Structural, Optical and Mechanical properties of PVC∕PMMA Polymer Blend by Spectroscopic Techniques

摘要

PVC∕PMMA polymer blends were characterized by Fourier Transform Infrared Spectroscopy (FTIR), UV‐VIS Spectroscopy and mechanical analysis. The changes in mechanical properties are reflected by the changes in the IR spectrum. The mechanical properties of such poly blends revealed a substantial increase in Young's modulus and ultimate tensile strength after initial drop at 10% of PMMA. Optical properties such as the absorption coefficient, optical (Direct∕Indirect) energy gap were calculated. The effects of different blending percentage on these parameters have been discussed and their results are co‐related with IR study.
