漆酚改性氧化石墨烯膜的制备及性能研究

Preparation and properties study of urushiol modified graphene oxide membrane

本文以漆酚和氧化石墨烯为原料,通过简单的真空过滤和热处理制备了漆酚改性氧化石墨烯(GO)膜。漆酚-GO是通过GO表面环氧基团与漆酚中部分羟基发生反应制备的。然后通过加热,漆酚双键之间反应形成交联结构。通过改变漆酚与氧化石墨烯的质量比可以调控漆酚-氧化石墨烯复合膜的疏水性,并且复合膜可以用于油水分离。

Urushiol modified graphene oxide(GO) membrane was fabricated by a simple vacuum filtration which precedes to a thermal treatment on GO modified with urushiol.The urushiol-GO was prepared through the reactions between epoxy groups on GO surface and phenolic moiety of urushiol.The prepared urushiol-GO membrane was then heated to form the cross-linked structure by the reactions between the double bonds of urushiol.Hydrophobicity of the cross-linked GO membrane can be controlled by the ratio of urushiol/GO and it exhibited good oil/water separation efficiency.
