The TiO₂/P (MMA/BA/MAA) nanocomposite latex are successfully prepared by miniemulsion polymerization.

TiO₂ nanoparticles are monodispersed in the latex particles, almost no aggregation occurs during the film formation process.

The thermal properties of the nanocomposites are enhanced significantly.

The nanocomposite film possesses excellent UV-shielding capacity and exhibits high visible transparency.
