Abstract: A method for producing a silver-coated polymer microsphere includes admixing a polymer microsphere with a dipping solution containing water, a protic solvent, a tin compound, and hydrochloric acid and subsequently subjecting a resultant first mixture to ultrasonication so that a tin adsorption layer is formed on a surface of the polymer microsphere, immersing the polymer microsphere having the tin adsorption layer in a silver complex solution to obtain a second mixture, diluting the second mixture with water to form a diluted second mixture, and dropping a reducing solution into the diluted second mixture, so that a silver coating layer is formed on a surface of the tin adsorption layer of the polymer microsphere.

Abstract: A method for producing an anisotropic conductive film, which includes mixing a base polymer with an initiator and a first solvent to obtain a first mixture, dispersing conductive microspheres in an alcohol or a second solvent containing a surfactant to obtain a second mixture, mixing the first mixture with a monomer, a binder, and the second mixture to obtain a third mixture, and laminating the third mixture on a carrying film, followed by drying, so as to obtain the anisotropic conductive film. An anisotropic conductive film produced by the method and a composition for forming the anisotropic conductive film are also disclosed.
