Film forming hybrid acrylic/ZnO latexes with excellent UV absorption capacity

The synthesis of monodispersed M-CeO2/SiO2nanoparticles and formation of UV absorption coatings with them

“…9 Compared with organic UV absorbers that may release environmental pollutants, such as volatile organic compounds (VOC), inorganic nanoparticles such as TiO 2 , ZnO and CeO 2 seem to be better choices. [10][11][12][13][14] Among the numerous UV absorbers, ceria nanoparticles are ideal candidates due to their excellent UV absorption ability, visible light transparency and lower light refractive index. [15][16][17][18] Several studies have been published on the incorporation of CeO 2 nanoparticles into polymer latex to shield UV light.…”

Waterborne Acrylic/CeO2 Nanocomposites for UV Blocking Clear Coats

“…ZnO nanoparticles was also synthesized following the same seeded semibatch polymerization approach as described in Section 2 [34]. The morphology obtained in the final hybrid films was different to that obtained for the CeO 2 hybrid films.…”

“…The designed strategy opens the possibility to encapsulate other nanoparticles and extend the application region. The incorporation of hydrophobically modified ZnO nanoparticles has also been tested, providing film forming hybrid latexes with improved UV absorption capacity [73]. Moreover, with the incorporation of a fluorinated monomer to the acrylic/ZnO hybrid system, Figure 6.…”

“…All of them absorb radiation around 400 nm [26] and posses a band gap energy of around 3 eV [27], which makes them good candidates for UV absorption purposes. There are some works in which TiO 2 [28][29][30][31] and ZnO [32][33][34][35] nanoparticles have been incorporated into polymer matrixes to improve the UV absorbance capacity of the coating. Nevertheless, the photocatalytic activity of CeO 2 nanoparticles is lower than that of TiO 2 and ZnO [36], which might prevent a faster degradation of the acrylic coatings due to the presence of the metal oxide, making CeO 2 nanoparticles ideal candidates for their incorporation into waterborne acrylic coatings.…”

Photocatalytic and magnetic titanium dioxide/polystyrene/magnetite composite hybrid polymer particles

“…Miniemulsion polymerization has been used to synthesize a wide range of polymer‐inorganic colloidal materials . In these works, the inorganic particles are placed either inside the polymer particles or at the surface of the particles . In the latter case, the inorganic particles can be used to provide colloidal stabilization to the system through a Pickering stabilization mechanism.…”
