▎ 摘 要
NOVELTY - Anisotropic conductive adhesive film with high shelf life comprises a first solution, a second solution, and an initiator in a mass ratio of (12-20):(20-26):1. The first solution includes an adhesive, a curing agent and a free radical polymerization inhibitor, and the content of the free radical polymerization inhibitor in the first solution is 0.1-0.5 wt.%. The second solution includes a resin substrate, conductive particles and carboxy-modified graphene, and the content of the carboxy-modified graphene in the second solution is 2.1-4.5 wt.%. USE - The adhesive film is used in anisotropic conductive film technology field, and aqueous conductive films. ADVANTAGE - The method realizes prolonging the shelf life of the anisotropic conductive adhesive film while solving the side effect of low curing modulus caused by too much low-temperature initiator. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the anisotropic conductive adhesive film, comprising taking raw materials, mixing adhesive, curing agent, free radical polymerization inhibitor and first solvent to form a first solution, mixing resin substrate, conductive particles and carboxy-modified graphene with second solvent to form second solution, then mixing the first solution and the second solution and adding initiator at the same time, and uniformly mixing and coating to obtain anisotropic conductive adhesive film with high shelf life.
