Abstract: Recently, the development of hybrid composites has witnessed remarkable growth because they exhibit many applications, including environmental and medical applications [ 1 , 2 ]. Organic–organic (e.g., chitosan (CS)–starch, CS-protein, and CS-alginate), organic–inorganic (e.g., starch–TiO 2 , alginate–TiO 2 , and chitosan–TiO 2 ), and inorganic–inorganic (e.g., titanium dioxide (TiO 2 )–Ag, TiO 2 –MgO, and TiO 2 –ZnO) complexes can be combined to create hybrid composites. These techniques work well to disclose new functionality and improve the mechanical and technological qualities of each individual component [ 1 , 3 ]. Combining inorganic materials like TiO 2 with natural polymers like CS to make hybrid composites (CS–TiO 2 ) with advantageous characteristics is currently of particular interest [ 3 , 4 , 5 , 6 ]. Because CS biopolymer, which is derived from chitin, has several advantageous qualities, including non-toxicity, biocompatibility, and biodegradability, research on it has become crucial to the creation of nanocomposites (NCs) [ 7 ]. CS has different functional groups, such as amine and hydroxyl groups, which allow it to interact with nanoparticles in a way that stabilizes NCs and improves their operating efficiency [ 8 , 9 ]. CS-based NCs become robust materials with antibacterial activity, antioxidant capacity, and wound-healing capability, leading to become ideal and suitable for biomedical applications, food packaging, and environmental requirements [ 10 ]. Their antibacterial and pollutant-binding properties are responsible for their effectiveness in water filtration. Due to the nature of biopolymers in stabilizing or strengthening materials, or performing a dual function, in conjunction with polymers, carbonaceous materials, and metal oxides, a variety of industries use CS to produce NCs [ 11 ]. Research on bio-functional materials and green nanotechnology relies heavily on CS owing to its structure–function link [ 12 , 13 ].
