| Abstract: | Photo-degradabilities, structures and degradati containing 35% of corn starch were investigated by using results show that the degradation rate could be regulated on principles of photo-biodegradable plastic films FTIR, DSC, GPC and GC-MS. The experiment through different sensitizer and its content. Iron stearic and cerium stearic have the same photosensitive action on the film, which is better than that of diethyl iron dithiocarbamate. A suitable sensitizer concentration is about 0. 2% -0. 3%. With increasing the degree of degradation, the carbonyl index and crystallinity of polyethylene in films increase, but the melting point and relative molecular weight of polyethylene in films decrease. Some low molecular weight products, such as alkyl hydrocarbon, ketone, aldehyde, ester, carboxylic acid and binary carboxylic acid were detected in the degraded films. |
