“…By increasing the content of the PSO, the stress of the coating decreased at the same strain. This result was in agreement with the results of Truby's [25]. In order to analyze the reason causing the decrease of the mechanical properties of the coating, crosslink density of the coating was measured.…”

“…Although the potential of silicone oil to affect the ability to overcome cellular barriers has been pointed out [17], there is no statistical evidence to support these concerns [13,20]. The incorporation of silicone oil into fouling release coatings based on PDMS showed that the amount of silicone oil was negligible [22,23], and the low toxicity of silicone oil caused little harm in marine life [24][25][26].…”

Abstract:In this study, phenylmethylsilicone oil (PSO) with different viscosity was used for research in fouling release coatings based on polydimethylsiloxane (PDMS). The surface properties and mechanical properties of the coatings were investigated, while the leaching behavior of PSO from the coatings was studied. Subsequently, the antifouling performance of the coatings was investigated by the benthic diatom adhesion test. The results showed that the coatings with high-viscosity PSO exhibited high levels of hydrophobicity and PSO leaching, while the high PSO content significantly decreased the elastic modulus of the coatings and prolonged the release time of PSO. The antifouling results indicated that the incorporation of PSO into coatings enhanced the antifouling performance of the coating by improving the coating hydrophobicity and decreasing the coating elastic modulus, while the leaching of PSO from the coatings improved the fouling removal rate of the coating. This suggests a double enhancement effect on the antifouling performance of fouling release coatings based on PDMS with PSO incorporated.

Factors that influence elastomeric coating performance: the effect of coating thickness on basal plate morphology, growth and critical removal stress of the barnacleBalanus amphitrite

et al. 2006

Silicone coatings are currently the most effective non-toxic fouling release surfaces. Understanding the mechanisms that contribute to the performance of silicone coatings is necessary to further improve their design. The objective of this study was to examine the effect of coating thickness on basal plate morphology, growth, and critical removal stress of the barnacle Balanus amphitrite. Barnacles were grown on silicone coatings of three thicknesses (0.2, 0.5 and 2 mm). Atypical (''cupped'') basal plate morphology was observed on all surfaces, although there was no relationship between coating thickness and i) the proportion of individuals with the atypical morphology, or ii) the growth rate of individuals. Critical removal stress was inversely proportional to coating thickness. Furthermore, individuals with atypical basal plate morphology had a significantly lower critical removal stress than individuals with the typical (''flat'') morphology. The data demonstrate that coating thickness is a fundamental factor governing removal of barnacles from silicone coatings.

“…Truby et al (2000) showed that oil incorporation may prove beneficial in decreasing the adhesion of barnacles and certain species of oysters. Bacterial settlement patterns on silicone coatings amended with oils of various compositions were dependent upon the hydrophilicity of the oil that was incorporated into a silicone matrix (Dalton et al, 2000).…”

“…The use of tin will be banned in 2008, and copper usage is regulated in some European countries (Walker, 1998). Silicone foul-release coatings are currently under evaluation as an alternative nontoxic technology (Callow & Fletcher, 1994;Brady, 2000;Darkangelo Wood et al, 2000;Truby et al, 2000). Although organisms can attach to silicones, they can be removed either by brushing or by hydrodynamic self-cleaning (Callow et al, 1988;Meyer et al, 1994;Swain & Schultz, 1996).…”

Structure-Property Relationships of Silicone Biofouling-Release Coatings: Effect of Silicone Network Architecture on Pseudobarnacle Attachment Strengths

Model silicone foul-release coatings with controlled molecular architecture were evaluated to determine the effect of compositional variables such as filler loading and crosslink density on pseudobarnacle attachment strength. Pseudobarnacle adhesion values correlated with filler loadings in both condensation and hydrosilylation-cured silicones. Variation of crosslink density of hydrosilylationcured silicones had an insignificant effect on attachment strength. X-ray photoelectron spectroscopy (XPS) indicated that the mode of failure upon detachment of the pseudobarnacle was dependent upon the crosslink density; samples with high crosslink density failed cohesively within the silicone.
