“…A comparison of receding contact angle against spore settlement has been done for a number of amphiphilic and non-amphiphilic polymer surfaces by Grozea and Walker [66]. The study clearly shows that receding contact angle is not the only surface property that mediates spore settlement and there exist classes of surfaces where such a correlation is not valid.…”

This review article summarizes some recent insights into the strategies used by marine organisms to select surfaces for colonization. While larger organisms rely on their sensory machinery to select surfaces, smaller microorganisms developed less complex but still effective ways to probe interfaces. Two examples, zoospores of algae and barnacle larvae, are discussed and both appear to have build-in test mechanisms to distinguish surfaces with different physicochemical properties. Some systematic studies on the influence of surface cues on exploration, settlement and adhesion are summarized. The intriguing notion that surface colonization resembles a parallelized surface sensing event is discussed towards its complementarity with conventional surface analytical tools. The strategy to populate only selected surfaces seems advantageous as waves, currents and storms constantly challenge adherent soft and hard fouling organism.

“…There has been a significant effort to develop environmentally benign, non-toxic fouling-release and/ or non-fouling coatings for use on marine craft (see reviews by Genzer and Efimenko 2006;Krishnan et al 2008;Grozea and Walker 2009). Silicone elastomers such as polydimethylsiloxane elastomer (PDMSE) have been the most successful of these coatings, which 'release' accumulated macrofouling under suitable hydrodynamic conditions (Kavanagh et al 2005;Wendt et al 2006).…”

Barnacle settlement and the adhesion of protein and diatom microfouling to xerogel films with varying surface energy and water wettability

Previous work has shown that organosilica-based xerogels have the potential to control biofouling. In this study, modifications of chemistry were investigated with respect to their resistance to marine slimes and to settlement of barnacle cyprids. Adhesion force measurements of bovine serum albumin (BSA)-coated atomic force microscopy (AFM) tips to xerogel surfaces prepared from aminopropylsilyl-, fluorocarbonsilyl-, and hydrocarbonsilylcontaining precursors, indicated that adhesion was significantly less on the xerogel surfaces in comparison to a poly(dimethylsiloxane) elastomer (PDMSE) standard. The strength of adhesion of BSA on the xerogels was highest on surfaces with the highest and the lowest critical surface tensions, g C and surface energies, g S , and duplicated the 'Baier curve'. The attachment to and removal of cells of the diatom Navicula perminuta from a similar series of xerogel surfaces were examined. Initial attachment of cells was comparable on all of the xerogel surfaces, but the percentage removal of attached cells by hydrodynamic shear stress increased with g C and increased wettability as measured by the static water contact angle, y Ws , of the xerogel surfaces. The percentage removal of cells of Navicula was linearly correlated with both properties (R 2 ¼ 0.74 for percentage removal as a function of y Ws and R 2 ¼ 0.69 for percentage removal as a function of g C ). Several of the aminopropylsilyl-containing xerogels showed significantly greater removal of Navicula compared to a PDMSE standard. Cypris larvae of the barnacle B. amphitrite showed preferred settlement on hydrophilic/higher energy surfaces. Settlement was linearly correlated with y Ws (R 2 ¼ 0.84) and g C (R 2 ¼ 0.84). Hydrophilic xerogels should prove useful as coatings for boats in regions where fouling is dominated by microfouling (protein and diatom slimes).

“…Fluorosilicones showed excellent release of the green seaweed, Ulva, and barnacles compared to the control silicone (Marabotti et al 2009), although the release of diatoms was not improved (unpublished data). In the last few years, a widely researched strategy to improve the FR properties of polymers consists of combining hydrophobic, low surface energy fluorinated moieties with hydrophilic poly(ethylene glycol) (PEG) segments in the same coating (Gudipati et al 2005;Krishnan et al 2008;Martinelli et al 2008;Grozea and Walker 2009;Park et al 2010). PEG is well known for its resistance to protein adsorption and cell adhesion (Mrksich and Whitesides 1997;Walton et al 1997;Li et al 2005).…”

Amphiphilic block copolymer/poly(dimethylsiloxane) (PDMS) blends and nanocomposites for improved fouling-release

et al. 2011

View full text Add to dashboard Cite

Amphiphilic diblock copolymers, Sz6 and Sz12, consisting of a poly(dimethylsiloxane) block (average degree of polymerisation ¼ 132) and a PEGylated-fluoroalkyl modified polystyrene block (Sz, average degree of polymerisation ¼ 6, 12) were prepared by atom transfer radical polymerization (ATRP). Coatings were obtained from blends of either block copolymer (1-10 wt%) with a poly(dimethylsiloxane) (PDMS) matrix. The coating surface presented a simultaneous hydrophobic and lipophobic character, owing to the strong surface segregation of the lowest surface energy fluoroalkyl chains of the block copolymer. Surface chemical composition and wettability of the films were affected by exposure to water. Block copolymer Sz6 was also blended with PDMS and a 0.1 wt% amount of multiwall carbon nanotubes (CNT). The excellent fouling-release (FR) properties of these new coatings against the macroalga Ulva linza essentially resulted from the inclusion of the amphiphilic block copolymer, while the addition of CNT did not appear to improve the FR properties.
