Abstract: Aiming for developing green and environmental-friendly oil-water separation materials with
simple preparation processes, superhydrophilic composite membrane (TAPE membrane) was synthesized
using tannic acid (TA) and polyethylene glycol (PEG) as modifier, and polyvinylidene fluoride (PVDF) as
substrate membrane via simple impregnation method. The TAPE membrane obtained was then
characterized by SEM, AFM, FTIR, XPS and contact angle instrument, followed by analyses on its
oil-water separation performance, wear resistance and stability. The results indicated that the TAPE
membrane, displaying a porous micro-nano rough structure, had water contact angle and underwater oil
contact angle of about 0° and 156° respectively when TA content was 1.75% of the mass of distilled water,
which demonstrated the superhydrophilicity and underwater superoleophobicity. Moreover, the TAPE
2
membrane exhibited a flux of 1146.4 L/(m ·h), 30 times that of the unmodified PVDF membrane, for
separation of emulsion oil-in-water under work pressure of 0.09 MPa with the separation efficiency of
oil-water mixture and emulsion oil-in-water reaching 99.9%. In addition, the TAPE membrane showed
good stability with the water contact angle still maintained at as high as 152° after 25 times of sandpaper
detrition (320 mesh) under 100 g of loading.
Key words: tannic acid; polyethylene glycol; oil-water separation; superhydrophilicity; emulsion
oil-in-water; stability; functional materials
