GO is easily dispersed in solvents, dielectric property, transparency, electronic features can be adjusted due to the superior mechanical properties and areas of use are expanding day by day. In this study, graphene oxide was obtained from graphite by using modified Hummers method and then applied to polyester fabric surface according to multilayer coating method. Contrary to the traditional Hummers method in the literature, this study was carried out without the use of NaNO₃ in order to be environmentally friendly. Based on the Layer-by-Layer coating method, GO based nano films have been applied to the polyester fabric surface. After obtaining the GO based nanocomposite polyester fabrics, it was treated with Na₂S₂O₄ and NaBH₄ in order to obtain RGO structure and GO reduction was achieved. A thin coating layer was observed in SEM analysis of the reduced graphene oxide (RGO) and GO coated fabrics. In the EDS analysis, increase in the amount of C and the decrease in the amount of O were determined after the reduction process. The most striking feature of graphene oxide was applied to all fabrics with a 4-probe measuring device and the best result was observed in the polyester fabric which was coated with Na₂S₂O₄ in 10 layer 5 minutes with Layer-by-Layer coating method with 1.47 × 1̄0 ³ S/cm².

The paper presents a comparison of the techniques for polydecylmethylsiloxane selective layer coating to the inner and outer sides of a polysulfone hollow fiber support. It has been shown that coating to the outer side allows one to obtain a composite membrane with a higher selectivity for CO2/N2 vapor. A decrease in the number of defects in the selective layer is achieved by increasing the viscosity of the polydecylmethylsiloxane solution. The resulting membrane was characterized in the separation of a model mixture of hydrocarbons, and a high separation selectivity was shown - 12.4 with respect to the n-butane / methane gas pair.

New Applications

Abstract The plasma transferred arc process continues to be the coating method of choice for the application of cobalt base alloys onto valve and valve trim. Although new applications have been developed over the years, the process remains largely associated with the application of high performance, highly alloyed powders for relatively small parts or small areas of large parts. The use of the plasma transferred arc process for large volume application has been limited by the robustness and performance characteristics of the equipment and the use of cobalt. A new plasma transferred arc system (power source, torch and process controller) has been developed which allows the application of powder metal alloys at deposition rates of up to 40 pounds per hour. In addition, there has been a development of new non-cobalt powder alloys with excellent mixed corrosion and wear resistance properties. These capabilities have rendered the process technically and economically viable for large and demanding applications in the mining, power utility and steel industries. The new PTA system and the recent developments in powder alloys will be discussed. Reference will be made to specific applications in target industries.
