Emerging chemical techniques for preparation of modern 2D materials lead inevitably to broadening the areas of practical applications on demand of the materials. One of the most bright trends in research and development of the most famous 2D material, graphene oxide, involves the search for optimal mass production, optimization and flexible adjustment of membrane materials for various practical needs as always based on unique structural and chemical features of graphene oxide itself. Here, physical chemical correlations between preparation history, structural peculiarities of graphene oxide and functional properties of graphene oxide-based membranes are reviewed and analyzed.
