“…TiO 2 nanoparticles can impart hydrophobic or hydrophilic properties to the material, fungicidal, and bactericidal protection and present photo-catalytic activity. Using TiO 2 as coating for wood items ensures anisotropy, wettability, and UV protection [46,[68][69][70][71].…”

The complex methods of diagnosis investigation of the wood artifacts state and proper materials for their protection against decay are very important goals in cultural heritage. This chapter focuses on the recent trends in micro-and nanostructured polymer systems for application in cultural heritage and on wood preservation, especially. The synthesis, properties, and applications, as well as the relevant analysis techniques to reveal the structures and properties of polymer systems, are discussed, too. To overcome the specific problems that exist for wood artifacts, some aspects should be treated: effects of the environmental factors, as moisture and pollutant absorption into the wood fibers, over-exposure effect of sun or artificial light sources, biological attack of different microorganisms, and the effects of the protective and decorative coatings.

“…TiO 2 , as a white pigment, is widely used in various applications in our daily life such as paints, coatings and plastics due to its outstanding covering power and UV absorption performance. In recent years, TiO 2 pigment has gradually replaced other materials owing to the higher light scattering and lower cost than other metal oxides, while also being transparent and colorless [8,9]. TiO 2 is, however, a semiconductor oxide, thus showing photocatalytic activity upon UV radiation absorption, which causes severe damage to most polymers via a photochemical reaction [10][11][12].…”

Dimethyl toluene-2,4-dicarbamate (2,4-TDC) was selected as a model compound for aromatic polyurethane to investigate the photo-chemical behavior of commercial TiO 2 pigments in non-aqueous solution. The UV-Visible spectrometry analysis results showed that the UV-shielding ability of the rutile TiO 2 pigment was better than that of the anatase TiO 2 pigment. Photodegradation experiments suggested that the photodegradation of 2,4-TDC was retarded by rutile TiO 2 pigment, while accelerated by anatase TiO 2 pigment. With the help of the degradation intermediates during the photodegradation process and calculated data, such as point charges and bond length, the preliminary photodegradation mechanism of 2,4-TDC was also briefly elucidated, including the addition of hydroxyl radicals and the cleavage of the carbamate side chain. Additionally, the photodegradation of 2,4-TDC was used to evaluate the photoreactivity of TiO 2 pigments, this is proved to an efficient approach with potential application in industry.

“…[35] Veronovski et al synthesized TiO 2 -SiO 2 composite coatings on wood surfaces, which offered long-term protection to UV-sensitive wood substrates. [36] Furthermore, we used wood as a substrate to prepare a material with photocontrolled wettability. It is supposed that a wood surface with light-reversible wettability based on an anatase-TiO 2 film is of significance for improving the performance of wood products and is desirable where self-cleaning or manipulation in response to indoor or outdoor humidity is required.…”

Journal of Wood Chemistry and TechnologyPublication details, including instructions for authors and subscription information:The reversible photocontrol of wood-surface wettability between superhydrophilicity and superhydrophobicity based on a TiO 2 film modified with octadecyl trichlorosilane (OTS) was achieved via a facile hydrothermal method at low temperature. Under UV illumination, the wood surface became superhydrophilic with a water contact angle (WCA) of approximately 0 • . However, when placed in the dark, a superhydrophobic wood surface with a WCA of approximately 152 • was achieved. The mechanism of the reversible photocontrol of woodsurface wettability is discussed in this article. This photocontrolled wood surface may have potential for wood self-cleaning or manipulation in response to indoor humidity.
