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。
The effect of cationic gemini surfactant on the wettability of solid surface was studied and the mechanism was discussed. The results showed that the cationic gemini surfactant could wet the oil at a very low concentration compared with the conventional surfactant Solid surface to a strongly wet surface without changing the wettability of the wet surface; in addition, the influence of the gemini surfactant on the solid surface for gemini surfactants with the same length of the linker but different hydrophobic alkyl chains The investigation revealed that gemini surfactants with shorter hydrophobic alkyl chains have a more pronounced effect on the wettability of solid surfaces than gemini surfactants with long hydrophobic alkyl chains.
