2.
The effects of cationic Gemini surfactants on the wettability of solid surface were examined and their action mechanisms were discussed.
研究了阳离子双子表面活性剂对固体表面润湿性的影响,并从机理上进行了探讨, 结果表明,与普通表面活性剂相比,阳离子双子表面活性剂在很低浓度时就能将油湿的固体表面转化为强水湿表面,并且不会改变水湿表面的润湿性;另外,对联接基长度相同但是疏水烷基链长度不同的双子表面活性剂对固体表面的润湿性影响进行了考察,结果发现疏水烷基链短的双子表面活性剂较疏水烷基链长度长的双子表面活性剂更能显著影响固体表面的润湿性。
