Polyvinyl alcohol (PVA)is swelling and poor stability when it is made of membrane material

however

graphene oxide (GO)has good chemical stability. PVA/GO composite membranes with different GO content are prepared in this research

and PVA as the main raw material

GO for additives

PEG as the pore

adopting blending method. The hydrophilicity and pure water flux of the membrane are measured by the optical contact angle measuring instrument and the ultra filtration cup

and morphology

thermal and mechanical properties are characterized by SEM

IR

TGA and so on. The results showed that:addition of GO improve the internal channel

the hydrophilicity

anti-fouling property and the pure water flux

meanwhile

the thermal stability and mechanical properties of the membrane are improved. When the content of GO was 2%

the comprehensive performance of the membrane is optimized.
