Surface Modification by Plasma Polymerization and Application of Plasma Polymers as Biomaterials
The work described in this thesis concerns the plasma polymers used for immobilization and adsorption of biomolecules. In particular, thin polymeric films bearing ether, anhydride, and amine functionalities were synthesis by plasma polymerization of these group containing monomers, i.e. di-(ethylene glycol) vinyl ether (EO2), maleic anhydride (MA), and allylamine (AA). Additionally, the charact...
متن کاملSurface Modification of Titanium by Plasma Nitriding
A systematic investigation was undertaken on commercially pure titanium submitted to plasma nitriding. Thirteen different sets of operational parameters (nitriding time, sample temperature and plasma atmosphere) were used. Surface analyses were performed using X-ray diffraction, nuclear reaction and scanning electron microscopy. Wear tests were done with stainless steel Gracey scaler, sonic app...
متن کاملPoly(dimethyl siloxane) surface modification by low pressure plasma to improve its characteristics towards biomedical applications.
Poly(dimethyl siloxane) elastomer, (PDMS) is widely used as a biomaterial. However, PDMS is very hydrophobic and easily colonized by several bacteria and yeasts. Consequently, surface modification has been used to improve its wettability and reduce bacterial adhesion. The aim of this work was to modify the PDMS surface in order to improve its hydrophilicity and bacterial cell repulsion to be us...
متن کاملCatalytic and Non-catalytic Conversion of Methane to C2 Hydrocarbons in a Low Temperature Plasma
The direct conversion of methane to C2 hydrocarbons, in a quartz tube reactor enforced by a DC corona discharge, was investigated at atmospheric pressure. The process was carried out in the presence of metal oxide catalysts of Mn/W/SiO2, Mn/W/SiO2 (tetraethyl orthosilicate, TEOS), and Mn/W/CNT (supported on carbon nanotubes). The total yield to C2 hydrocarbons in the presence of metal oxide cat...
متن کاملLow Temperature Plasma CVD Grown Graphene by Microwave Surface-Wave Plasma CVD Using Camphor Precursor
Hydrocarbon precursor such as methane has been widely used to grow graphene films and the methods of growing quality graphene films are dominated by thermal CVD (chemical vapor deposition) system. Graphene films grown by plasma process are generally highly defective which in turns degrade the quality of the films. Here, using a green precursor, camphor we demonstrate a simple and economical met...
