Synthesis and Property Analysis of Poly-Acryl-amide (Pam)/poly-Vinyl-alcohol (PVA) Blend Thin Films

We present a study of variation in the dielectric properties of polymeric blend films of polyacrylamide (PAM)/Polyvinylalcohol (PVA). Initially, the PAM and PVA were used to obtain apolymeric blend solution in distilled water. Preparation of blended films was conducted by a drying process. Films of pure PAM, pure PVA and blend films (w/w%) were characterizedby X-ray diffraction (XRD) and scanning electron microscopy (SEM). The characterizations revealed proper trends for the films depending upon weight percent (PAM: PVA: 20:80, 40:60, 60:40, 80:20). Variations in their dielectric property were investigated by use of a LCR (inductor capacitor resistor) meter.
