Relevance of Plasma Processing on Polymeric Materials and Interfaces

Abstract With the advent of emerging technologies all over the world at the end of 20th century and in the beginning of 21st century, polymers have played a huge role in transforming conceptual ideas into structural integrities useful for mankind. Even though polymers of desired properties can be tailored through a synthesis route, considering the cost aspects it is preferable to modify the existing polymers through surface/interface engineering techniques in order to meet the manufacturing requirements of engineering industries all over the world. The behavior of polymers at the interfaces is of fundamental importance in a wide range of technologies and applications. Adhesion problems exist with the bonding of polymers, the adhesion of coatings to polymer surfaces and interface/interphase problems associated with melt-blended polymers and polymer micro, as well as nano composites, are recurring and challenging areas in polymer-based industries. With a thorough understanding of the surface and interface phenomenon in polymer multiphase systems, one can engineer their interfacial properties by controlling the interface/interphase region leading to the development of advanced materials with multifunctional properties. This chapter discusses most recent developments in the area of surface engineering of polymeric interfaces with special reference to the plasma surface modification technique.
