Abstract:
A method of modifying a hydrophobic surface of a polymeric substrate to reduce biofouling of the surface, said method comprising:(a) providing a biofouling resistant surfactant composition comprising polyalkylene oxide surfactant molecules, the surfactant molecules comprising a hydrophobic domain sufficient to promote adsorption of the surfactant molecules on the hydrophobic surface of the polymeric substrate and a modified portion wherein at least a portion of the polymeric surfactant molecules is modified with a nonreactive end group that has a stable charge over a pH range of about 2 to 12 and (b) contacting at least a portion of said hydrophobic surface with the biofouling resistant surfactant composition after step (a).
