실리콘 폴리 우레아 수지를 활용한 방오도료 연구

다국어 초록 (Multilingual Abstract)

Biofouling is the undesirable accumulation of marine organisms such as benthic microorganisms,
plants, algae, mollusks on a man-made structure. They can increase both the hydrodynamic volume
and the frictional effects leading to increased drag of up to 60% when they accumulate on the
surface of ship hull. Antifouling (AF) coatings use in ship hulls, fish nets and other marine
structures to avoid those problems. However, the coating designed with organic or inorganic
substances which are not only attached fouilng organisms but attacking to non-target marine
species. This study, the antifouling candidates of hexadecanol, octanol, thymol and hemogrlobin
formulated with low frictional copolymer of silicon polyurea that were screened for antifouling
activities. In the result of antibacterial activity, all of the AF candidates had activities showed the
clear clean zone. Most activity was ocatdecanol which had 4.7 times higher than others. The test
of antimicroalgal activity used in microalgae Navicula cancellata. Hexadecanol was 0.25 times higher
than control. Attachment test of macroalgal spores of Ulva intestinalis, four AF candidates had
strong activity which showed no spore attachments. Further studies are needed to investigate the
AF mechanism of those candidates to use it most effectively in environmentally acceptable AF
coatings.
