摘要
基于溶液聚合的方法,将合成的具有"树枝状"结构含氟单体与其他丙烯酸类单体进行共聚反应,制备出了一种具有"树枝状"结构的短氟碳链含氟聚合物。考察了含氟单体用量及含氟单体的氟含量对水接触角的影响;系统探究了"树枝状"结构对聚合物材料表面接触角的影响。结果表明,与"伞形"和线型短氟碳链含氟聚合物相比,"树枝状"结构的含氟聚合物的表面接触角有明显提高,可高达111.3°,X射线光电子能谱测试表明其表面的含氟量亦从18.4%增加到了26.9%;同时材料表面拒水性能得到有效提高。
Firstly, The polymer was polymerized with other acrylate monomer and the short fluorocarbon chain monomer with "dendritic" structure based on solution polymeriz ation. The influence of the content of fluorine-containing monomer and the fluo rine content of fluorine-containing monomer on the water contact angle was investigated. And the influence of "dendritic" structure on the contact angle of surface was explored as well. Compared with "umbrella" and linear fluorocar bon polymers,the results show that the surface contact angle of "dendritic" fluoropolymers is obviously improved, which can be as high as 111.3°. Meanwhile, XPS test shows that the fluorine content of the surface increases from 18.4% to 26.9%;and the water repellency of the surface of the material is improved effectively.
