Abstract:
The purpose of this research was to study the structural and physical properties of
polyvinyl alcohol (PV A) thin film. The thin films morphology was characterized by
scanning electron microscope (SEM) and Fourier Transform Infrared (FTIR)
spectroscopy. For SEM, the morphology of PV A powders and thin film has being
measured. After that, we were also being evaluated powder for comparison to the thin
film. FTIR is most useful for identifying chemicals. FTIR spectra of the thin film
indicated complete esterification of the free carboxylic groups of distilled water. The
PV A powder was also measured by using FTIR as comparison to the thin film. The
mechanical properties of the thin films were characterized by tensile tests and
hardness test. The comparison of tensile test and hardness is indicated with
commercial plastic. The comparison of the width of thin film, the tensile give
different reading. When width increases, the tensile strength also increases. The
hardness is increase when width increase and we have found that the thin film is
smooth than commercial plastic. PV A structural and physical properties suggested
being test by various instruments like XRD, XRD, hemocompatibility test, and
viscosity measurement, DSC thermogram characterization to get more accurate result
and to know more application of it. The experimental results indicated that the PV A
thin film could be tried for various applications.
