“…The improvement of UV resistance using anatase TiO 2 was demonstrated in [17] when microand nanoparticles were impregnated on acacia hybrid wood. The exposure of the treated wood at UV radiation 960 h did not lead to color changes.…”

“…An inefficient polymer coating can lead to loss in mechanical properties and integrity of the matrix and wood discoloration due to lignin degradation. New composite materials were developed, as aromatic impregnating agents (insecticides or fungicides) such as creosote, halogenated carbamates, benzothiazoles, pentachlorophenol, (alkyl) imidazoles, bis (tributyltin) oxide, or salt-based impregnates such as borates, quinolinolates, naphthenates of copper, zinc or chromated copper arsenate-based preservatives (CCA) in several commercial variants and so forth [8][9][10], fluoroalkyl functional oligomeric silane system [11], short-chain amino silicones [12], alkoxysilanes with different organic groups [R'Si(OR″)] [13], zinc oxide (ZnO) nanoparticles dispersed in maleic anhydride-modified polypropylene (MAPP) [14], and titanium dioxide (TiO 2 ) nanoparticles [15][16][17][18][19].…”

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.

“…In addition, TiO 2 can provide to wood different degrees of wettability, enabling its application in different conditions (Gao et al 2015). It also protects wood against UV degradation (Tuong and Chu 2015). Wang et al (2012) observed that TiO 2 gels can increase the stiffness of the wood cell wall and then improves the wood mechanical strength.…”

“…Heat treatment is a wood modification method successfully used for solid wood both at experimental and commercial levels. Previous studies on solid wood showed that heat treatment could reduce wood hygroscopicity, improve dimensional stability, and biological resistance without contaminating the environment . Marcos and Hale studied the effect of chemical changes on the wood‐moisture relationships in thermally modified wood and found that most wood‐moisture properties were strongly correlated with changes in chemical constituent in thermally modified wood.…”

Properties of glycerin-thermally modified wood flour/polypropylene composites

This study aimed to investigate the combination effect of glycerin treatment and thermal modification of wood flour on the physical, mechanical, thermal dynamic mechanical properties of wood flour/polypropylene (PP) composite. The morphological aspect was also investigated. The wood flour was first impregnated in the aqueous solution of glycerin, followed by heat treatment at 200°C for 1 h. Then the unmodified or modified wood flour was blended with PP at a weight ratio of 4:6 to prepare composites. Moisture adsorption experiment and X‐ray photoelectron spectroscopy analysis of wood flour demonstrated that the hygroscopicity and the free surface hydroxyl groups of wood flour decreased after glycerin‐thermal modification. Thickness swelling of the 10% wt glycerin‐thermally modified wood flour/PP composite was reduced by 42.8% after 96 h immersion as compared to unmodified control. Evaluation of mechanical properties in impact and flexure modes indicated that glycerin treatment alone had no significant effect, but the combination of glycerin and thermal treatment slightly decreased the strength, with the exception of 10% glycerin and heat modified sample. Dynamic mechanical analysis and scanning electron microscope illustrated the improved interfacial bonding between PP and wood flour modified by 10% glycerin and heat treatment. POLYM.
