摘要

Combination of a natural biodegradable polymer with a synthetic polymer delivers admirable capability in advanced biomedical materials. For this purpose, biodegradable conductive composites based on polypyrrole/Pectin will be synthesized by in situ electrochemical polymerization of pyrrole in the presence of Pectin in oxalic acid medium Raman and UV-Vis spectroscopy will be used to characterize the synthesized bio-composites. Raman spectrum will be employed to find the interaction between the π-conjugated structure of PPy and the Pectin units in the investigated composite. SEM results reveal the influence of the Pectin inclusion on polypyrrole surface morphology. Electrochemical corrosion behavior of the coated implant alloys in simulated body fluid (SBF) medium will be examined using potentiodynamic polarization and electrochemical impedance spectroscopic measurements. Further, in vitro cell culture studies will also be carried out using MG-63 human osteoblast cells to estimate the biocompatibility of PPy/Pectin composite coatings. Significant enhancements in surface protective and biocompatibility performance will be expected and it will suggest possible application as a bioactive coating material on 316L SS implants for biomedical fields.
