    • Joël Daveas received hs doctoral degree in Materials Science from the University of Lyon. He has been engaged in studies on nonlinear optics at the university P. and M. Curie in Paris and was involved in the development of high flux ion sources at teh C. E. A. (Agency for Atomic Energy). He joined the Department of Materials Physics (associated to C.N.R.S) at the University of Lyon in 1974 as C.N.R.S. researcher were he contributed to the early studies on the ion beam modification of insulators. His interests have forused mainly on radiation-polymer interactions and he has authored over 50 papers among which 30 are on the effects of ion beams in organics.

Abstract

Altough no polymers are intrinsic conductors, conjugated polymers have been shown to become conducting when heavily doped. However, advances are still needed to achieve both the high stability and conductivity required in most applications. Photon, plasma and ion beam processing of organic materials offer opportunities to induce new properties (e.g. insulating or conducting) in organic precursors. Plasma treatments have led to the remarkable development of diamond-like film synthesis. This contribution is a review of the recent advances in ion bea modified polyimides, a new variety of high-performance conducting polymers. Related effects like metal-adhesion enhancement will also be discussed.
