Thermal analyses, and X-ray diffrac-tion (XRD) were employed to characterize and reveal the miscibility map and the structural properties of such blend system. In the present work, blends of PVA/HPC of com-positions (100/0, 90/10, 75/25, 50/50, 25/75, and 0/100 wt/wt%) were prepared to be used as bio-equivalent materials. Blending poly(vinyl alcohol) (PVA) with a poten-tially useful natural biopolymers such as hy-droxypropyl cellulose (HPC) seems to be an in-teresting way of preparing a polymeric blends. Polymers and polymeric composites have stea-dily reflected their importance in our daily life. The measured Ac conductivity shows how the conductivity varies in these films with the presence of different amount of CuSO4 in these films. The variation in the transmittance has been studied with the help of recorded UV-Vis spectra and hence the optical band gap present in the samples is also calculated. Recorded FT-IR spectra give information about the stretching and bending of the characteristic absorption bands in these films.

Micro-structural parameters were computed using an in-house program employing XRD data. XRD patterns of these films recorded at room temperature show the increase in amorph-ousity of the matrix with the increase in the concentration of CuSO4 in polymer composites. These films were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Ultraviolet-Visible absorbance spectroscopy (UV-Vis) and Ac conductivity measurement studies.

ABSTRACT RESEARCH ARTICLEĪ series of polyvinyl alcohol/polyvinyl pyrrolidone polymer composite films doped with different amount of cupric sulphate (CuSO4) were prepared by means of solution casting technique. In this study as well, a (PVA-PVP-Ag) nano polymer composite solution has been prepared where a test of the bacteria (E.Coli, Proteus) sensitivity has conducted for this solution, in addition the practical results have exhibited that mentioned nano polymer composite solution is highly effective in terminating and constraining the stated bacteria. The differential scanning calorimetric (DSC) test has showed that the glass transition of the polymer blends films in which increases in most of the weight ratios of the polymer blend compared with pure (PVA) polymer film while decreases in weight ratios ((,, ) wt%) of the polymer blend compared with pure (PVA) polymer film with absent of the glass transition at the weight ratio ( wt%) for the polymer blend, also, the crystalline melting point showed irregular behavior compared with pure (PVA) polymer film by increasing the weight ratio of the (PVP) polymer with absent of the crystalline melting point at the weight ratio ( wt%) for the polymer blend.

The effect of the weight ratio of the polymer blend on the thermal properties of polymer blends films have been studied, the practical results have shown that the thermal conductivity coefficient of polymer blends films behaves irregularly compared with pure (PVA) polymer film by increasing the weight ratio of the (PVP) polymer.

In this study pure (PVA) polymer film and films of polymer blends at weight ratios ((,, , ),, ,, ,, ) wt%) preparation using the casting method.
