    摘要
  • 摘要: 利用座滴法和电泳法研究了阳离子Gemini表面活性剂C12-m-C12·2Br-(m=4、6、8、10)在煤沥青表面的润湿性质及吸附机理。结果表明, 表面张力均随表面活性剂浓度的增大而减小, 超过临界胶束浓度(CMC)后趋于平稳, 接触角θ和铺展系数S的变化趋势与表面张力类似; 在所研究浓度范围内,C12-10-C12型表面活性剂的γlg~cosθ曲线符合Zisman理论, 且侵湿功(Wi)与表面张力也呈线性关系; 煤沥青表面的Zeta电位随表面活性剂浓度的增加从负电变为正电,最后趋于平稳, 且零电位对应的浓度比CMC至少低一个数量级; C12-8-C12型Gemini表面活性剂能显著改变煤沥青表面的润湿性. 由Gemini表面活性剂在煤沥青表面润湿结果及Zeta电位可以看出, C12-m-C12型Gemini表面活性剂在煤沥青表面的润湿是静电作用和范德华吸附共同作用的结果; 润湿过程可分为三个阶段。
    Abstract: Wettability and adsorptive mechanism of coal tar pitch by aqueous solutions of cationic surfactant (C12-m-C12·2Br-, m=4, 6, 8, 10)were investigated by the sessile drop analysis and electrophoresis. The results indicate that the surface tension decreases with increasing surfactant concentration up to the CMC (critical micelle concentration) of the surfactant solution, which θ and S have the similar trend with surface tension. Within the whole range of concentration, the Zisman theory is in accordance with the wettability on the coal tar pitch when spacer chain length value reaches to 10. Meanwhile, there is a liner dependence between adhesion tension (γlgcosθ) and surface tension (γlg). Zeta potential on the surface of the coal tar pitch increases with the increasing surfactant concentration from negative to positive, and finally levels off. And the concentration of the zero potential is lower than CMC at least an order of magnitude. C12-8-C12 Gemini surfactants can significantly change the wettability on the surface of the coal tar pitch. According to the wetting data and Zeta potential of Gemini surfactant on coal tar pitch, it can be inferred that wetting is a concerted action result of electrostatic interaction and van der waals adsorption. Therefore, wetting process can be generally divided into three phases.
