Thesis (M.A.) from the year 2010 in the subject Chemistry - Physical and Theoretical Chemistry, grade: 1, Annamalai University, course: M.Phil/Ph.D, language: English, abstract: Effect of Electron Beam Irradiation on Electrical Conductivity of PVC (Poly Vinyl Chloride) was carried out. characteristics of PVC changes according to the dosage of electron beam irradiation. That is amorphous nature of PVC changes to crystalline and also conjugate double bond and free radicals are formed due to the degradation. The free radicals formed due to scission process in responsible at higher energy radiation. The electrical conductivity of polyvinyl chloride after irradiation slightly increases with electron beam radiation dose. It is due to increase in crystallinity in the polyvinyl chloride after electron beam irradiation and production of free radicals due to scission or crosslinking in PVC.

The electrical conductivity of polyvinyl chloride was measured as a function of temperature over the range 30-70C before and after irradiation with 1.3-Mev gammas. Three orders of magnitude increase in conductivity were observed for the irradiated specimens after a dose of 4.8 x 10 to the 7th power Rads. Scission of the polymer chain as the dominant effect of the irradiation is postulated. (Author).

Research Paper (postgraduate) from the year 2010 in the subject Chemistry - Physical and Theoretical Chemistry, grade: 1, , course: Master of Philosophy, language: English, abstract: Over the past decade a great deal of information has been published about intrinsically conducting polymers, more commonly known as "synthetic metals". The basic interest comes from the fact that these new materials combine the physical and chemical attributes of plastics with the electrical, electronic, magnetic, and optical properties of metals or semiconductors. Poly (vinyl chloride) (PVC) is extraordinarily useful as a commercial material. Among the thermoplastics, it ranks second only to polyolefins in total worldwide production volume. Remarkably, it has achieved this status despite its molecular instability toward heat, an instability that is much more pronounced than those of all its major competitors. In a technological sense, this difficulty has been overcome to a large degree, for otherwise the usage of PVC would never have reached its current level Commercial interest in PVC was first revealed in a number of patents independently filed in 1928 by Carbide and Carbon Chemical Corporation, Dupont and IG Farben. From the present research studies, it is summarized that the characteristics of poly vinyl chloride [PVC] changes according to the dosage of electron beam irradiation. That is amorphous nature of PVC changes to crystalline and conjugate double bond and free radicals are formed due to the degradation. The free radicals formed due to scission process in responsible at higher energy radiation. The electrical conductivity of polyvinyl chloride after irradiation slightly increases with electron beam radiation dose. It is due to increase in crystallinity in the polyvinyl chloride after electron beam irradiation and production of free radicals due to scission or crosslinking in PVC.

Polyvinyl chloride (PVC) has been around since the late part of the 19th century, although it was not produced commercially until the 1920s; it is the second largest consumed plastic material after polyethylene. PVC products can be rigid or flexible, opaque or transparent, coloured, and insulating or conducting. There is not just one PVC but a whole family of products tailor-made to suit the needs of each application. PVC is extremely cost effective in comparison to other plastics with a high degree of versatility in end-use and processing possibilities, as the reader will note from this book. It is durable, easily maintained, and can be produced in a large range of colours. As a result PVC finds use in an extensive range of applications in virtually all areas of human activity, including medical equipment, construction applications such as flexible roof membranes, pipes and window profiles, toys, automotive parts and electrical cabling. The PVC industry has also started to tackle some of its end-of-life issues. This practical guide provides comprehensive background on the resins and additives, their properties and processing characteristics, as well as discussion of product design and development issues. There have been, and still are, issues and perceptions over environmental and health acceptance covering vinyl chloride monomer, dioxins, phthalate plasticisers, and lead (and cadmium) based heat stabilisers and these are discussed in depth in this book. This book will be of interest to raw materials suppliers and processors or end-users of PVC, as well as anyone with a general interest in this versatile material: resins and additives properties and testing design issues processing, including post processing and assembly property enhancement sustainable development

In this research, the conductive films based on poly (vinyl chloride)/poly (ethylene oxide) (PVC/PEO) with conductive fillers like carbon black, polyaniline and polypyrrole were prepared by solution casting method at the speed of 400 rpm. The composition of 5, 10, 15, 20, 25, 30 wt % of filler loading were incorporated in PVC/PEO: 50/50 blends. The tensile properties, morphology, Fourier Transform Infrared spectroscopy (FTIR) analysis, electrical conductivity and thermogravimetric analysis (TGA) were studied. Poly (vinyl chloride)/poly (ethylene oxide)/carbon black (PVC/PEO/CB) at different compositions were prepared. The tensile strength and modulus of elasticity were increased until up to 25 wt% with the addition of the CB by 25.33% and 16.66% respectively.
