Abstract:Membrane separation technology is a widely used process modification technology, especially in wastewater treatment. Graphene oxide (GO) nanosheets, as a novel single-atom-thick two-dimensional structural material with abundant oxygen-containing functional groups, have attracted a large number of researchers to apply them to the study of membrane modification. This paper introduces the modification method of GO/PVDF composite membrane, and the detailed analysis of the authors, keywords, number of articles, and citation frequency of the literature published during the 10 years using VOSviewer visualization analysis based on the relevant literature information about graphene oxide membranes in Web of science database from 2010 to 2020, to study the research in this field during the 10 years. The research progress of graphene oxide membranes and their preparation methods are described.

是極为重要的工艺改造技术,特别是在污水处理方面其优势日益彰显。近年来,采用有机高分子聚合物(如聚偏氟乙烯PVDF)为膜材料制备具有分离功能的新型膜最为常见,有机高分子膜具有成本低、膜容易被改性、工艺简单等优点。但由于高分子聚合材料的高疏水性能限制了其在污水处理领域的应用,污染物容易粘附在膜表面并严重堵塞膜孔,降低膜通量和抗污能力[1]。已有大量研究表明,亲水改性有利于减少膜污染,防止膜通量下降[2]。利用氧化石墨烯(graphene oxide,GO)制备新型复合膜引起了国内外越来越多人的关注,主要因为其作为一种新型的单原子厚度的二维结构材料,具有丰富的含氧官能团(如羧基、羰基、环氧基和羟基)、比表面积大,是一种低密度、高强度的材料[3],可被广泛运用于膜改性中。……
