Abstract

We have investigated a new process for the fabrication of nanocomposite cups by electrospraying blended polymer-sol-gel solutions followed by calcination. Due to the low viscosity and high surface tension of the blended polymer-sol-gel solutions, the electrostatically extruded continuous liquid jet from the spray source became tiny droplets with diameters of less than 1 νm. These droplets dried in transit and were collected at the counter electrode. To eliminate polymers, as well as cross-link sol-gel material, they were calcined at 850 °C for 3 h. We also investigated a probable method to control the morphology of the nanocups by changing the ionic concentration of the polymer solution. This is a simple and efficient approach for producing nanocomposite cups, which cannot be made by the aggregation method. These nanocomposite cups may find applications in drug delivery and filtration media.
