Hydrophilic Mechanism of Sunflower Leaves and Simulation Research

Article Preview

Abstract:

This paper studied wettability of sunflower leaves, contact angle of sunflower leaves were measured through the contact angle measuring instrument, which was 43.6°. Microstructure of sunflower leaves were observed by scanning electron microscopy, It found that sunflower leaves is micro and nanostructures covered some needle-like spikes, this feature has an important influence on its hydrophilicity. Through Matlab software hydrophilic mechanism of sunflower leaves was carried out the simulation study, roughness factor γ and area ratio plays an important role to its wettability, which can increase hydrophilicity of the solid surface.
