Acrylic polyols with polyethylene glycol (PEG) side chains (BOH) were synthesized with allyl polyethylene glycol (APEG)

methyl methacrylate (MMA) and butyl acrylate (BA).The α

ω-triethoxysilane terminated PDMS oligomer (TSU)

and α

ω-triethoxysilane terminated PFPE oligomer (PFU) were synthesized

respectively.Then the oligomers were mixed together to prepare the crosslinked-network coatings by condensation reaction.The chemical composition of the as-prepared copolymer was characterized by 1H-NMR and FTIR.Surface energy

elastic modulus and the biological fouling properties of the coatings were measured by the X-ray photoelectron spectroscopy

contact angle (water and diiodomethane)

nano mechanical test instruments and biofouling assays.The effects of the surface energy

elastic modulus and biological fouling properties of the copolymer were investigated.The results showed that the crosslinked network coatings had both lower surface energy attributed to fluorine and silicone elements

and better antifouling properties thanks to PEG side chains.Thus their antifouling properties were better when comparing with hydrophilic BOH and the commercial sample DC 3140.
