Since the fouling-releasing ability of silicone elastomers increased as their modulus decreases, we designed and prepared composites with embedded tiny NaC1 crytals that were soluble after their immersion in water, resulting in water-filled porous elastomers. The scanning electron microscope images confirmed such a designed water-filling porous structure. The existence of many micro-drops of water in these specially designed elastomers decreased the shear storage modulus and increased the loss factors. The decrease of shear modulus plays a leading role here and is directly related to a lower critical peeling-off stress of a pseudo-barnacle on them. Therefore, such a novel preparation with cheap salts instead of an expensive silicone provides a better way to make fouling-release paints with a lower modulus, a lower critical peeling-off stress and a better fouling-release property without a significant decrease of the cross-linking density.

On the basis of poly（Br-acrylate-alk yne）macroinitiator with two different initiating sites（alkyne and Br）,which is obtained by the RAFT homopolymerization of a new trifumctional acrylate monomer Br-acrylate-alkyne,we report here a facile synthetic approach to prepare poly（ethylene glycol）-g-poly（2,2,2-Trifluoroethyl methacrylate）（PEO-g-PFMA）hybrid dual brush polymer by one pot simultaneous ATRP polymerization and"click"*** two different kinds of brashes PEO and PFMA densely distributed on the same unit along the backbone,spin-cast dun film of the hybrid dual brush polymer PEO-g-PFMA exhibited a synergistic anti-fouling property,the PEO brush endow the surface with a non-fouling characteristic while the PFMA brush exhibit fouting-release functionality with their low surface *** by protein adsorption and cell adhesion tests provided estimates of the anti-fouling activity of hybrid dual brush polymer surfaces,which was examined to be influenced by the degree of polymerization（DP）of the backbone,the molecular weight of PEO and the PFMA brush *** compositional heterogeneities,the hybrid dual brush polymer surfaces show considerable ann-fouling performance.

关键词： one pot hybrid dual brush polymer non-fouling fouling-release spin-casting anti-fouling surfaces
