“…Similar trends were observed in the OVP properties through the incorporation of nano-TiO 2 to CS films according to Peng et al [59] and Lian et al [60], who stated that the presence of TiO 2 significantly improves the film functionality by reducing the exchange of oxygen through the CS-TiO 2 composite film [66]. Besides, no significant differences in water solubility were observed between CS and CS-TiO 2 films [57]. The presence of TiO 2 reduces the swelling degree of CS-TiO 2 in a dose-dependent response [49,63].…”

“…The functionalization of the CS matrix through the incorporation of TiO 2 has gained attention since it can impart the CS-TiO 2 composite with an enhancement of its mechanical properties [27] because it can act as a reinforcing agent [26], with a slightly increased film thickness (70 µm) compared with CS (66 µm) [57]. Amin and Panhius [23] reported that TiO 2 (30% vs. 70% CS) significantly improves the mechanical properties (an increase of Young's modulus in 11.8-fold, a six-fold increase for both tensile strength and toughness) of the CS film.…”

“…Water vapor permeability (WVP) and oxygen vapor permeability (OVP), as well as water solubility, swelling capacity, and biodegradability rates, are the most important properties that should be considered during the development of packaging and/or wound-healing materials for food and biomedical applications [40,57,59,60]. In general, water and oxygen permeability values of CS films depend on various interrelated factors such as the structural characteristics of the polymeric chains, hydrogen bonding features and other intermolecular interactions, degree of cross-linking, and dispersion of nanoparticles into the polymeric matrix [1].…”

“…Similar results were reported on ethylene photo-degradation (in vitro and TiO 2 dose-dependent) by Siripatrawan and Kaewklin [40] and Zhang et al [54] using a CS-TiO 2 nanocomposite and CS-TiO 2 -black plum peel extract (BPPE) films, respectively. The authors suggested that the incorporation of BPPE into CS-TiO 2 composite improves the antioxidant capacity of the resulting packaging material [57].…”

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]...
