    • The invention solves a problem of that sufficient adhesive intensity to satisfy recent demand for high adhesive property cannot be obtained by conventional surface treatment, and provides a method of improving adhesive property of polyimide film and achieving distinctly improved effect of adhesive property. The invention further provides novel polyimide film having improved adhesive property.A method for improving adhesive property of polyimide film according to the present invention comprises a combination of steps of;execution of a liquid applying process for treating polyimide film surface by exerting physical mechanical force on said film surface under the condition of that said film surface remains wet with water or organic solvent, or solution of organic solvent or aqueous solution; and execution of a surface treatment process for treating polyimide film surface by performing selected treatment among flame treatment, alkaline treatment, coupling agent treatment or surface treatment by way of projecting grinding material of fine grading onto film surface at high velocity, and said steps are performed in an arbitrary order. For example, using a surface treating device 10 shown in FIG. 1, consecutive execution of a surface treatment process for treating film surface, a liquid applying process and a drying process is realized by that polyimide film 22 is run from a feeding device 18 to a winding device 20.
    • 本发明解决了通过常规的表面处理不能获得足够的粘合强度以满足最近对高粘合性能的要求的问题,并且提供了改进聚酰亚胺膜的粘合性能并且显着提高粘合性能的效果的方法。 本发明还提供了具有改进的粘合性能的新型聚酰亚胺膜。 根据本发明的改进聚酰亚胺薄膜的粘合性的方法包括以下步骤的组合: 执行用于在所述膜表面保持用水或有机溶剂润湿的条件下或在有机溶剂或水溶液的溶液的条件下在所述膜表面上施加物理机械力来处理聚酰亚胺膜表面的液体施加过程; 并且通过在火焰处理,碱处理,偶联剂处理或表面处理中进行选择的处理,通过以高速投影细微分级的研磨材料到薄膜表面上来执行用于处理聚酰亚胺膜表面的表面处理工艺,并且执行所述步骤 以任意顺序。 例如,使用图1所示的表面处理装置10, 如图1所示,通过聚酰亚胺膜22从供给装置18向卷绕装置20运行,连续执行用于处理膜表面的表面处理工艺,液体施加处理和干燥处理。
