Inhibition of bacterial adhesion on well ordered comb-like polymer surfaces

Wettability of the morphologically and compositionally varied surfaces prepared from blends of well ordered comb-like polymer and polystyrene

“…S1 of Supplementary material [43]. In addition, the surface energy of CH 3 -10SE (%20 mN/m) is much lower than that of PS (%42 mN/m), as reported previously, due to the well ordered structures of alkyl side chains of CH 3 -10SE oriented perpendicular to the surface [35][36][37][38]. Therefore, polymeric surfaces with various morphologies and wettabilities could be prepared by blending these polymers with quite different surface energies.…”

“…The polymer films spin-coated on a glass or a silicon wafer have double layered lamellar structures in which the ordered layers are parallel to the substrate surface and their side chains are almost perpendicularly oriented to the surface [35][36][37][38]. As a result, these polymers exhibit very low surface energies in the 21-23 mN/m range [38], which is close to those of the silicone polymer, such as poly(dimethylsiloxane) (PDMS), and a fluoropolymer, such as poly(tetrafluoroethylene) (PTFE). This study examined the potential of the comb-like polymer, CH 3 -10SE (Fig.…”

PDMS-based porous particles as support beds for cell immobilization: Bacterial biofilm formation as a function of porosity and polymer composition

“…Krishnan et al [16] described the anti-biofouling properties of surfaces containing amphiphilic side chains which influence the adhesion of microorganisms. Sohn et al [17] reported that bacterial adherence after 24 h was much lower when using a non-polar surface (poly(oxyethylene) derivatives) in comparison with normal PDMS. Satriano et al [18] found that the presence of hydrophilic SiO 2 -like holes within hydrophobic polyhydroxymethylsiloxane (PHMS) favours bacterial cell attachment with respect to the pure PHMS non-polar surface, and Bertin et al [19] reported that an aerobic coculture had better performance on the bioremediation of organic pollutants when adsorbed onto silica beds than when fixed on nonpolar polyurethane foams.…”

Surface properties and liquid crystal alignment behavior of poly(2-hydroxyethyl methacrylate) derivatives with alkyl ester side chains

“…Therefore, the critical side chain length which can generate the ordered structures is varied according to the backbone structure and linking group; it was reported that the critical number of methylene units of poly(-alkyl sulfonyl oxyethylene)s, poly(alkyl vinyl ether)s, poly(alkyl acrylate)s, poly(alkyl styrene)s, and poly(alkyl methacrylates)s was reported to be 5, 8, 9, 10, and 12, respectively at the bulk state [19][20][21][22][23]. Although wetting properties of the comb-like polymers with ordered structures are influenced by orientations of alkyl side chains, those of the polymers with disordered structures are controlled by the backbone and linking groups [24,25].…”
