▎ 摘　　要

NOVELTY - Double-sided polyimide film with function of absorbing electromagnetic wave, comprises two layers polyimide film substrate (1), whose upper and lower parts are provided with a first trapezoidal groove (2) arranged at interval. First filter coating (3) is coated on the opposite surfaces of the two layers polyimide film substrate, and the upper and lower of the first filter coating are provided with a first trapezoidal platform (4) inserted into the first trapezoidal groove. The outer side of each layer polyimide film substrate is further provided with a second trapezoidal groove (5) arranged at intervals. A layer of second filter coating (6) is also coated on the outer surface of each layer of polyimide film substrate. Second filter coating is provided with a second trapezoidal platform (7) inserted into the second trapezoidal groove on the polyimide film substrate. USE - Double-sided polyimide film with function of absorbing electromagnetic wave. ADVANTAGE - The double-sided polyimide film has high temperature resistance, excellent adaptability and flexibility, high efficiency of corrosion resistance and wear resistance, and excellent sliding property and elasticity. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the double-sided polyimide film with function of absorbing electromagnetic wave. 1Polyimide film substrate 2First trapezoidal groove 3First filter coating 4First trapezoidal platform 5Second trapezoidal groove 6Second filter coating 7Second trapezoidal platform
