摘　　要：从吸附的基本概念和分类入手,判断了网状聚氨酯(PUR)泡沫吸附汽油的吸附类型,指出该吸附不仅发生在PUR表面,而且还在细孔内发生毛细凝聚现象,并提出其吸附过程分为三个阶段;在对PUR和汽油的极性分析后,进一步对吸附中的范德华作用进行了探讨,得出了色散力为主要吸附力的结论;而后阐述了细孔内毛细管作用及其成因;最后,对该吸附的势能进行了分析,得出了PUR泡沫吸附汽油的总势能公式。From basic concepts and classification of adsorption, adsorption gasoline type of reticular polyurethane foam was judged, the phenomenon that the adsorption not only occured on polyurethane ＇s surface, but also capillary condensation happened in the fine hole was pointed out.The adsorption process was divided into three stages was putting forward.After analysis on polyurethane and gasoline＇s polarity, van der Waals interaction of adsorption was further discussed, reaching a conclusion that dispersion force was the main adsorption force.And then fine hole capillary action and its causes were expounded.At last, potential energy of adsorption was analyzed, potential energy formula of adsorption gasoline by polyurethane foam was obtained.
