“…Coatings deposited from each of the monomers showed retention of all major spectral bands after plasma polymerisation. Spectral bands present in coatings deposited from each of the monomers were identified in the copolymer spectrum also and were found to be in agreement with those reported previously concerning plasma polymerisation of both the TMCTS monomer [37] and the PFOTES monomers [38].…”

Protein adsorption is one of the key parameters influencing the biocompatibility of medical device materials. This study investigates serum protein adsorption and bacterial attachment on polymer coatings deposited using an atmospheric pressure plasma jet system. The adsorption of bovine serum albumin and bovine fibrinogen (Fg) onto siloxane and fluorinated siloxane elastomeric coatings that exhibit water contact angles (θ) ranging from superhydrophilic (θ < 5°) to superhydrophobic (θ > 150°) were investigated. Protein interactions were evaluated in situ under dynamic flow conditions by spectroscopic ellipsometry. Superhydrophilic coatings showed lower levels of protein adsorption when compared with hydrophobic siloxane coatings, where preferential adsorption was shown to occur. Reduced levels of protein adsorption were also observed on fluorinated siloxane copolymer coatings exhibiting hydrophobic wetting behaviour. The lower levels of protein adsorption observed on these surfaces indicated that the presence of fluorocarbon groups have the effect of reducing surface affinity for protein attachment. Analysis of superhydrophobic siloxane and fluorosiloxane surfaces showed minimal indication of protein adsorption. This was confirmed by bacterial attachment studies using a Staphylococcus aureus strain known to bind specifically to Fg, which showed almost no attachment to the superhydrophobic coating after protein adsorption experiments. These results showed the superhydrophobic surfaces to exhibit antimicrobial properties and significantly reduce protein adsorption.

“…Disp(G) was calculated as a slope of the G peak position vs excitation wavelength. The bond strengths written in brackets suggest the tendency to break N-H and Si-N bonds easily but with more difficulty in breaking Si-C and C-H bonds [31]. Chemical composition of the films measured by XPS technique is given in Table 1.…”

“…Because of a large difference between the main gas and the argon carrier gas flow rate, a vortex was formed inside the plasma-discharging area. The vortex caused radicals to stay in the air for a long time, and this resulted in the formation of particles on the substrates [9]. As the argon carrier gas flow rate increased, the rough surface of the SiO x buffer layers caused low surface kinetics of the sputtered atoms and a decrease in the nuclei density [10].…”
