The resistance of wood fibers-poly(vinyl chloride) composites to UV-irradiation (in English)

Polimery 2008, No 1, 60


Summary

Wood fibers-poly(vinyl chloride) (WF-PVC) composite and pure poly(vinyl chloride) samples, prepared by extrusion, were exposed to short wavelength UV-irradiation (λ=253.7nm). Scanning Electron Microscopy (SEM) micrographs shows heterogeneity of WF-PVC composite but the effect of UV-irradiation on surface morphology of sample is negligible. The course of photochemical reactions occurring in samples studied has been monitored by attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy. The results obtained indicate the better photochemical stability of WF-PVC comparing to virgin PVC.


Key words: wood fibers-poly(vinyl chloride) composites, UV-irradiation, ATR-FTIR spectroscopy, surface morphology
