MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202631059592 A) filed by Mr. Pankaj Lochan Sarangi; Dr. Shyama Prasad Mohanty; and Ms. Swikruti Panda on May 11, 2026, for "production Of Biodegradable Polymer Film With Titanate/Sulfur Nanocomposites As Additive".
Inventors include Mr. Pankaj Lochan Sarangi; and Dr. Shyama Prasad Mohanty.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: The present invention relates to a biodegradable polymer film composition and a method for its preparation, wherein a poly(lactic acid) (PLA) and thermoplastic starch (TPS) blend is incorporated with a titanate/sulfur nanocomposite additive to enhance functional properties. The titanate/sulfur nanocomposite is synthesized by hydrothermal treatment of TiO2 nanoparticles in an alkaline medium to form sodium titanate, followed by dispersion in sodium thiosulfate solution and acidification to simultaneously convert sodium titanate into hydrogen titanate nanostructures and precipitate sulfur, thereby forming a titanate/sulfur nanocomposite powder. The nanocomposite powder is incorporated into PLA/TPS blends in the range of 1–5 wt% using melt compounding in a twin-screw extruder in the presence of glycidyl methacrylate and benzoyl peroxide, followed by pelletization and film formation through blown film extrusion. The resulting biodegradable films exhibit improved tensile strength, enhanced ultraviolet radiation retardation, antimicrobial activity against Staphylococcus aureus, and improved compost degradation behavior. The invention provides an industrially scalable biodegradable antimicrobial film suitable for packaging and related applications.
