摘要: 以一步乳液聚合法制备单分散的聚(苯乙烯-甲基丙烯酸甲酯-丙烯酸)乳胶微球,通过控制表面活性剂十二烷基苯磺酸钠用量来调控乳胶微球粒径的大小,采用竖直沉积法将乳胶微球组装成光子晶体薄膜,继而用疏水改性剂对光子晶体薄膜表面进行改性。利用扫描电镜、紫外-可见分光光谱仪和接触角测量仪对样品进行了表征。结果表明:合成的乳胶微球的单分散性优异;不同带隙的光子晶体薄膜的颜色可实现全可见光的覆盖;疏水性光子晶体薄膜的疏水性能良好,其接触角在130°以上。

Abstract: The monodispersing poly(styrene-methyl methacrylate-acrylic acid) latex microspheres were prepared by one-step emulsion polymerization.Diameter of the latex microspheres can be controlled by the dosage of surfactant sodium dodecylbenzene sulfonate.By vertical deposition method,latex microspheres with different diameter were self-assembled to form photonic crystal (PC) films.Finally,the surface of PC films was modified by hydrophobic agent.The products were characterized by means of scanning electron microscopy,UV-Vis spectrophotometer and contact angle measurement.Experimental results showed that the latex microspheres possess excellent monodispersity.The color for the different band gaps of PC films covers that of whole visible light.The performance of hydrophobic PC films is outstanding;its contact angle is more than 130°.

Key words: surfactant, hydrophobic modification, photonic crystal, monodispersity, latex microspheres, contact angle
