Abstract: A biocide-encapsulated microcapsule for use in paint includes a hydrophobic core formed by polymerization of a hydrophobic monomer comprising an unsaturated bond in presence of a free radical initiator; a cross-linking hydrophilic shell adapted to enclose the hydrophobic core and formed by polymerization of a hydrophilic monomer comprising an unsaturated bond and another cross-linking agent; and a biocide being a hydrophobic compound. The hydrophobic core and the cross-linking hydrophilic shell enclose the dispersed biocide. Therefore, the biocide is released from the microcapsule core in the long term such that a resultant dried paint prevents biofouling in the long term.

Abstract: A biocide-encapsulated microcapsule for use in paint includes a hydrophilic core formed by polymerization of a hydrophilic monomer comprising an unsaturated bond in presence of a free radical initiator; and a biocide being a hydrophobic compound. The hydrophilic core encloses the dispersed biocide to effect storage and releases of the biocide. Therefore, the biocide is released from the microcapsule core in the long term such that a resultant dried paint prevents biofouling in the long term.
