中文摘要：

研究了共聚物的加入对含氟/无氟丙烯酸酯乳液共混体系相容性、膜表面性能和梯度结构的影响。通过表面能、附着力、DSC和膜的断面SEM-EDX表征发现：加入共聚物后,特别是含氟/无氟组成对称的共聚物能较好地改善体系的相分离现象;共聚物中含氟组分高有利于膜的梯度结构的形成;膜的表面性能受共聚物的影响较小,热处理使膜与空气界面富集含氟组分,而膜与玻璃界面被不含氟组分占据,膜在玻璃基材上的附着力达到2级。

英文摘要：

The effects of adding the fluorinated acrylate copolymer in fluorinated/non-fluorinated polyacrylate latex blend on the surface property,gradient structure and compatibility of the blend film were studied by surface free energy testing,adhesion test,DSC and SEM-EDX.The results showed that the compatibility of the blend system was improved after adding the copolymers.The increasing of the fluorine content of copolymer was beneficial to the formation of gradient structure.The copolymer had little influence on the surface property of the films.After heat treatment,the fluorinated polyacrylates were rich on the film-air interface and the acrylate copolymers were rich on the film-glass interface of the blend films,the adhesive attraction of films to glass was reached grade 2.
