MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202641018722 A) filed by Vellore Institute Of Technology, Vellore, Tamil Nadu, on Feb. 19, for 'method for preparing a self-healable double-network hydrogel composition for shock absorption in protective equipment.'
Inventor(s) include Dr. Chandan Maity; and Mr. Dinesh Kumar.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a self-healable double-network hydrogel composition (100) for shock absorption, impact-energy dissipation, and structural recovery in protective, cushioning, and packaging applications. The composition (100) comprises a polymeric network (102) including agarose (106) cross-linked through reversible borate ester linkages (108) formed using a borate source (110), and a supramolecular network (104) including guanosine assemblies (112) stabilized by potassium ions (114) to form G-quartet structures (116). The polymeric network (102) and the supramolecular network (104) are interpenetrated to form a double-network architecture (118) that enables controlled deformation under impact and rapid reformation of dynamic interactions after load removal, thereby reducing rebound and maintaining mechanical integrity. A method is also provided that includes dissolving guanosine (112) and boric acid (110) in water (120), adding agarose (106) under heating, introducing a potassium ion source to generate G-quartet structures (116), and cooling to obtain the composition (100)."
