摘要

成膜材料聚乙烯醇（PVA）易溶胀，稳定性差，氧化石墨烯（GO）具有很好的化学稳定性，以PVA为主要原料，GO为添加剂，聚乙二醇为造孔剂，采用共混法制备了GO含量不同的PVA/GO分离膜，并用光学接触角测量仪、超滤杯等考察了分离膜的亲水性和耐污染性；采用SEM、IR、TGA等表征了分离膜的微观形貌、热学及力学性能。结果表明：GO的加入改善了分离膜的内部孔道、亲水性、纯水通量和耐污染能力，膜的热稳定性和力学性能均得到提高，当GO含量为2%时，分离膜的综合性能达到最优。

Abstract

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

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.
