  • Patent number: 11702496
    Abstract: A process of forming a cross-linked electronically active hydrophilic co-polymer is provided and includes the steps of: a. mixing an intrinsically electronically active material and at least one compound of formula (I) with water to form an intermediate mixture; b. adding at least one hydrophilic monomer, at least one hydrophobic monomer, and at least one cross-linker to the intermediate mixture to form a co-monomer mixture; and c. polymerising the co-monomer mixture. Formula (I) is defined as: where R1 and R2 are independently optionally substituted C1-C6 alkyl and X? is an anion.

  • Patent number: 10843812
    Abstract: Components having fibre-reinforced composite structures are disclosed. The component comprises a plurality of structural fibres embedded in a cured matrix material and a plurality of nanostructures such as carbon nanotubes extending from one or more of the structural fibres. In some embodiments a density of the nanostructures is at least 107 nanostructures per cm2 of surface area of the one or more structural fibres. In some embodiments, the nanostructures extend from an outer fibre proximal to an outer surface of the component but not from an inner fibre distal from the outer surface. In some embodiments the one or more structural fibres from which the nanostructures extend are free of a sizing agent.
