Electrically conducting hydrophilic co-polymers

A process of forming a cross-linked electronically active hydrophilic co-polymer comprising the steps of:

• a. mixing an intrinsically electronically active material 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, wherein the co-monomer mixture comprises water in an amount of 5%-50% by weight based on a total weight of the co-monomer mixture;
• and
• c. polymerising the co-monomer mixture,
• wherein, in step b, the at least one hydrophilic monomer and the at least one hydrophobic monomer are added to the intermediate mixture prior to the addition of the cross-linker, and wherein, in step b, the at least one hydrophilic monomer is added to the intermediate mixture prior to the addition of the at least one hydrophobic monomer.
