Study of structural and thermal properties of electron beam irradiated polymethylmethacrylate/bisphenol‐A‐polycarbonate blends

Abstract

Polymethylmethacrylate (PMMA)and bisphenol-A-polycarbonate (PC) polymer blends are prepared by solution casting technique using tetrahydrofuran as a solvent. The structural properties of the polymer blends before and after they had been irradiated to electron beam accelerator was investigated by color strength, scanning electron microscopy (SEM), and FTIR spectroscopy. The thermal properties such as TGA and DSC were investigated. The TGA thermograms showed that the thermal stability of the unirradiated polymer blends PMMA/PC increases with increasing the ratios of PC component in the blend. Also, it was found that the pres-ence of PC polymer in the blend affords protection against radiation degradation and improves their thermal stability. The DSC scans show a single T g intermediate between PMMA and PC indicate the existence of specific interactions between PMMA and PC polymers in the blend. An intimate blends are reflected by substantial shifts in the frequencies of the PMMA and PC C¼ ¼O vibration obtained by FTIR. SEM confirms the homogeneity of the blend.

“…Polymer blending has always been considered as an economical way to develop new polymeric materials whose physical properties may not only be superior to one of the component polymers but also tunable as a function of the blend composition [1][2][3]. The blends of PC and PMMA have been received considerable research attention [4][5][6] because of their potential applications as gas separation membranes, pearl materials, discs substrates in optical data storage medium, and packaging materials [7,8].…”
