Title: Innovations of Inventor Sergei Smirnov
Introduction
Sergei Smirnov is a notable inventor based in Las Cruces, NM (US). He has made significant contributions to the field of materials science, particularly in the development of proton selective membranes. With a total of six patents to his name, his work is recognized for its innovative approach to enhancing proton conductivity.
Latest Patents
Among his latest patents is a method of manufacturing proton selective membranes based on two-dimensional materials. This proton conductive membrane features a proton selective layer composed of 80-100% carbon with sp2 hybridization, having a thickness ranging from 0.3 to 100 nm. The membrane includes 0-20% of hydrogen, oxygen, nitrogen, and sp3 carbon, with the sp2 carbon existing in the form of graphene-like material. The proton selective layer is designed with a plurality of pores formed by 7, 8, 9, or 10 sp2 carbon cycles, with effective diameters of up to 0.6 nm. An ionomeric polymer layer is applied on top of the proton selective layer, and the total thickness of the membrane is less than 50 microns. The ionomeric polymer can be PFSA (perfluorinated sulfonic acid), PVP (polyvinylpyrrolidone), or PVA (polyvinyl alcohol) with iodide or bromide counterions dissolved inside. The graphene-like material can be CVD graphene or reduced graphene oxide (rGO), and the D to G Raman band ratio of the membrane exceeds 0.1.
