The invention discloses a dimming diaphragm suitable for curved glass, dimming laminated glass and a manufacturing method. The flat dimming diaphragm is preformed by means of hot pressing and the like, so that the fitting degree of the flat dimming diaphragm and the curved glass is increased; by improving the polymer matrix layer, the shape of the diaphragm does not retract in the subsequent laminated glass manufacturing process; in this way, wrinkles caused by the fact that the diaphragm is not attached to the curved glass can be effectively avoided. In addition, by combining conductive layer materials with higher applicability, abnormal electric connection caused in the membrane forming process is avoided. 本发明公开了一种适用于曲面玻璃的调光膜片、调光夹层玻璃以及制造方法。本发明依靠热压等方式将平整调光膜片预成型，增加与曲面玻璃的贴合度；通过改善聚合物基质层，在后续夹层玻璃制作过程中，膜片的形状也不会回缩；通过这种方式可以有效避免因膜片与曲面玻璃不贴合造成的褶皱。另外，本发明通过组合适用性更强的导电层材料，避免了膜片成型过程中造成的电连接异常。
