This application provides a method for preparing the
edge structure of a multilayer dimming film. The method involves
plasma activation treatment of the
cut end face of the film to form an activation layer,
coating its surface with an interface anchoring liquid to form a flexible anchoring layer, and then applying an edge-sealing agent followed by a three-stage gradient curing process. This achieves high strength, durability, and self-healing capabilities at the film edge. Through the synergistic effect of the interface anchoring liquid and the edge-sealing agent, this method significantly improves the adhesion, protection, and
mechanical stability of the film edge, while also exhibiting resistance to
environmental aging and self-healing properties. It solves the problems of easy peeling,
water seepage, and performance degradation at the edges of traditional dimming films, and has high industrial application value.
