The present invention relates to compounds and materials that reduce the accumulation of microorganisms on a surface by interfering with the attachment of the organisms to the surface. The compounds and materials of the present invention are thus useful in preventing the formation of biofilms. The compounds of the present invention may be either adhered to a surface or integrated within a polymer. Surfaces coated by the present invention are resistant to biofilm formation, in part due to the smoothness of the surface coated with the present invention.

1. A surface resistant to biofilm formation, wherein the substrate surface resistant to biofilm formation is made by: coating a substrate surface with a curable composition consisting of a monomer of Structure A wherein R′, R″, or R′″ represents Chlorine, Bromine, Hydrogen or an organic moiety selected from the group consisting of alkyl, aryl, alcoholic, etheric, thioesteric, esteric, amido, amino, thiyl, urethane and acid anhydride;R″″ represents Hydrogen or a Methyl group wherein one or more of R′, R″, or R′″ is Chlorine, Iodine, or Bromine;Z represents Oxygen or one of said organic moieties wherein one Oxygen binds said organic moiety to the aryl group and another Oxygen binds said organic moiety to the carbonyl adjacent to the alkene to form the acrylate, wherein R″″ is a hydrogen, or methacrylate, wherein R″″ is a Methyl group;mixing the curable composition with an acrylate or methacrylate compatible coating and an initiator; andcuring, through chain growth polymerization, said curable composition and acrylate or methacrylate compatible coating by the addition of an energy source onto said substrate surface for free radical polymerization and wherein the surface substrate is either solid or liquid, said surface being permanent and durable to resist biofilm formation, said curable composition unable to diffuse into and adversely affect a majority of multicellular organism's biological functions. 2. The surface of claim 1, wherein said monomer is a mono- or multi-functional in the number of polymerizable groups, selected from the group consisting of acrylates, methacrylates, thiols, alkenes and alkynes, to which the monomer is covalently bound. 3. The surface of claim 1, wherein said biofilm resistant polymer has a roughness that approximates that of electropolished stainless steel. 4. The surface of claim 1, wherein polymerization of said monomer to said surface renders said surface with a smoothness wherein the peak to valley ratio of the surface has a value of approximately 1 μm. 5. A surface resistant to biofilm formation, wherein the substrate surface resistant to biofilm formation is made by: coating a substrate surface with a curable composition consisting of a monomer of Structure C: wherein R1, R2, R3, R5, or R6 represents Chlorine, Bromine, Hydrogen or an organic moiety selected from the group consisting of alkyl, aryl, alcoholic, etheric, thioesteric, esteric, amido, amino, thiyl, urethane, and acid anhydride;R4 represents Hydrogen or a Methyl group wherein one or more of R1, R2, R3, R5, or R6 is Chlorine, or Bromine;Z represents Oxygen or one of said organic moieties wherein one Oxygen binds said organic moiety to the aryl group and another Oxygen binds said organic moiety to the carbonyl adjacent to the alkene to form the acrylate, wherein R4 is a hydrogen, or methacrylate, wherein R4 is a Methyl group;mixing the curable composition with an acrylate or methacrylate compatible coating and an initiator; andcuring, through chain growth polymerization, said curable composition and acrylate or methacrylate compatible coating by the addition of an energy source onto said substrate surface for free radical polymerization and wherein the surface substrate is either solid or liquid, said surface being permanent and durable to resist biofilm formation, said curable composition unable to diffuse into and adversely affect a majority of multicellular organism's biological function.
