“…Chitosan possess good biocompatibility, chemical resistance, mechanical strength, antimicrobial properties and thermal stability and have been utilized successfully in biotechnology, for different applications. The hydroxyl apatite chitosan nanocomposite was obtained on stainless steel to provide better corrosion protection [14,15]. Chitosan is widely used in industry due to its film forming and gelation characteristics.…”

A Zinc-Chitosan composite coating was generated on mild steel from zinc sulphate-sodium chloride electrolyte by electrodeposition. The electrolyte constituents were optimized for good composite coating. The corrosion resistance behavior of the composite was examined by weight loss, polarization and impedance methods using 3.5 wt% NaCl neutral solution as medium. Separate polarization profiles were recorded for composite coating and compared with zinc coated sample. SEM images of coatings were recorded for the pure and composite coating.

“…Later on several other studies dealing with the anticorrosive effect of starch [202][203][204], pectin [205][206][207][208][209][210], dextrin & cyclodextrin [13,[211][212][213][214][215], pectate [216,217], algenates [218,219] and exudate gums [220][221][222][223][224][225] are reported for metals and alloys in different electrolytes. Synergistic effect of halide ions is also reported for different classes of biopolymers [226][227][228][229]. Similar to chitosan, cellulose and their derivatives, these polymeric carbohydrates also behave as mixed-type corrosion inhibitors.…”

However, some polymers show low solubility in aqueous solutions and undergo decomposition at higher temperatures (Solomon et al 2017).…”

Phenolic acid grafted chitosan has widespread drug delivery applications, as bio adsorbent, packing material, etc., due to its excellent antioxidant and antimicrobial properties. However, for the first time, the anticorrosive efficiency of ferulic acid modified chitosan has been investigated. The prepared chitosan derivative is characterized using spectral methods, thermal analytical methods, surface charge, and particle size analysis. The evaluation of corrosion inhibition potential showed a highest value of 95.96 % at 303 K. Thermodynamic activation and adsorption parameters endorse a mixed adsorption process involving an initial electrostatic interaction followed by chemisorption. Electrochemical studies gave results which agreed well with the gravimetric studies. Surface morphological studies were performed using contact angle measurements, FESEM, EDAX, AFM, optical profilometric and UV spectral techniques. Computational studies involving quantum chemical calculations, Monte Carlo and molecular dynamic simulation studies, and radial distribution function analysis are further done to validate the experimental results.
