“…Similar results were observed during the ultraviolet-visible (UV-Vis) spectroscopy studies, where the CS-TiO 2 exhibited a strong absorption band at 300-500 nm (with CS, no absorbance occurred at 350-800 nm) promoted by the incorporation of TiO 2 in the composite through hydrogen bonding [42]. Furthermore, the CS-Ag-TiO 2 and CS-halloysite-TiO 2 composites showed good stability (zeta potential 31-39 mV) during storage [43,44]. The CS-TiO 2 composite showed a type II isotherm indicating that the material is macroporous in nature [45].…”

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]...

The introduction of two new benzimidazole derivatives, 2-nonyl-1H-benzo [d] imidazole (NB) and 2-benzyl-1-hexyl-1H-benzo [d]imidazole (HB), as corrosion inhibitors for steel is presented, and their activities are compared with 1Hbenzo[d]imidazole (B). The experimental performance of these molecules was evaluated by electrochemical techniques, surface observations, and contact angle measurement. The results showed the prominent action with inhibition efficiencies of 98.8% and 99.3% for 3 mM of NB and HB, respectively, at 303K. They are adsorbed on the metal surface base on Langmuir isotherm. It is noteworthy to note that increment of environment acidity causes more efficiency for both molecules so that the order of inhibitive activity in different pHs is pH = 2>pH = 1>pH = 0.1. Additionally, HB provides little better protection than NB. Statistical analysis was conducted to identify influential factors on the efficiency of HB and NB. A general factorial model in the main effect order was used by design of experiment 7 software. Analysis of variance resulted in acceptable R 2 values of 99% and 98% and significance of the applied model. Quantum chemical calculations were carried out to find the optimum structure, molecular parameters, and local reactive sites in gas and solution phase. Calculations exhibited a planar structure for 1-hexyl-1H-benzo[d]imidazole and 2-nonyl-1H-benzo [d]imidazole that is the reason of their high efficiencies.
