Self-cleaning coating materials have been widely studied in the entire industry such as construction and automobiles. In particular, emulsion polymerization has an easy polymerization method and safe particle dispersibility. In addition, there is an advantage of being able to freely set the coating strength and contact angle characteristics on the surface by controlling the glass transition temperature (Tg) of the polymerized nanoparticles through emulsion polymerization. In this study, nanoparticles were prepared by emulsion-free polymerization, and the Tg of the particles was set differently, coated on slide glass, and the change in anti-wetting properties was observed through changes in surface morphology and roughness and distribution of surface elements. . In order to effectively control the Tg of the particles, the ratio of (MMA, Tg 100℃) and (BA, Tg -60℃) was controlled for the core. When anti-wetting properties were observed through contact angle measurement (CAM).
