- Abstract
The study of functional and structural principles of some biological surfaces allows for their application in artificial man-made systems, a field called biomimetism. One of the most important attributes of the plant cuticle is hydrophobicity, it permits to overcome environmentally related physical and physiological issues, such as desiccation. This study describes ultrastructural features form the foliage of three species of Araceae by means of scanning electron microscopy (SEM) and a contact angle goniometer. This allowed us to id and describe certain patterns from the leaves surface of different species which present the lotus effect which in turn will help to explain it in order to generate knowledge that later may translate in materials that retain such behavior. Xanthosoma roseum, Xanthosoma sagittifolium and Philodendrun strictum samples were collected and studied, resulting surface contact angles were 146.34 ± 3.92°, 143.63 ± 0.42° and 138.32 ± 4.02°. Noteworthy, SEM images indicate a binary structure (micro and nanostructurally) for the above mentioned species which is similar to that oberved in similar studies. Frequently, these surfaces exhibit a self-cleaning property and are characterized by a high hydrophobicity (CA = 90° y < 150°) and water repellence where water drops roll rapidly over the leaves surface and thus eliminating an abundant number of dust particles adhered to them.
