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
