What Is an Anisotropic Conductive Film?
Anisotropic conduction film (ACF) is a specialized material designed to conduct electricity in specific, controlled directions.
This material combines conductive particles—like silver, copper, or carbon nanotubes—with substrates such as polyimide, PET, or glass to create a directionally conductive matrix. Techniques including magnetic alignment, spin coating, and templating are pivotal in orienting the conductive particles, ensuring conductivity occurs only along desired paths.
ACF’s unique properties make it essential in various applications, from touch panels and displays to solar cells, EMI shielding, and smart textiles. Its production involves the careful preparation and alignment of conductive particles on a substrate, followed by necessary surface treatments to achieve the intended conductivity characteristics.
