characterization and protein adsorption behavior of deposited organic thin film onto titanium by Plasma Polymerization with hexamethyldisiloxane
Biomaterials, 2004Co-Authors: Tohru Hayakawa, Masao Yoshinari, Kimiya NemotoAbstract:Abstract Plasma polymerized hexamethyldisiloxane (HMDSO) thin film was deposited onto titanium using a radio-frequency apparatus for the surface modification of titanium. A titanium disk was first polished using colloidal silica at pH=9.8. Plasma-polymerized HMDSO films were firmly attached to the titanium by heating the titanium to a temperature of approximately 250°C. The thickness of the deposited film was 0.07–0.35 μm after 10–60 min of Plasma Polymerization. The contact angle with respect to double distilled water significantly increased after HMDSO coating. X-ray photoelectron spectroscopy revealed that the deposited thin film consisted of Si, C, and O atoms. No Ti peaks were observed on the deposited surface. The deposited HMDSO film was stable during 2-weeks immersion in phosphate buffer saline solution. Fourier transform reflection–absorption spectroscopy showed the formation of Si–H, Si–C, C–H, and CO bonds in addition to Si–O–Si bonds. Quartz crystal microbalance-dissipation measurement demonstrated that the deposition of HMDSO thin films on titanium has a benefit for fibronectin adsorption at the early stage. In conclusion, Plasma Polymerization is a promising technique for the surface modification of titanium. HMDSO-coated titanium has potential application as a dental implant material.

recent advances in polymer thin films prepared by Plasma Polymerization synthesis structural characterization properties and applications
Surface & Coatings Technology, 1996Co-Authors: Frank F ShiAbstract:Abstract In this paper, the basic features of Plasma Polymerization of organic thin films are reviewed. Principal synthesis technologies generally used precursors and new developments in the 1990s are taken into account. Effects of Plasma Polymerization conditions on the structures and properties of the films are briefly discussed. Modern analytical techniques used for characterization of Plasma polymer firms, such as Fourier transform infrared and electron spectroscopy for chemical analysis, etc., are systematically reviewed. Physical properties, including surface properties, permeability, electrical and optical properties, are concisely described with the emphasis on the studies in recent literature. Some proposed applications of these films in mechanical, electrical and optical industry are presented.

macroscopic control of dmahema and hema Plasma Polymerization to tune the surface mechanical properties of hydrogel like coatings
Plasma Processes and Polymers, 2017Co-Authors: Matthieu Veuillet, Lydie Ploux, Aissam Airoudj, Yannick Gourbeyre, Emmanuelle Gaudichetmaurin, Vincent RoucoulesAbstract:Macroscopic kinetics of DMAEMA and HEMA Plasma Polymerization have been investigated. Different regimes in the kinetics of growth have been identified and the resulting Plasma polymer surfaces have been characterized by Infrared and X-ray photoelectron spectroscopies as well as by wettability analysis. Various hydrogel properties have been obtained leading to different surface mechanical properties. The values of Young's modulus estimated by AFM nanoindentation were found to be systematically high in the case of DMAEMA Plasma Polymerization (4–6 MPa). However, in the case of HEMA Plasma Polymerization, the Young's modulus values could be tune to 1 MPa up to 4.5 MPa. This result was even more remarkable as chemical composition of the corresponding surfaces was quasi-identical.

a chemometric investigation of the effect of the process parameters during maleic anhydride pulsed Plasma Polymerization
Analytica Chimica Acta, 2005Co-Authors: Frederic Siffer, Arnaud Ponche, Philippe Fioux, J Schultz, Vincent RoucoulesAbstract:Plasma Polymerization is a good candidate to functionalise solid surfaces. In particular, pulsed Plasma Polymerization produces polymer thin films with good structural retention of the monomer. The present work consists in a systematic investigation of the influence of parameters during maleic anhydride pulsed Plasma Polymerization. The following parameters have been considered in the present study: on-time Polymerization, off-time Polymerization and peak power. After preliminary experiments based on a factorial design, a central composite design was applied to optimise the three factors. Predicted and experimental response as anhydride groups retention, thickness and roughness of Plasma polymer thin films were compared. The film chemical structures were obtained using X-ray photoelectron spectroscopy (XPS), the film thickness by ellypsometry measurements and the film roughness by AFM analysis.
