Research on Hydrophilicity and Microstructure of Several Plant Leaves

Article Preview

Abstract:

This paper studied wettability of several typical plant leaves such as abutilon, Jerusalem artichoke and sunflower, contact angle of several leaves were measured through the contact angle measuring instrument, which were 41.5°, 46.3°and 43.6°respectively. Microstructure of abutilon, Jerusalem artichoke and sunflower leaves were observed by scanning electron microscopy, It found that several typical plant leaves are composite structure of micron scale and nanoscale, covered some long needle-like spikes, this feature has an important influence on hydrophilicity. According to wenzel model, the paper analyzed the relationship between hydrophilicity and microstructures of several plant leaves.
