MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641051004 A) filed by Bapatla Surendra Babu; and Irukumalli Priyanka, Tenali, Andhra Pradesh, on April 21, for 'adaptive elastic guard via impact-driven stiffening for foldable display surfaces.'
Inventor(s) include Bapatla Surendra Babu; and Irukumalli Priyanka.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to non-Newtonian solid-state mechanics and flexible optoelectronics. A technical problem with foldable displays is the mutually exclusive relationship between mechanical foldability and surface scratch resistance in static monolithic polymers. The solution is an adaptive surface protection apparatus that dynamically modulates its shear modulus based on applied strain rates. The apparatus comprises a flexible substrate (110) overlaid with an optically transparent protective coating (120). The coating comprises a continuous polymer matrix (122) featuring dynamic supramolecular crosslinks (124) and suspended nanoparticles (126). Under a low applied strain rate vector (310) (e.g., folding), the crosslinks yield reversibly, maintaining a compliant rubber-like state (330). Under a high applied strain rate vector (320) (e.g., scratching or impact), the crosslinks lock, forcing the nanoparticles to jam into rigid hydro-clusters (128), instantly establishing a highly defensive rigid glass-like state (340). The principal use is the passive, reversible protection of foldable display surfaces against physical damage."
