Newly Developed LCP Solvent Casting Film and Its Applications

摘要

Commercial aromatic liquid-crystalline polymers (LCP) are known to be unable to dissolve in any common organic solvents. Recently, we succeeded in the development of innovative solvent-casting type LCP by a design of the molecule structure. In addition to standard LCP film properties such as environmental compatibility, moisture resistance and heat resistance, the casting-type LCP film exhibits less anisotropy, high adhesion to copper foils and peculiar behavior of modulus of elasticity suitable for mounting IC chip. The solvent-casting type LCP has many advantages to be applied for the various electro devices.
