Abstract
Abstract
The induced photo degradation of poly epoxy films in air was investigated in the presence and absence of di-benzoylperoxide (BPO)(photosensitizer) by accelerated weathering tester. The addition (0.1 wt%) of BPO to poly epoxy films (25μm in thickness)increases the photo degradation of the poly epoxy films. The photodegradation rate was followed by increase in carbonyl absorbance of polymers using I.R. spectra.
According to the spectra results, the induced photo degradation mechanisms of poly epoxy films were suggested under the experimental conditions employedusing Uv-radiation at λ = 313 nm light intensity 3.49∗10−5einsteins.dm−3.S−1 at temperature 45°C. The biodegradability of photodegradable polymers has been also studied using different bacteria. This type of bacteria is known to be capable of utilizing the degraded polymers.
