WebThe dielectric constant of polymer films can be varied by systematically varying the constituent layers of the composite. PPC was ideal as a substrate and dielectric. Its surface energy was 47 mN m-1, and the dielectric constant was 3. PPC exhibits good compatibility with organic semiconductors. Further, it is biocompatible. <imagetitle></imagetitle></h1>
