Herein, environmentally friendly surfactants based on new silanols as substitutes for the isoelectronic phosphonates were explored. Surface tensions of aqueous solutions are significantly reduced, particularly with those silanols that feature a high ratio of organic moiety to silanol. Besides their use as surfactants, their potential as coating agents for hydrophilic oxide surfaces was investigated
在此,探索了基于新型硅烷醇作为等电子膦酸酯的替代物的环保型表面活性剂。水溶液的表面张力显着降低,尤其是那些有机部分与硅烷醇比例高的硅烷醇。除了用作表面活性剂外,还以玻璃基材为例研究了它们作为亲水性氧化物表面涂料的潜力。在含硅烷醇的固态片状结构中,存在双层,其中片状间距随烷基链长而变化。
