【摘要】 利用反气相色谱技术(IGC)对用空气等离子处理后的Kevlar-49(聚对苯二甲酰对苯二胺)纤维进行了表面特性表征。实验结果表明经处理后纤维对正烷烃的吸附焓和吸附熵均有增加,纤维表面能的色散分量明显降低,与酸性或碱性探针的相互作用则有了明显提高。更多还原

【Abstract】 Inverse Gas Chromatography (IGC) was used to characterize the surface property of kevlar49 fibers. It was found thatcompared with untreated fibers, enthalpy and entropy of nalkane absorption on the surface of plasma treated fibers increased, while the dispersive component of fiber surface energy evidently decreased, and the interaction with acid and basic probes strengthened.更多还原
