表面活性劑是否對斥水性土壤的潤濕性有影響?——結論、致謝!

結論


不像人工創造的穩定的驅蟲表面或多孔 介質,拒水土壤表現出潤濕動力學,由此 最初疏水的土壤隨著時間的推移變得親水 與水接觸時。 初始潤濕動力學 排斥土壤通常歸因于 固液界面能 (γSL),或液汽界面能 (γLV) 的降低,或兩者兼而有之。 γLV 的減少 建議是由于土壤表面溶解 活性有機化合物進入與水接觸的水中 土壤。 在這項研究中,我們測試了土傳表面的影響 潤濕動力學的活性物質,并發現,與廣為接受的范式相反,土壤釋放表面 活性化合物不會加速潤濕過程。 因此很明顯,固體界面能的變化 表面(γSL 或 γSV),而不是液汽 表面 (γLV) 必須在驅動不穩定排斥性土壤的潤濕動力學方面起主導作用。
