Gemiler üzerindeki biyolojik yüzey kirliliği direnç artışı, yakıt tüketimi artışı, GHG emisyonlarının artışı ve zararlı canlı türlerinin taşınımı gibi hem ekonomik hem de çevresel açılardan önemi artmakta olan bir problemdir. Gemi boyaları, gemi yüzeyindeki biyolojik kirlenmeyi azaltmak ve gemi yüzeyini pürüzsüzleştirmek için yaygın olarak kullanılmaktadır. Bu çalışma, gemilerde kullanılan antifouling boyalar ile ilgili yeni bakış açıları ve yaklaşımları tanıtmayı amaçlamaktadır. Çalışmada ilk olarak gemiler üzerinde oluşan yüzey kirliliği ve bu kirlenmeyi önleme yöntemleri kısaca anlatılmaktadır. Devamında boya / yüzey kirliligi hidrodinamiği ile ilgili son araştırmalar sunulmaktadır. Sonrasında ise antifouling boya teknolojisinde biyo-benzetim (biomimetic) yaklaşımı, bio-ilham (bio-inspired) antifouling boya stratejileri ve bio-ilham antifouling boyaların dizaynında karşılaşılan zorluklar detaylı olarak tartışılmaktadır. Gemi boyaları konusunda sürdürülen araştırmaların, insan yapımı deniz yapıları ve deniz yaşamı arasındaki uyumu korurken, gemi yüzey kirliliğinin etkili bir şekilde azaltılmasına olanak sağlayacağına inanılmaktadır.

Anahtar Kelimeler

Gemi boyaları, boya/yüzey kirliliği hidrodinamiği, biyo-benzetim.
