“…Recently, inorganic-organic hybrid materials have attracted increasing interest from materials scientists due to the combination of the advantages of both the inorganic and organic components [1][2][3][4][5][6][7]. They can be applied in many fields such as functional and protective coatings, catalysis, optics, electronics, sensors, medicine and biotechnology [1][2][3][4][5][6][7].…”

The trilayer core-shell polysilsesquioxane/polyacrylate/poly(fluorinated acrylate) (PSQ/PA/PFA) hybrid latex particles are successfully prepared, using functional PSQ latex particles with reactive methacryloxypropyl groups synthesized by the hydrolysis and polycondensation of (3-methacryloxypropyl)trimethoxysilane in the presence of a reactive emulsifier as seeds. Transmission electron microscopy (TEM), scanning electron microscopy (SEM) and dynamic light scattering (DLS) confirm that the resultant hybrid latex particles have evident trilayer core-shell structure and a narrow size distribution. The Fourier transform infrared (FTIR) spectra show that fluorinated acrylate monomers are effectively involved in the emulsion copolymerization and formed the fluorine-containing hybrid latex particles. XPS analysis of the obtained hybrid latex film reveals that the intensity of fluorine signal in the film-air interface is higher than that in the film-glass interface. In addition, compared with pure polyacrylate latex film, the obtained fluorine-containing hybrid film shows higher hydrophobicity and thermal stability, and lower surface free energy.

“…A frequent polymer–TiO 2 synthesis route is in situ emulsion polymerization, which leads to a good dispersion of the inorganic phase [27–29]. Titanium dioxide encapsulation in polymer, often results in a core–shell morphology [30]. On the other hand, polymers may be used as a specific reactor for preparation of TiO 2 particles of dimensions mostly useful for specific applications [e.g., 31–33].…”

Nanostructured polymer–titanium composites and titanium oxide through polymer swelling in titania precursor

et al. 2012

Polymer (XAD7HP)/Ti4+ nanocomposites were prepared through the swelling of polymer in titanium (IV) ethoxide as a titanium dioxide precursor. The nanocomposite beads exhibit relatively high porosity different than the porosity of the initial polymer. Thermal treatment of composite particles up to 200 °C in vacuum causes the change of their internal structure. At higher temperature, the components of composite become more tightly packed. Calcination at 600 °C and total removal of polymer produce spherically shaped TiO2 condensed phase as determined by XRD. Thermally treated composites show the substantial change of pore dimensions within micro- and mesopores. The presence of micropores and their transformation during thermal processing was studied successfully by positron annihilation lifetime spectroscopy (PALS). The results derived from PALS experiment were compared with those obtaining from low-temperature nitrogen adsorption data.
