    A study of structural and physical properties of pva/tio2 composite polymer
    (Terengganu: Universiti Malaysia Terengganu, 2009) Mohd Khazimie Mahsan
    Polyvinyl alcohol (PV A) is one of the prom1smg representatives of polymeric material. There are numerous proposals for its application in electronics, as well as packaging textiles and food products, due to its high clarity, lack of charge densities properties and excellent durability. The application of polymer especially polyvinyl alcohol (PV A) has generated much interest in various industries. In this polymer study, the main purpose of this study is to measure and understand the structural and physical properties and also the characterization of PV A/Ti02 composite polymer. In this research, properties of PV A/Ti02 composite polymers have been studied by several techniques. The samples were prepared by using solution casting technique. Then after that was the measurement to reveal the surface morphology of PV A/Ti02 composite polymer thin film. The image of the both PV A surface has been carried out by Scanning Electron Microscope (SEM). Infrared spectrometer was used to demonstrate the structure of PV A and whether the complexion that occur in the composite polymer structure. The result showed the bond group of PV A in range between 500 cm-1 and 4000 cm-1 • Then the composite also had been studied of their conductivity by using Electrochemical Impedance Spectroscopy (EIS). The highest conductivity of the composite had been known from this study which is 2.66x 10- 9 S cm-1.
