Nanocomposite microspheres were successfully prepared by grafting TiO2particles to microPCMs by chemical reaction method. The effects of modification of nano TiO2particles, adding time of TiO2dispersion and the amount of TiO2on the surface morphology were investigated. The results indicated that the optional method is adding the TiO2dispersion as soon as all the prepolymer was added to the reaction system, and the optional mass ratio of TiO2to microPCMS is 10wt%.

For the first time, hydrophobic MMA floor coatings were prepared based on the fluorine-containing methacrylic ester copolymers and applied as a new kind of anti-slip flooring coatings. The composition of the synthesized copolymers was characterized by FT-IR and 1H-NMR. The prepared hydrophobic MMA floor coatings were analyzed for their coating properties. The hydrophobic properties of the coatings were characterized by static and dynamic contact angles and X-ray photo-electronic spectroscopy (XPS). Results show that the newly prepared floor coatings are easy to apply and have excellent mechanical and hydrophobic properties, which indicates that the hydrophobic MMA floor coatings have great potential applications in anti-slip flooring coatings.
