Preparation and characterization of luminescent polycarbonate nanofibers embedded with surface capped CdS nanoparticles

Abstract

As an important engineering material with tremendous utilities, polycarbonate (PC) and its composites are contributing a major role among highly useful materials. Preparing ultrafine fibers with defect free surface morphology is a challenge in the field of nanotechnology. In the present work ultrafine bead free PC fibers with average diameter very close to 100 nm were prepared by optimizing various spinning parameters during electrospinning fiber fabricating technology. At the same spinning conditions PC nanocomposite fibers were prepared by incorporating surface modified cadmium sulphide (CdS) nanoparticles with prominent optical properties. The prepared PC-CdS nanocomposite fibers have excellent absorption and emission properties and also exhibit semi-crystalline nature. By increasing the nanoparticle concentration there was remarkable improvement in the thermal stability of the PC nanocomposite fibers.
