Abstract

Polymers and polymer-based materials are getting more attention for the past newlineseveral years because of its relatively low cost and wide range of applications in newlinemodern devices. The design and fabrication of lighter, smaller, flexible, ecofriendly, newlinelow cost electronic and optoelectronic devices demands the integration of polymer newlinematerials into our new types of equipment. Among the polymeric materials, newlineconjugated polymers are particularly attractive because it can be synthesized in a newlinerelatively easy way even with solution based processing techniques. The conjugated newlinepolymers are flexible with respect to molecular design and are suitable for large area newlinefabrication. Interestingly, conducting polymers such as polyaniline and polypyrrole newlineare unique in its properties which are biocompatible and possess good redox newlinecharacteristics as well as tunable electrical and photophysical properties. The newlinepolymers derived from plant based sources are relatively economic, ecofriendly and newlinethe electronic grade materials obtained from these polymers can be integrated in to newlinethe optoelectronic devices and biomedical applications. Radio frequency (rf) newlinepolymerization is a versatile, single step polymer thin film fabrication method which newlinecan be applied to polymerize volatile liquids that cannot be polymerized through newlineconventional polymerization methods. Nowadays, radio frequency plasma polymerized newlineconjugated conducting polymers have been important materials especially to use in newlineorganic optoelectronic devices as well as for the realization of functionalized newlinepolymer coated materials for biomedical applications. newlineThe present thesis focused on the fabrication of polymer thin films based on newlinethe rf plasma polymerization technique on glass and silicon substrates, and as well newlineas on Fe3O4 nanoparticles. The effect of low energy (100 keV) Ag and P ion newlineimplantation on the rf plasma polymerized thin films are also investigated.
