An anisotropic conductive film (ACF) composition includes a binder having a thermoplastic resin and a styrene-acrylonitrile (SAN) copolymer resin, a curing composition, and conductive particles.

Anisotropic conductive film composition

An anisotropic conductive film composition includes a polymer resin, a first epoxy resin including at least one of a bisphenol epoxy resin, a novolac epoxy resin, a glycidyl epoxy resin, an aliphatic epoxy resin, and an alicyclic epoxy resin, a second epoxy resin including an acetal epoxy resin, an epoxy resin curing agent, and conductive particles.

Anisotropic conductive film composition, anisotropic conductive film including the same, and associated methods

Disclosed herein is an anisotropic conductive film forming composition, including at least one polymer comprising a polymer containing a silane group; at least one polymerizable compound; and a plurality of conductive particles. The at least one polymer may include an elastomeric polymer and a filler polymer, at least one of which contains a silane group. The at least one polymerizable compound may include a cross-linking agent and/or a polymerization reaction enhancer. The cross-linking agent may also have a silane group. In addition, the film forming composition may include a solvent. The film forming composition is advantageous in that the resulting anisotropic conductive film exhibits enhanced peel and adhesive strength and low electrical contact resistance.
