▎ 摘  要

NOVELTY - Electromagnetic shielding composite material with temperature response characteristics, comprises a functional material, and the functional material is compounded with a substrate material. USE - The electromagnetic shielding composite material is useful for smart temperature control electromagnetic shielding switch of an electronic device. ADVANTAGE - The electromagnetic shielding composite material with temperature response characteristics: is capable of tuning the electromagnetic response to the heat, with a recyclable feature, which avoids the traditional intelligent electromagnetic shielding material need to respond to external stimulation by deformation of the design structure. It greatly improves the reliability of the material, has wide application prospect, and has important meaning for the application in the device as an intelligent temperature control electromagnetic shielding switch. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing electromagnetic shielding composite material with temperature response comprising uniformly ball milling and blending vanadium dioxide and the gel, solution or dispersion liquid of the base material, afterwards, freeze-forming and freeze-drying, and mechanically pressing into a film, alternatively, heat curing molding.
