| Research Abstract |
The deposition of thin LiCoO_2 and hydroxyapatite layers was studied using the electrostatic spray deposition (EDS) technique. Lithium and cobalt acetate were dissolved in a mixture of 50 mol% ethanol and 50 mol% butyl carbitol for the preparation of LiCoC_2 thin films. Also, Calcium nitrate and phosphoric acid were dissolved in a mixture of 10 vol% ethanol and 90vol% butyl carbitol for the preparation of hydroxyapatite thin films. The effect of process condition such as deposition temperature, concentration of feed solution and deposition time on the surface morphology and microstructure of thin films were examined with scanning electron microscopy (SEM). For the deposited LiCoO_2 layers, various surface structure, such as reticular, fractal or fold one, was fabricated at various process conditions, while all the samples have a fractal structure for the preparation of hydroxyapatite layers. The deposited thin-film LiCoC_2 and hydroxyapatite, were amorphous or nanocrystalline at the used deposition temperature(200℃). Subsequently, the samples were heated at 700℃ for 1h or 900℃ for 2h, respectively and were studied using X-ray diffractometry(XRD). The crystal structure of samples transformed to the desired phase.
