Metallic materials are the most used materials as orthopedic or dental implants due to their excellent mechanical *** they are not able to create a natural bonding with the mineralized bone and occasionally suffer localized *** work describes the electrochemical behavior of a hybrid sol-gel thin film with the addition of green *** films enhance the ability of the implant to make a union with the existing bone and improve its resistance to aggressive *** ethanol solution of the polymerized vinyltrimethoxysilane(PVTMS) was mixed with an aqueous solution of henna extract(Lawsonia inermis) and refluxed to give homogeneous *** hybrid PVTMS/henna thin films were deposited on the stainless steel 316L by *** morphology,composition and adhesion of hybrid sol-gel coatings have been examined by SEM,EDX and pull-off test,*** of high additive concentrations(0.1%) did not disorganize the sol-gel *** pull-off test recorded a mean coating-substrate bonding strength larger than 20.6 MPa for the hybrid sol-gel *** effect of henna extract,with various added concentrations from 0.012% to 0.1%,on the anticorrosion properties of sol-gel films have been characterized by electrochemical impedance spectroscopy(EIS) and potentiodynamic polarization tests in simulated body fluid(SBF) solution and has been compared to the bare *** extract additions(0.05%) have significantly increased the corrosion protection of the sol-gel thin film to higher than 90%.The in vitro bioactivity of prepared films indicates that hydroxyapatite nuclei can form and grow on the surface of the doped sol-gel thin *** present study shows that due to their excellent anticorrosion properties,bioactivity and bonding strength to substrate,doped sol-gel thin films are practical hybrid films in biomedical applications.
