表面活性剂是否对斥水性土壤的润湿性有影响？——结论、致谢！

结论
不像人工创造的稳定的驱虫表面或多孔 介质，拒水土壤表现出润湿动力学，由此 最初疏水的土壤随着时间的推移变得亲水 与水接触时。 初始润湿动力学 排斥土壤通常归因于 固液界面能 (γSL)，或液汽界面能 (γLV) 的降低，或两者兼而有之。 γLV 的减少 建议是由于土壤表面溶解 活性有机化合物进入与水接触的水中 土壤。 在这项研究中，91视频播放器测试了土传表面的影响 润湿动力学的活性物质，并发现，与广为接受的范式相反，土壤释放表面 活性化合物不会加速润湿过程。 因此很明显，固体界面能的变化 表面（γSL 或 γSV），而不是液汽 表面 (γLV) 必须在驱动不稳定排斥性土壤的润湿动力学方面起主导作用。
