Abstract：
Preparation of hydrophobic coatings is still a challenge for researchers in various fields of science. One of the easiest ways consists of the use of special modifiers. However, usually such modifiers are poorly compatible with organic polymeric matrixes, which leads to segregation of modifiers and deterioration of coating properties. In this work, we have synthesized a number of organosilicon copolymers and studied their compatibility with epoxy matrix and hydrophobic efficiency. It was shown that the increase of phenyl-containing units leads to increase of compatibility but decreases hydrophobic efficiency. Addition of small amounts of such modifiers into commercial epoxy paint material can lead to an increase of contact angle of the final coating from 63 to 87° without deterioration of other physico-mechanical properties. These results open new perspectives in preparation of organosilicon hydrophobic modifiers with directed properties for fields of application such as paints and coating materials.
摘要：
疏水性涂层的制备仍然是科学各个领域的研究人员的挑战。最简单的方法之一是使用特殊的修饰符。然而,通常这类改性剂与有机聚合物基质相容性差，这导致改性剂的偏析和涂层性能的恶化。在这项工作中,我们合成了许多有机硅共聚物，并研究了它们与环氧基体的相容性和疏水效率。结果表明，含苯基单元的增加会导致相容性增加，但会降低疏水效率。向商业环氧漆材料中添加少量的此类改性剂可导致最终涂层的接触角从63°增加到87°,而不会劣化其它物理机械性能。这些结果为制备有机硅疏水性改性剂开辟了新的前景，这些改性剂具有针对诸如油漆和涂料之类的应用领域的定向性能。
