The cuticula is a main part of the evolutionary progress of terrestrial plants. It consists of an insoluble polymer fraction and a soluble lipid (wax). Those waxes are crystalloid micro- and nanostructures with a high structural and morphological diversity and can rearrange in a self-organized manner. The platelets, tubules, filaments etc. are forming based on their chemical composition and share the ability to regenerate. In order to utilize those properties, structured polymer substrates are produced with the target of adhesion and recrystallization of vaporized plant waxes. By tuning the chemical properties of the waxes as well as the surficial ones of the substrates, the shape and orientation of the crystals can be manipulated to the intended usage. In this project, environmental pollutant adhesion is targeted. The influence of surface-structured polymers on the wax crystallization is compared to flat substrates and the difference in grade of adhesion is analyzed and quantified. The aim is to generate an optimized material adhesion system. By separation and regeneration of the waxes or by the use of embedded catalysts, harmful air contaminants are sought to be decimated.
