DEVELOPMENT OF NOVEL FUNCTIONAL COPOLYMERS AND SURFACES WITH PERMANENT AND/OR CONTROLLED RELEASED BIOCIDAL SPECIES

Abstract: 

Novel environmentally acceptable biocidal polymeric materials represent a very important field of basic research related with modern technological demands, such as the development of clean surfaces for sensitive sanitary applications or alternative antifouling paints in marine applications. Within this frame, an interdisciplinary approach is proposed, through the collaboration of three research groups, comprising researchers from four established institutes and an invited researcher with complimentary expertise.

We propose the development of novel polymeric materials exhibiting controlled organization and biocidal activity in the solid state. These materials will be based on amphiphilic copolymers with a diblock or comb-like architecture, as well as on homopolymer or mixed polymeric brushes. To realize these architectures, living/controlled polymerization techniques, like Atom Transfer Radical Polymerization or Group Transfer Polymerization, as well as grafting approaches, will be exploited.

The main functionality aimed at the solid state is the inhibition of microorganisms' growth. This will be achieved via the introduction of environmentally-friendly biocidal groups like ammonium- or phosphonium-type surfactants, as well as zwitterionic species along the polymer chains. The effectiveness of the novel materials will be controlled by their organization in the solid state or the method of attachment (electrostatic vs covalent) of the biocidal groups. Moreover, ˜self-polishing properties will be aimed using exchangeable or hydrolyzable biocidal species.

Special efforts will be given on the characterization of the novel biocidal surfaces, in terms of their self-polishing behavior, release of biocidal species and testing the effectiveness of the materials under enhanced biofouling conditions. Moreover, in collaboration with a paint manufacturer, field tests will be performed and the potential applicability of the novel materials in marine paints will be evaluated.
