Surface and Interface Functionalization by Surface Chemical Modification and Nanocoating Technology and Their Application to Joining of Dissimilar Materials

Abstract

We have developed a simple and useful process for fabricating functional polymer and carbon materials modified with a variety of functionalities by surface photochemical modifications. The introduction of the functional moieties on the surface of these materials showed an improvement of their original properties while maintaining the bulk properties of polymer and carbon materials. We will also report on the nanocoating technology for the control of surface and interface functionality and for an application to joining of dissimilar materials with high joint strength for flexible printed circuits（FPC）in 5G networks.
