conversion coatings of Mg-alloy AZ91D using trihex.l(tetradecyl) phosphonium bis(trifluoromethanesulfonyl)amide ionic liquid

Science china chemistry 2012年第8期55卷 1598-1607页

作者： HOWLETT P. c. GRAMET S. lin j. EFTHIMIADIS j. cHEN x. B. BIRBILIS N. FORSYTH M. ARc centre of Ex.ellence for Electromaterials Science Institute for Frontier Materials Deakin Univerxlty Burwood Campus Burwood Victoria 3125 Australia cAST cooperative Research centre Department of Materials Engineering Monash University Melbourne Victoria 3800 Australia

This work reveals the performance of a trihex.l(tetradecyl)phosphonium bis(trifluoromethanesulfonyl)amide ([P6,6,6,14][NTf2]) ionic liquid (IL) conversion coating upon AZ91D. Such conversion coatings represent a novel avenue for chromate replacement. An optimization of coating performance was pursued by careful alloy pretreatment to generate a surface on which the coating performs best, as the AZ91 substrate is distinctly different from pure or dilute Mg alloys. The results reveal that a functional conversion coating can be achieved, retarding anodic dissolution kinetics, causing a significant decrease in corrosion rate. The coating efficacy is closely tied to the pretreatment performed, which dictates both the microstructural and electrochemical heterogeneity of the surface. The resulting coatings were found to contain Mgx.x.and phosphonium cation related components, the proportions of which were dependent on the pretreatment.

conj.gated polymers are promising material candidates for many future applications in flex.ble displays, organic circuits, and sensors. Their performance is strongly affected by their structural conformation including both electrical and optical anisotropy. Particularly for thin layers or close to crucial interfaces, there are few methods to track their organization and functional behaviors. Here we present a platform based on plasmonic nanogaps that can assess the chemical structure and orientation of conj.gated polymers down to sub-10 nm thickness using light. We focus on a representative conj.gated polymer, poly(3,4-ethylenediox.thiophene) (PEDOT), of varying thickness (2-20 nm) while it undergoes redox.in situ. This allows dynamic switching of the plasmonic gap spacer through a metal-insulator transition. Both dark-field (DF) and surface-enhanced Raman scattering (SERS) spectra track the optical anisotropy and orientation of polymer chains close to a metallic interface. Moreover, we demonstrate how this influences both optical and redox.switching for nanothick PEDOT devices.
