  • COMPOSITION AND METHOD FOR PROVIDING WATER-REPELLENCY
    Publication number: 20230303745
    Abstract: The disclosure provides a water-repellent treatment composition including a functionalised copolymer of a monomer including a di-carboxylic acid anhydride group and a monomer selected from vinyl monomers. The vinyl monomer and optionally the monomer include a di-carboxylic acid anhydride group and form a polymer backbone. At least a portion of the di-carboxylic acid anhydride groups are functionalised by a graft pendant group including two or more fatty aliphatic groups linked to the polymer backbone via an ester, amide or imide of the dicarboxylic acid anhydride.

  • Membrane
    Patent number: 10777833
    Abstract: An electrolyte membrane including (i) a porous mat of nanofibres, wherein the nanofibres are composed of a non-ionically conducting heterocyclic-based polymer, the heterocyclic-based polymer comprising basic functional groups and being soluble in organic solvent; and (ii) an ion-conducting polymer which is a partially- or fully-fluorinated sulphonic acid polymer. The porous mat is essentially fully impregnated with ion-conducting polymer, and the thickness of the porous mat in the electrolyte membrane is distributed across at least 80% of the thickness of the electrolyte membrane. Such a membrane is of use in a proton exchange membrane fuel cell or an electrolyser.
