Curcumin based nanostructures exploration of environmental and aeronautical applications

Abstract

Over the years, various modifications have been made to graphene newlineoxide (GO) synthesis, yet there have been certain disadvantages in the newlineconventional methods of GO synthesis. On the other hand, curcumin is one of newlinethe most extensively researched polyphenolic compound, yet suffers certain newlinedrawbacks. Furthermore, the surface treatment techniques that are employed newlineto improve a material s characteristics is constrained by certain limitations. newlineAdvancements in nanotechnology could serve a variety of sectors, including newlineaerospace and industrial waste water treatment, in a wide range of ways. In newlinethe present investigation, we report the development of novel graphene oxide newlinenanosheets (GOCM) by pyrolyzing curcumin and bisdemethoxy curcumin newlineanalog quantum dots (BDMCAQD) by photo-oxidative plasma induced newlineirradiation process. The physicochemical, optical and electrochemical newlineproperties of the synthesized nanomaterials were characterized. The newlinesynthesized GOCM and BDMCAQD were then explored for their sensing newlineperformance in the detection of 1,4 dioxane and hydrazine respectively. newline The nanomaterial (GOCM and BDMCAQD) was then used as newlinedopant in the electrospun polyacrylonitrile (PAN) nanofibers and their newlineapplications in water treatment was studied. The fabrication process newlineparameters such as the dopant concentration, flow rate and spinning time for newlinethe development of PAN-GOCM and PAN-BDMCAQD nanofibers using the newlineelectrospinning technique were optimized by the statistical design of newlineexperiments (DoE) using TOPSIS based Taguchi L9 (33 newline) orthogonal array newlineapproach. The membrane performance studies (pure water flux (PWF), solute newlinerejection (SR), porosity, tensile strength (TS) and fouling rejection ratio newline(FRR)) were taken as the responses for the optimization process. newline
