophilic blocks. The polymer can be phosphonated to create phosphonic acid functional groups, which are essential for proton exchange. Additionally, the polymer may be crosslinked to form quaternary ammonium groups on the side chains, enhancing its stability and mechanical durability. This proton exchange polymer is particularly useful in fuel cell and electrolyzer applications due to its high-temperature stability.

Another significant patent by Chen is "Anion exchange branched co-polymer with poly(aryl) and a branched compound and quinuclidinium side chains and synthesis thereof." This invention focuses on an anion exchange branched co-polymer that includes poly(aryl) and a branched compound with quinuclidinuium side chains. The co-polymer is designed to be more durable, with reduced creep and a higher ion exchange capacity (IEC) due to its unique structure. The incorporation of free radical inhibitors and cross-linking further enhances its performance, making it suitable for use in anion exchange membranes and membrane electrode assemblies.
