Abstract
Disclosed herein is a composite material that is formed from a polymer, acetylated collagen and graphene, which can be used as a super-capacitor material. Also disclosed herein are methods of making said composite material and its intermediates, as well as a supercapacitor made using said material.
Claims18
A composite material comprising:
- graphene;
- acetylated collagen;
- and
- a polymeric material providing a polymeric matrix, wherein
- the graphene is attached to the acetylated collagen to form a graphene-collagen composite and the graphene-collagen composite is dispersed within the polymeric matrix,
- wherein:
- the weight:weight ratio of graphene to collagen in the graphene-collagen composite material is from 0.1:1 to 3:1;
- and
- the weight:weight ratio of the polymeric material to the graphene in the collagen-graphene composite material is from 500:1 to 2250:1.
