  • Process for producing graphene, a graphene and a substrate thereof
    Patent number: 10807871
    Abstract: The present disclosure relates to a process for producing graphene, wherein the process is simple and economical. In the said process the substrate is contacted with vaporized seedlac to produce graphene on a substrate including but not limited to conductive material and non-conductive material. The disclosure further relates to a graphene which is impermeable to ions and molecules, resistant to oxidation and is hydrophobic. The disclosure furthermore relates to a substrate comprising graphene, said substrate is resistant to corrosion, resistant to oxidation and is hydrophobic.
    Type: Grant
    Filed: July 21, 2017
    Date of Patent: October 20, 2020
    Assignees: TATA STEEL LIMITED, CENTER FOR NANO AND SOFT MATTER SCIENCES
    Inventors: Shyam Kumar Choudhary, Sumitesh Das, Giridhar Udapi Rao Kulkarni, Rajashekhar Pujar
