Abstract
The super-hydrophobic and super-oleophilic properties of taro leaves and their application were reported.The reasons that taro leaves possess super-hydrophobic and super-oleophilic properties were analyzed by static contact angle(CA) and scanning electron microscopy(SEM).The saturated oil absorption rate,sustained release and centrifugal oil retention of taro leaves dried at different temperatures were measured and analyzed by weighing method,sustained release property and centrifugation etc.The results show that the reverse side of the taro leaf is super-hydrophobic and its static water contact angle can reach 157.1° which is much larger than that of the front one(109.1°),and the sliding angles are not larger than 3°.It is also observed that the change of saturated oil absorption rate for the taro leaves shows certain regularity,and the highest saturated oil absorption(8.1 g / g) was obtained while the taro leaves dried at 200 ℃.Taro leaves own different capacity on fixing various oil spill.It can be known from results that taro leaves have strong capacity on fixing low volatile oil material and high centrifugal oil retention at high rotate speed.
