MUMBAI, India, Nov. 21 -- Intellectual Property India has published a patent application (202511085836 A) filed by Indian Institute Of Technology, Kanpur, Uttar Pradesh, on Sept. 10, for 'a process of fabricating absorption-dominant electromagnetic interference (emi) shielding fabric.'
Inventor(s) include Kamal Krishna Kar; Swati Gangwar; and M. Jaleel Akhtar.
The application for the patent was published on Nov. 21, under issue no. 47/2025.
According to the abstract released by the Intellectual Property India: "The invention provides an EMI shielding fabric utilizing recycled human hair-derived carbon and carbon nanofibers. This approach not only repurposes waste materials into functional products but also enhances electrical conductivity and shielding efficiency. The fabricated material exhibits superior EMI shielding performance, excellent stability in varying pH environments, flame retardancy, and hydrophobicity. These multifunctional properties make the developed fabric highly suitable for applications in wearable electronics and military-grade protective tents, offering effective protection against unwanted electromagnetic radiation. The proposed methodology for utilizing biowaste, specifically human hair-derived carbon, as a precursor for EMI shielding films not only significantly reduces production costs but also contributes to sustainable waste management and environmental remediation."
