Abstract

A comparison was made of the physicochemical and physicomechanical properties of films and coatings based on latex polyacrylates before and after their modification water-soluble tetrasodium salt of copper–phthalocyanine–tetrasulfonic acid. Using atomic-force microscopy methods, Raman spectroscopy and thermogravimetry showed that phthalocyanine is localized on the surface of latex particles in the interparticle regions of films and coatings due to interaction between phthalocyanine and polyacrylate. Using the method of dynamic mechanical relaxation spectroscopy, an increase in the intensity of α-relaxation was established upon modification of polymer films as a result of disruption of the relaxation homogeneity of the polymer material. Adhesion of unmodified and modified polymers to a metal substrate causes a decrease in the intensity of α-relaxation and frequency of the oscillatory process. Modification of the polymer and its adhesion to the substrate are accompanied by a decrease in its elasticity.

水溶性四硫化酞菁对不同弹性聚丙烯酸酯薄膜及薄膜和涂层的物理化学物理机械性能的影响

比较了基于乳胶聚丙烯酸酯的薄膜和涂层在铜酞菁-四磺酸水溶性四钠盐改性前后的物理化学和物理机械特性。使用原子力显微镜方法、拉曼光谱和热重测定法表明，由于酞菁和聚丙烯酸酯之间的相互作用，酞菁被定位在薄膜和涂层的颗粒间区域的胶乳颗粒表面。利用动态机械松弛光谱法，确定了聚合物薄膜改性后，由于聚合物材料的松弛均匀性被破坏，α-松弛强度增加。未改性和改性聚合物粘附到金属基底上会导致 α 松弛强度和振荡频率降低。聚合物的改性及其与基底的粘附会降低其弹性。
