MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202631008077 A) filed by National Institute Of Technology, Silchar, Assam, on Jan. 27, for 'a process for preparation of coconut shell derived reduced graphene oxide incorporated hap-pmma composite bone scaffolds.'
Inventor(s) include Mahmun, Amdadul; Deoghare, Ashish Bhalchandra; and Barua, Emon.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a process for the preparation of reduced graphene oxide incorporated HAP-PMMA composite bone scaffolds. Coconut shell bio-waste is converted into graphite, oxidized into graphene oxide using the Improved Hummers' method, and thermally reduced to obtain reduced graphene oxide. Hydroxyapatite is synthesized by a wet chemical precipitation technique. Electrically conductive composite scaffolds incorporating reduced graphene oxide, hydroxyapatite, and polymethyl methacrylate are fabricated using a modified gas foaming technique with ammonium bicarbonate as a foaming agent. Scaffolds with varying reduced graphene oxide concentrations are developed and characterized for physicochemical, structural, mechanical, electrical, biodegradable, biocompatible, and bioactive properties. The reduced graphene oxide containing scaffolds show improved performance. The scaffold comprising 1 wt% reduced graphene oxide, 69 wt% hydroxyapatite, and 30 wt% polymethyl methacrylate exhibits superior compressive strength, electrical conductivity, porosity, biodegradability, and viability. The invention demonstrates sustainable utilization of coconut shell bio-waste and provides an electrically conductive composite scaffold."
