Biomimetik Yaklaşımla Süperhidrofobik Yüzey Geliştirilmesi

Öz

Biomimetik yaklaşım, tasarım araştırmaları alanında yeni olanaklar sunmakta olup süperhidrofobik yüzey tasarımı bu alanlardan bir tanesidir. Bir yüzeyin geometrik ve kimyasal özellikleri süperhidrofobisite için belirleyici olan asli faktörlerdir. Bu çerçevede biomimetik yaklaşım, doğadaki süperhidrofobik bir yüzeyin geometrik özelliklerinin tasarlanan süperhidrofobik bir yüzeye aktarılmasında kullanılabilir. Tasarlanan modelin, belirlenen geometrik özelliklere sahip olacak şekilde imal edilebilmesi için uygun bir imalat yönteminin seçilmesi önemlidir. Yüzeyin gerekli kimyasal özelliklere sahip olabilmesi içinse malzeme seçimi önemli olmaktadır. Bu çalışmada, biomimetik yaklaşım kullanılarak süperhidrofobik yüzey imal edilmesi konusu ele alınmıştır. Bu çerçevede, süperhidrofobisite kavramının yıllar içinde gelişen teorik altyapısı incelenmiş olup üç boyutlu yazıcı ile model imal edilmesi, karbon nanotüp esaslı nanokompozit malzeme geliştirilmesi ve geliştirilen nanokompozit malzeme kullanılarak elektrospinning ile yüzey kaplanması işlemlerinden oluşan bir yöntemler bütününün süperhidrofobik yüzey imal edilmesinde uygulanabilirliği değerlendirilmiştir.

Superhydrophobic Surface Development with Biomimetic Approach

Abstract

Biomimetic approach provides new opportunities in the design research field, and superhydrophobic surface design is one of them. The geometrical and chemical properties of a surface are the main determinative factors for the superhydrophobicity. In this regard biomimetic approach, could be employed for transferring the geometrical properties of a superhydrophobic surface in the nature to a designed superhydrophobic surface. The selection of a suitable manufacturing method is important for manufacturing a designed model to have the specified geometrical properties. The selection of the material is important as for the surface to possess the required chemical properties. In this study, manufacturing a superhydrophobic surface by employing biomimetic approach is discussed. In this framework, the theoretical background of the superhydrophobicity concept that has emerged over the years is investigated; applicability of a set of methods for obtaining a superhydrophobic surface composed of the processes of manufacturing a model with a three-dimensional printer, developing a carbon nanotube-based nanocomposite material, and coating the surface by electrospinning using the developed nanocomposite material is evaluated.
