MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202541053050 A) filed by Manipal Academy Of Higher Education on May 31, 2025, for A Method And Composition For Developing Ceramic-Coated Carbon Nanotube Reinforced Thermoplastic Polymer Nanocomposite.
Inventors include Suhas. K.; Murthy Brn; and Anupama R Hiremath.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: The invention discloses a polymer nanocomposite (100) engineered for deployment in high temperature and high wear applications, wherein a thermoplastic polymer matrix (101) is reinforced with ceramic-coated carbon nanotubes at a defined weight fraction. The carbon nanotube reinforcement phase (103) undergoes sequential surface functionalization and hydrothermal ceramic coating deposition prior to incorporation into the thermoplastic polymer matrix (101), ensuring enhanced interfacial compatibility and uniform nanoscale dispersion. The polymer nanocomposite (100) is fabricated through melt blending followed by compression molding under controlled process parameters. The metal oxide ceramic coating on the surface of the carbon nanotube reinforcement phase (103) acts synergistically with the reinforcement to improve interfacial stress transfer, promote crack arresting behavior, and elevate both mechanical strength and thermal stability of the polymer nanocomposite (100) beyond additive expectations. The invention provides a processing-friendly nanocomposite platform suitable for structural and tribological applications demanding performance under thermally and mechanically demanding service conditions.
