Abstract

Polymers are widely used in all walks of human life and play a vital role in shaping modern man’s activities to be as important and comfortable as they are today. The advances in science and technology made in recent decades owe much to development of polymer science. The synthesis and design of new polymeric materials to achieve specific physical properties and specialized applications, and attempt to find interesting applications involving advanced structures and architectures, are in continuous development in the period of the polymer science.
Electrically conducting polymers such as polyacetylene, polypyrrole, polythiophene and polyaniline have been the subject of intensive research due to their useful electronic properties and for their application. The factor that has motivated much of the work on the synthesis of conducting polymers is the need to find newer materials having a wide range of physical properties such as flexibility and processibility, and conductivity close to that of metals to suit many technological applications.
In the present work, an attempt has been made to review the most interesting and fascinating aspects of conducting polymers. We also propose to synthesize and characterize polyaniline as one of the important conducting material and explore its uses as molecular materials in electronic/electrical devices. Two different applications of PANI have been described in this dissertation and are discussed in two parts.
In the first part of this dissertation, the sequence of reactive steps that lead to thin layers of polyaniline (PANI) attached to the surface of polypropylene films was accomplished to form poly(propylene)-g-poly(acrylicacid)/polyaniline functional hybrids which can be used in antistatic packaging of electronic devices. The nature of different diamines, used for functionalization, toward the chemical attachment of polyaniline in the subsequent in situ polymerisation step is investigated.
The polypropylene films after each derivatisation step, as well as on all the hybrid skin–core poly(propylene)-g-poly(acrylicacid)/polyaniline films were characterized by several techniques such as UV-vis spectroscopy, Fourier-Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscope (SEM) to confirm the success of each step of treatment.
