The cross-linking reaction of a TiO(2)-polymer composite (TPC) dielectric with poly(4-vinyl phenol) (PVP), a TiO(2) precursor, and poly(melamine-co-formaldehyde) is demonstrated: We suggest that the dense chemical structure of TPC is caused by the alkoxyl group of the PVP cross-linker, poly(melamine-co-formaldehyde) methylated/butylated, reacted with the hydroxyl group of the PVP and the ligands of the TiO(2) precursor.

Metasurfaces, 2D arrays of nanostructures, have gained significant attention in recent years due to their ability to manipulate light at the subwavelength scale. Their diverse applications range from advanced optical devices to sensing and imaging technologies. However, the mass production of dielectric metasurfaces with tailored properties for visible light has remained a challenge.

We present a novel approach for the preparation of polymer-TiO₂ composite microgels. These microgels were prepared by the in situ hydrolysis and condensation of titanium tetrabutoxide (TBOT) in a mixed ethanol/acetonitrile solvent system, using poly(styrene---isopropylacrylamide)/poly(-isopropylacrylamide--methacrylic acid) (P(St-NIPAM/P(NIPAM--MAA)) as the core component. Silver nanoparticles (AgNPs) were controllably loaded onto the polymer-TiO₂ composite microgels through the reduction of an ammoniacal silver solution in ethanol catalyzed by NaOH.

Multifunctional superhydrophobic nanocomposite surfaces based on photocatalytic materials, such as fluorosilane modified TiO2, have generated significant research interest. However, there are two challenges to forming such multifunctional surfaces with stable superhydrophobic properties: the photocatalytic oxidation of the hydrophobic functional groups, which leads to the permanent loss of superhydrophobicity, as well as the photoinduced reversible hydrolysis of the catalytic particle surface. Herein, we report a simple and inexpensive template lamination method to fabricate multifunctional TiO2-high-density polyethylene (HDPE) nanocomposite surfaces exhibiting superhydrophobicity, UV-induced reversible wettability, and self-cleaning properties.

Composite films of nanosized TiO2 particles, which contained rutile as the only detected crystal modification, and poly(vinyl alcohol), poly(vinyl pyrrolidone) or poly(4-vinylpyridine) were prepared from aqueous dispersions. During exposure to UV irradiation the nanocomposites comprising poly(vinyl alcohol) or poly(vinyl pyrrolidone) turned blue as a consequence of a partial reduction of TiIV to TiIII. The color intensity increased with increasing TiO2 content and irradiation time.
