Electrically conducting hydrophilic co-polymers

An electrochemical cell, comprising:

• a homogenous, isotropic, cross-linked electronically active hydrophilic co-polymer;
• and
• two electrodes with the co-polymer located therebetween,
• wherein the co-polymer is formed by a process 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;
• and
• c. polymerising the co-monomer mixture to form the co-polymer,
• 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,
• wherein the co-polymer is self-supporting, and
• wherein the electrochemical cell is a supercapacitor.
