Hydrophobicity was achieved by coating the membrane surface sublayer using conventional silicon material, which imitates the character of epicuticular wax (EW) of Prunus laurocerasus L. leaves. It was then applied as a separation medium in pervaporation (PV) of diluted mixtures of ethyl acetate and aroma compounds. The membrane's biomimetic characteristics were evaluated using surface morphology analyses, that is, Fourier transform infrared (FTIR), water contact angle measurements, and SEM imaging. A comparison of properties of the membranes synthesized in this work against selected hydrophobic plant leaves indicated a good agreement. PV using these biologically inspired artificial membranes demonstrated preference for the permeation of ethyl acetate. Besides intrinsic characteristics, it was also observed that the chemical potential is highly influential in activating sorption, diffusion, and desorption of a specific compound. 2014-04-21T02:28:44Z 2014-04-21T02:28:44Z 2013-02 Article Langmuir, vol. 29(5), 2013, pages 1510-1516 0743-7463 http://pubs.acs.org/doi/abs/10.1021/la3050253 http://dspace.unimap.edu.my:80/dspace/handle/123456789/33867 en American Chemical Society
