Abstract
The invention provides a method for preparing a flexible high resistance multi-layer transparent conductive film which includes steps as follows: forming a titanium dioxide layer, a silicon dioxide layer, an indium tin oxide layer, a zinc-aluminium oxide layer or zinc-gallium oxide layer continuously and orderly on one surface of a flexible base material PET polyester film by using a mid-frequency magnetron sputtering technique; temperature reaching to 120 DEG C or more by using heat energy generated by bombardment continuously and deposition of the high-energy particle on the PET polyester film, and controlling oxide-indium atom ratio between 1.26-1.29 for obtaining the indium tin oxide layer with crystal structure; adhibiting another side of the PET polyester with one side of the second layer PET polyester, setting a hard coating on another side of the second layer PET polyester; forming the titanium dioxide layer and the silicon dioxide layer continuously and orderly on the hard coating by using mid-frequency magnetron sputtering technique. The product has better resistance stability and durability, has advantages of short production flow, high efficiency and low cost. The product is not easy to warp in follow processing flow.
