Abstract
The aim of this work is to study the effect of the exposure of a polycarbonate (PC) to the simultaneous effects of heat and ultraviolet radiation. PC is an amorphous polymer widespread in commerce. Transparency, impact resistance, and low density are just a few of the many intriguing properties of this material, this is why it is used like a material of greenhouses, windows of headlights, body parts, anti-shock windows, anti-vandal panes. However, long exposure to the heat and radiation makes it fragile and translucent. In this study, we have submitted the PC to the simultaneous action of ultraviolet (UV) with wavelength of 253nm combined to temperature of 120 ℃ for 72, 144 and 2016 h. The effects were highlighted by the physico-chemical analyzes and mechanical tests. Thus, the modification of chemical bonds was revealed by spectrometry by spectroscopy FTIR and changes of the mechanical properties was revealed by the compression and traction tests.
