Silver nanofibres by a novel electrospinning process: Nanofibres with plasmon resonance in the ir region and thermal hysteresis electricalFeaturesConductivity

摘要

In this study, we have introduced electrospmning of a colloidal solution rather than the conventional sol-gcsl process as a novel strategy to produce silver nanofibres. Typically, a silver acetate/polyvinyl alcohol colloidal solution was successfully electrospun. Electrophoretic light: scattering (ELS) and dynamic light: scattering (DLS) analyses have affirmed that, the olocfrospuri solution is a colloid with a ξ-potential of -2 mV and average particle diameter of 373 ± 1 nm. Moreover, FTIR analysis affirmed that neither the polymer nor silver acetate nanoparticles were: affected during the electrospinning process. Calcination of the electrospun mats at 700 °C in an argon atmosphere produced smooth and unbroken pure silver nanofibres. Surface plasmou resonance of the resultant silver nanofibres was detected at. 962 nm which is biologically beneficial. Furthermore, the synthosised silver nanofibres revealed thermal hysteresis in the electrical conductivity properties. These advantageous physical features strongly suggest utilising the prepared nanofibres in various fields.
