The potential of nano-structured silicon oxide type coatings deposited by PACVD for control of aquatic biofoulingAkesso, Laurent ...SiO[sub]x-like coatings were deposited on glass slides from a hexamethylsiloxane precursor by plasma-assisted CVD (PACVD). Surface energies (23.1-45.7 mJ m[sup]{-1}) were correlated with the degree ... of surface oxidation and hydrocarbon contents. Tapping mode AFM revealed a range of surface topologies with Ra values 1.55-3.16 nm and RMS roughness 1.96-4.11 nm. Settlement of spores of the green alga Ulva was significantly less, and detachment under shear significantly more on the lowest surface energy coatings. Removal of young plants (sporelings) of Ulva under shear was positively correlated with reducing the surface energy of the coatings. The most hydrophobic coatings also showed good performance against a freshwater bacterium, Pseudomonas fluorescens, significantly reducing initial attachment and biofilm formation, and reducing the adhesion strength of attached bacterial cells under shear. Taken together the results indicate potential for further investigation of these coatings for applications such as heat exchangers and optical instruments.Source: Biofouling. - ISSN 0892-7014 (Vol. 25, iss. 1, 2009, str. 55-67)Type of material - article, component part ; adult, seriousPublish date - 2009Language - englishCOBISS.SI-ID - 707754
