Laminated, Composite and Sandwich Membranes Based on Graphene-Oxide with Nano-Textiles

Abstract

The results of gas and ion separation are influenced by diffusion speed [18], layer investing [19], spacing between nano-particles of GO providing channels (Figure 1), gap size between the layers. The functional groups also expand separation abilities and possibilities. Examples of selective separation AbstractThe contribution describes preparation of graphene-oxide suspensions and their hybrid compounds, GO-biochar, GO-C 60 , GO-CF 0.9 , which are subsequently applied to nano-textiles using various techniques. This method was used to prepare composite and sandwich-type films or laminated nano-textiles. Relative arrangement in product (film) crosssections was identified in products prepared using SEM analysis. Thermal stability of the products was determined using DTA, DSC analysis and compared to the stability of the nano-textiles. Chemical properties of graphene-oxide (GO) allow a number of its modifications, partial reduction, creation of composites with metals and their oxides. Preparation and thermal analysis GO-TiO 2 / PCl /GO-TiO 2 has been described as an example. The conclusion of the project suggests possible application of the products (films).
