以间苯二胺(MPD)为水相单体、均苯三甲酰氯(TMC)为油相单体，氧化石墨烯（GO）作为水相添加物，采用界面聚合法，制备了GO-PA（聚酰胺）/PSF（聚砜）混合基质反渗透复合膜。采用扫描电子显微镜表征了膜形貌，考察了该膜对氯化钠的截留性能及耐氯性。结果表明，聚酰胺反渗透膜填充氧化石墨烯后，其分离性能优于聚酰胺膜，且具有较好的耐氯性。随着氧化石墨烯含量的增加，膜的通量增大，当添加量为0.005 %时，膜具有最大通量，为63 L/(m²·h)。

Grephene oxide (GO) mixed matrix reverse osmosis (RO) membranes were prepared with metaphenylenediamine(MPD) and trimesoyl chloride (TMC) by interfacial polymerization. Themorphology of the membraneswere characterized by scanning electron microscopy(SEM). The separation performance and chlorine resistance were also investigated.The results shown that owing to the hydrophilicity of GO, the membranes appeared to be more hydrophilic and had higher pure water fluxes than the bared polyamide RO membrane,only with a slight change of rejection. When the content of GO added in the aqueous phase was 0.005wt%, the flux of the membrane increased by 20%. The mixed matrix RO membrane of polyamide and GO shownbetterchlorine resistance than PA RO membrane.
