WebMar 20, 2024 · The aim of this paper is to characterize the thermal aging effect near the glass transition temperature of polycarbonate (PC) at different hold time. For this, the physicochemical characterization and mechanical behavior of PC after annealing at 120 °C for 72, 144 and 216 h were investigated. WebFourier Transform-Infrared Spectroscopy (FTIR) is a reliable and cost-effective analytical tool for identification of polymers and assessment of the quality of plastic materials. …

WebIt was concluded that the most influential parameter for the permeation is the diffusion coefficient of the gases. The permeability and selectivity decrease as the operating pressure and PEG content are increased. Furthermore, the results showed that the addition of 5 wt% of PEG into PC increases the CO2/CH4 selectivity from 26.6 +/- 0.99 to 40 ...
