Title:
GRAPHENE HYDROGEL AND METHOD FOR PREPARATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/135380
Kind Code:
A1
Abstract:
Provided are a graphene hydrogel and a method for preparation thereof, the starting material formulation of said graphene hydrogel including the following components in parts by weight: 10-50 parts of vinyl-terminated polydimethylsiloxane; 10-50 parts of vinyl-terminated polymethylvinylsiloxane; 1-10 parts of methyl-terminated polysiloxane containing hydrogen; 1-10 parts of hydrogen-terminated polysiloxane; 0.1-5 parts of silicon–hydrogen chain extender; 10-50 parts of graphene; 1-10 parts of carbon nanotubes; 0.1-2 parts of tackifier; 0.1-2 parts of carbon interface treatment agent; 1-5 parts of inert diluent, 0.01-1 part of acetylenic alcohol inhibitor; and 0.01-1 part of platinum–gold catalyst. In comparison with the prior art, the graphene hydrogel and graphene-based electromagnetic and thermal shielding silicone materials utilize the excellent electronic and thermal effects and other physical properties of graphene, not only achieving the performance of simultaneous electromagnetic and thermal shielding, but the components also act in synergy, enabling excellent mechanical strength and reliable stability.
