Latest Patents
Dhanraj Shinde's latest patents focus on the method of manufacturing proton selective membranes based on two-dimensional materials. The first patent describes a proton conductive membrane that includes a proton selective layer composed of 80-100% carbon with sp2 hybridization. This layer has a thickness ranging from 0.3 to 100 nm and may contain 0-20% of hydrogen, oxygen, nitrogen, and sp3 carbon. The sp2 carbon is presented in the form of graphene-like material, featuring 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.
