摘要

Developing degradable films is an important means for resolving the problem of film pollution; however, in recent years,there have been only few studies related to the thermal analysis of degradable plastic films. This research detailed the composition and pyrolysis of one kind of ordinary and three kinds of degradable plastic films using the differential thermal analysis (DTA) technique. The results showed that degradable films and ordinary film had similar DTA curves, which reflected their similar compositions; however, small differences were measured, which were due to the added constituents of the degradable films. The pyrolysis reaction orders of each film were about 0.93. The pyrolysis activation energies and pre-exponential factors followed the order of ordinary film ＞ photodegradable film ＞ photodegradable calcium carbonate film ＞ biodegradable film. The results of this research laid the foundation for new theories for harnessing soil pollution caused by plastic films.
