“…The aluminum corrosion resistance may be attributable to the formation of a dense network structure formed by the Al¬-O-Ti-O-Si-O-Si bond. Meanwhile, Ledwing et al [110] achieved the optimization of electrophoretic deposition parameters for manufacturing of TiO 2 /CS composite coating on X2CrNiMo17-12-2 stainless steel. This hybrid coating (4-8 µm thickness film) improved the corrosion resistance of steel (−165 to −110 Ecorr) compared to uncoated steel (−291 Ecorr), and the composite coating exhibited a fully uniform distribution of TiO 2 (3 g L −1 ) nanoparticles on the chitosan (0.5 g L −1 ) surface.…”

In recent years, a strong interest has emerged in hybrid composites and their potential uses, especially in chitosan-titanium dioxide (CS-TiO 2 ) composites, which have interesting technological properties and applications. This review describes the reported advantages and limitations of the functionalization of chitosan by adding TiO 2 nanoparticles. Their effects on structural, textural, thermal, optical, mechanical, and vapor barrier properties and their biodegradability are also discussed. Evidence shows that the incorporation of TiO 2 onto the CS matrix improves all the above properties in a dose-dependent manner. Nonetheless, the CS-TiO 2 composite exhibits great potential applications including antimicrobial activity against bacteria and fungi; UV-barrier properties when it is used for packaging and textile purposes; environmental applications for removal of heavy metal ions and degradation of diverse water pollutants; biomedical applications as a wound-healing material, drug delivery system, or by the development of biosensors. Furthermore, no cytotoxic effects of CS-TiO 2 have been reported on different cell lines, which supports their use for food and biomedical applications. Moreover, CS-TiO 2 has also been used as an anti-corrosive material. However, the development of suitable protocols for CS-TiO 2 composite preparation is mandatory for industrial-scale implementation.Materials 2020, 13, 811 2 of 27 they are synthesized by different methods (intercalation of the polymer, sol-gel, hydrothermal, electro-deposition, chemical and physical vapor deposition, suspension and liquid phase deposition). These methods are effective to enhance the technological and mechanical properties of each individual component and also reveal new functionalities [1,3]. Currently, there is a special interest in combining natural polymers such as chitosan (CS) with inorganic materials like titanium dioxide (TiO 2 ) to obtain hybrid composites (CS-TiO 2 ) with beneficial properties [3][4][5][6].Chitosan (CS) is a natural biopolymer (linear polysaccharide comprising 1-4 linked 2-amino-deoxy-β-D-glucan) generally obtained by deacetylation of chitin, the main structural component of crustacean exoskeletons. CS exhibits a poly-cationic character and is non-toxic and biodegradable [7]. CS is considered a biological functional compound with multiple interesting properties. It can form films for food and pharmaceutical applications, including edible coatings, packaging material, or as drug-eluting carrier [5,7]. Its adsorbent capacity can have environmental applications during photocatalytic processes of waste-water treatment [8], and it also has inherent antibacterial and antifungal properties [9]. It is biocompatible with several organic and inorganic compounds by the presence of free amino and hydroxyl functional groups in its structure, which can react with other functional groups by electrostatic forces, hydrogen bonds, or by compound-soak up into the polymeric matrix, thus improving its mechanical and biological properties [10]...

In this study, nc-TiO 2 /Ni-Fe composite coatings, and Ni-Fe alloys as equivalents to their matrices, were obtained from citratesulphate baths in the electrodeposition process using direct current and pulse current conditions. The aim of the study was to examine the effects of TiO 2 nanoparticles and current conditions on the chemical composition, surface morphology, microstructure, microhardness and magnetic properties of the electrodeposited coatings. The results show that the concentration of Fe in Ni-Fe alloys is related to the current conditions and is higher in the case of pulse current electrodeposition, while such a relationship was not observed for composites. The reinforcement of composites with TiO 2 nanoparticles results in a more developed surface topography with many nodule-like structures. Composites and equivalent alloys deposited in pulse current are characterized by a finer grain size than those obtained in direct current. TiO 2 nanoparticles and their agglomerates, several tens of nanometres in size, are distributed randomly in the Ni-Fe matrix of composites deposited in both current conditions used. Incorporation of a high volume fraction of nc-TiO 2 , exceeding over a dozen percent, and decreasing the nanograin size in nc-TiO 2 /Ni-Fe composites electrodeposited under pulse current conditions, allow a higher hardness to be achieved than in their counterparts obtained using direct current. Magnetic measurements showed ferromagnetic ordering of pristine TiO 2 nanoparticles, however, the introduction of TiO 2 nanoparticles into the Ni-Fe matrix resulted in a decrease in coercivity and saturation magnetization.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

“…The thickness of the layer could be adjusted by controlling the deposition parameters like deposition time, applied current/voltage, solvent type and suspension loading (Narayan and Raturi 2012 ). Researchers have employed various combinations of titanium dioxide thin film deposits for real-time applications like dye-sensitized solar cells (Xue et al 2012 ), biomedical applications (Narkevica et al 2017 ) and ceramic coatings (Ledwig et al 2017 ). Nyongesa and Aduda ( 2017 ) employed electrophoretic deposition to deposit thin films of titanium dioxide onto glass substrates for application in water treatment.…”

Global pollution is calling for advanced methods to remove contaminants from water and wastewater, such as TiO 2 -assisted photocatalysis. The environmental applications of titanium dioxide have started after the initial TiO 2 application for water splitting by Fujishima and Honda in 1972. TiO 2 is now used for self-cleaning surfaces, air and water purification systems, microbial inactivation and selective organic conversion. The synthesis of titanium dioxide nanomaterials with high photocatalytic activity is actually a major challenge. Here we review titanium dioxide photocatalysis with focus on mechanims, synthesis, and applications. Synthetic methods include sol-gel, sonochemical, microwave, oxidation, deposition, hydro/solvothermal, and biological techniques. Applications comprise the production of energy, petroleum recovery, and the removal of microplastics, pharmaceuticals, metals, dyes, pesticides, and of viruses such as the severe acute respiratory syndrome coronavirus 2.
