Synthesis and Properties of Conducting Polymers and their Hybrids with Inorganic Molecules

Abstract

The expanding fields of conducting polymers nanocomposites are generating many exciting new materials with novel optoelectronic properties. It is of great significance to explore the performance of hybrid composites in these established areas and to develop the reliable and scalable synthetic methods for the synthesis of conducting polymers inorder to provide the base for research and application. The main objective of the present research work is the quest of processibility. optical properties and to understand charge transport mechanism in these conducting polymers. newlinePoly thiophene represents the most important conjugated polymer due to its excellent optical and electrical properties as well as exceptional thermal and chemical stability makes it a promisable candidate for light emitting diodes, field effect transistors and organic solar cells. In lieu of above. the aim of the thesis is to understand the basic science of the synthesis. characterization of Poly (3-hexyl thiophene) and Poly (3-methoxy thiophene) and their composites with CdSe. CdTe quantum dots. Zna. NiO, Ti02. The wide band gap ZnO and TiO2 has good electrical conductivity. high transparency and higher exciton binding energy. These wide band gap nanocrystals have good intrinsic n-type conductivity which can be further enhanced upon doping. These hybrid composite of conducting polymers and inorganic molecules integrate the useful characteristics of both polymer and inorganic molecule within a single component.
