Electrospinning of Antimony Doped Tin Oxide Nanoparticle Dispersion for Transparent and Conductive Films

Stable dispersion of antimony-doped tin oxide nano-powder was prepared by wet attrition process by comminuting aggregated ATO nano-powder using the titanate coupling agent as a dispersant to form the chemisorbed layer on the particle surface. The feed solution of the ATO dispersion and PVP was prepared for electro-spun fibers on the glass substrate. The surface resistance of the fibrous ATO film after electrospinning for 30 minutes was in the order of 105 Ω/□, which is sufficient for anti-static coating. The optical transmittance of ATO fibers was confirmed by measuring the visible light transmittance.

Surface modifications of an AlN ceramic under an UV excimer laser irradiation have been investigated by SEM observations and EDS analysis, grazing-XRD and electrical resistance measurements. XRD have revealed the presence of an Al metallic film upon the laser impacted zone and SEM+EDS analysis have showed the formation of halo rich in oxygen around it. Electrical measurements have confirmed the metallic nature of the impacted surface, where a conductive path can be drawn upon the insulator AlN ceramic. Laser conditions have been determined regarding to the obtention of a metallic film by this one-step process.
