Abstract

The invention discloses an electromagnetic-radiation-resistant, waterproof and air-permeable film material. The preparation method for the electromagnetic-radiation-resistant, waterproof and air-permeable film material comprises the following steps: modifying a porous expanded polytetrafluoroethylene film through plasma treatment, then assembling a copolymer film with an active terminal group ontothe surface of the modified porous expanded polytetrafluoroethylene film and carrying out curing, loading active palladium chloride onto a side chain of the active copolymer film through ion exchange, and subjecting the surface-activated porous expanded polytetrafluoroethylene film to electroless deposition so as to obtain a surface-copperized porous expanded polytetrafluoroethylene film. The preparation method provided by the invention has simple operation, is economical and environment-friendly, and is applicable to industrial production. Meanwhile, the bonding force between the surface-copperized porous expanded polytetrafluoroethylene film and a copperized layer is strong; the copperized layer is uniform, has controllable density, can prevent electromagnetic radiation and has waterproof and air-permeable functions; and the material provided by the invention can be widely used for radiation protection of communication devices, industrial automation devices, radio-frequency and microwave medical devices, military equipment, high-voltage electrical apparatus and transportation tools under harsh conditions.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to an anti-electromagnetic radiation waterproof and breathable film material and a preparation method and application thereof. Background technique [0002] Porous expanded polytetrafluoroethylene film has excellent properties such as chemical stability, electrical insulation, thermal stability, and low surface energy. The composite material prepared by surface electroless copper plating can not only effectively prevent electromagnetic radiation but also have Waterproof and breathable function, and because of the high strength of the film, it can be widely used in various aspects of civil and military facilities. [0003] The essence of electroless copper plating is to reduce copper ions through the reducing agent in the solution and deposit them on the surface of the plated parts. Electroless copper plating generally requires a small amount of catalyst, and the mo...
