Abstract：

O-phenylenediamine (OPD), m-phenylenediamine (MPD) and p-phenylenediamine (PPD) were selected for covalently modifying graphene oxide (GO) sheets to prepare phenylenediamines modified GO membranes by vacuum filtration, and the effects of three phenylenediamines on the structure and properties of GO membrane were studied. The results show that phenylenediamines of different structures have different modification effects on GO: OPD has low reactivity and consumes less oxygen-containing functional groups of GO, which can effectively extend the interlayer distance (d-spacing) of GO membrane; MPD consumes more oxygen-containing functional groups of GO than OPD, and also increases the d-spacing of GO membrane; PPD consumes most of GO oxygen-containing functional groups due to high reactivity of the para-amino group, resulting in the accumulation of the GO sheets, and there is no significant change in the d-spacing of GO membrane. Pervaporation separation performance of three modified membranes for 90 wt% ethanol/water system shows that the permeation flux of OPD, MPD and PPD modified GO membranes are 0.55 kg/(m2?h), 0.56 kg/(m2?h) and 0.42 kg/(m2?h), the separation factor are 90.58, 30.78 and 34.49, respectively. It is proved that phenylenediamines have certain modification effects on GO.
