Description

technical field [0001] The invention relates to the field of dual-curing transparent conductive adhesives, in particular to a flexible UV-heat dual-curing transparent conductive adhesive and a preparation method thereof. Background technique [0002] At present, the conductive adhesives that appear on the market are basically made by filling conductive powder into the adhesive. The conductive adhesive system can be divided into acrylic system, epoxy system and silicone system. Among them, the acrylic system has the advantages of fast curing, high adhesion, and wide Tg adjustment range, but its moisture resistance and aging resistance are poor; the epoxy system has good adhesion and aging resistance, but its cured product has high hardness and poor flexibility. , high stress; the silicone system cures quickly and has good aging resistance, but poor adhesion. [0003] With the development of technology, flexible electronic products have become an important trend in the devel...
