摘　　要：通过户外曝晒自然老化和室内人工加速老化降解实验研究了XUS系列煤基光敏剂对薄膜光降解性能的影响。结果表明煤基光敏剂对薄膜的光降解有较好的催化作用,三种煤基光敏剂的催化活性顺序为:XUS-TF>XUS-H>XUS-T。改变煤基光敏剂的类型和添加量可以调节薄膜的光降解速度。煤基光敏剂的光催化活性与煤结构有关。The effect of XUS coal - based photosensitizers on degradable properties of films have been studied by accelerated UV chamber exposure test and natural exposure test. The coal - based photosensitizers are effective on catalysis photodegradation for degradable films, and the order of photocatalytic efficiency of the coal - based photosensitizers is XUS - TF 〉 XUS - H 〉 XUS - T. Changing type and content of the photosensitizers in films can control the photodegradation rate of films. The photocatalytic activity of coal - based photosensitizers is related to the structure of coal.
