Latest Patent Applications: Jiaqi Yan has been involved in several innovative patent applications. One of her latest applications is titled "CURABLE SULFONATED POLYMER COMPOSITIONS." This disclosure relates to a polymer membrane comprising a curable composition that includes a sulfonated hydrogenated styrenic block copolymer (SSBC), a hydroxyl group containing compound, at least one cross-linking agent comprising an epoxy-based compound, and optionally, a radical scavenger. The SSBC consists of at least one block 'S' and at least one block 'R,' with the block 'S' having a degree of sulfonation of at least 10 mol %. The SSBC demonstrates an ion exchange capacity (IEC) of at least 0.5 meq/g, and upon curing, the polymer membrane shows improved proton conductivity and durability.

Another significant application is "BLOCK COPOLYMER COMPOSITION AND ANION EXCHANGE MEMBRANES MADE THEREFROM." This disclosure relates to a composition comprising a quaternized crosslinked epoxy functionalized partially hydrogenated styrenic block copolymer (QxE-pHSBC) and a thermoplastic polymer (TP). The TP is characterized by a tensile strength of >30 MPa, a flexural modulus of >1.8 GPa, and a heat deflection temperature of ≥75° C. The styrenic block copolymer precursor for QxE-pHSBC can have various structures, including sequential diblock, triblock, or coupled structures, with at least one block functionalized and crosslinked.
