Disclosed herein are gemini surfactants, and methods for making and using these gemini surfactants. These gemini surfactants may be incorporated in paints and coatings to provide hydrophilic and/or self-cleaning properties. Surfactants are compounds composed of both hydrophilic and hydrophobic or lipophilic groups. In view of their dual hydrophilic and hydrophobic nature, surfactants tend to concentrate at the interfaces of aqueous mixtures; the hydrophilic part of the surfactant orients itself towards the aqueous phase and the hydrophobic part orients itself away from the aqueous phase.
本文披露了双子表面活性剂,以及制备和使用这些双子表面活性剂的方法。这些双子表面活性剂可以被用于涂料中,以提供亲
水性和/或自洁性能。表面活性剂是由亲
水性和疏
水性或亲脂性基团组成的化合物。由于它们既具有亲
水性又具有疏
水性的特性,表面活性剂倾向于在
水性混合物的界面处聚集;表面活性剂的亲
水部分朝向
水相,而疏
水部分朝向远离
水相的方向排列。
