摘要：
In the present study, a facile coating deposition method has been used to modify PVDF (polyvinylidene fluoride) membrane for the separation of emulsion oil. Natural polyphenol (tannic acid) and tetraethylenepentamine were employed to prepare PVDF-modified membrane which shows improved hydrophilicity and underwater oleophobic property as compared to native PVDF membrane. The effects of mass ratio, phenolic concentration and coating time onto porous membrane were investigated to achieve optimum efficiency of membrane. Significant chemical stability of the modified membrane established its applicability for water flux permeation and separation of emulsion oil.
