“…Chitosan coatings have been obtained by cathodic electrophoretic deposition in previous research [8,9]. Bioactive glasses have excellent bioactivity and biocompatibility, they are used in several biomedical applications, for example non-load-bearing implants, bone cements, tissue engineering scaffolds, drug delivery systems, and bioactive coatings [10][11][12][13][14].…”

“…And the pitting corrosion potential of modified SS is about 1.1 V, which is supposed to be higher than the expected one under prevailing redox conditions in most applications in the human body [26] . Therefore, the β-CD coating can act as a protective layer to improve the corrosion performance.…”

“…It is well known that a higher Z modulus at low frequency displays a better corrosion resistance. In the same frequency range, the modified SS exhibits a relative higher Z modulus and a broader phase angle, suggesting a higher corrosion resistance than the virgin SS [26] . And known from Nyquist [ Fig.6(B)] plots and Table 1, the charge-transfer resistance of electrodeposited SS is 1.019×10 6 Ω/cm 2 , better than that of virgin SS(9.096×10 5 Ω/cm 2 ).…”

β-Cyclodextrin(β-CD) can be used for drug loading and release in biomedical application. β-Cyclodextrinsalicylate(β-CD-S) was synthesized by transesterification and then was electrodeposited on the surface of stainless steel(SS) by the anodic electrooxidation polymerization of the salicylate. 1 H NMR spectrometry was used to determine the structure of β-CD-S. FTIR spectroscopy and XPS were applied to verifying the synthesized β-CD-S and the existence of the electrodeposited layer on the SS surface, respectively. Tafel plots and electrochemical impedance spectroscopy(EIS) technologies were used to estimate the corrosion resistance of β-CD-covered stainless steel. Electrochemical quartz crystal microbalance was applied to determining the drug loading of the stainless steel before and after its modification. E. coli was selected as a harmful microbe to evaluate the antibacterial properties of the stainless steel with the comparison of optical density values.

“…The thickness, morphology and hydrophobicity of the coatings can be significantly controlled by the applied electric field alone during ePD. Numerous papers have been published concerning the electrophoretic deposition of chitosan coatings on stainless steel substrates [13,28,29]. Most of the papers present investigation of the kinetics of ePD of chitosan from aqueous dilute suspensions [13] and investigation of corrosion resistance of the coated steel [28].…”

In this study, chitosan coatings were electrophoretically deposited (EPD) on near-β Ti-13Nb-13Zr alloy. The influence of colloidal solution composition and EPD parameters on the quality of chitosan coatings was investigated. It was established that the uniformity of as-deposited chitosan coatings is highly dependent on the chemical composition of the solution used for EPD, the pH, electrophoretic mobility and zeta potential of chitosan colloidal molecules, as well as EPD parameters, such as potential difference value and deposition time. The microstructure of the coatings was investigated using electron microscopy and X-ray diffractometry. The coatings 350 nm thick were homogeneous and exhibited an amorphous structure. The coatings had low hardness and Young’s modulus. The effect of surface of the substrate preparation prior to coating deposition on the adhesion of chitosan coatings to the Ti-13Nb-13Zr alloy was also investigated. The coatings exhibited good adhesion to the non-acid-etched surface of the titanium alloy.
