中文摘要：

主要研究了自行合成的3种吸油烟材料以及商用G-1651树脂表面的吸附自由能特殊能分量对其表面吸附油烟性能的影响。用反相气相色谱IGC测定了自行合成的聚丙烯酸异丁酯（PIBA）、聚甲基丙烯酸甲酯-甲基丙烯酸丁酯（PMMA-BMA）和聚甲基丙烯酸十二酯-丙烯酸-2-乙基己酯（PLMA-2-EHMA）3种吸油烟树脂以及商用G-1651树脂表面的吸附自由能特殊能分量。实验结果表明,4种聚合物的吸附自由能特殊能分量大小如下：G-1651树脂PIBA〉PMMA-BMA〉PLMA-2-EHMA。4种树脂吸附油烟能力的大小顺序与其极性大小顺序恰恰相反,即PLMA-2-EHMA〉PMMA-BMA〉PIBA〉G-1651树脂。这是由于油烟中的主要成分都是非极性或弱极性的,因此,材料表面的吸附自由能特殊能分量值越大,吸附质与吸油烟材料表面形成的吸附越牢,吸油烟材料吸附油烟的能力越强。

英文摘要：

The relationship of specific component of polymeric resins with surface polarity of polymeric resins on adsorption capacity of cooking oil were investigated.The specific components of polymeric resins PIBA,PMMA-BMA,PLMA-2-EHMA and G-1651 resin were measured with inverse gas chromatography（IGC）.The results of IGC showed that specific components were negative,which meant that this adsorption was spontaneous.The specific components of four resins followed the order：G-1651 resinPIBA〉PMMA-BMA〉PLMA-2-EHMA.The order of adsorption capacity for oil fume was PLMA-2-EHMA 〉 PMMA-BMA 〉 PIBA 〉G-1651 resin,which was contrary to the polarity of resins.The polarity of a polymeric resin showed a strong influence on the adsorption capacity for cooking oil.Because most components of oil fume were non-polar or weakly polar,the higher the specific component,the stronger the adsorption capacity of resin for oil fume.
