Applied Energy, 2009Co-Authors: Weilong Wang, Xiaoxi Yang, Yutang Fang, Jing DingAbstract:This work mainly involved the preparation and characterization of form-stable polyethylene glycol (PEG)/Silicon Dioxide (SiO2) composite as a novel solid-liquid phase change material (PCM). In this study, the polyethylene glycol/Silicon Dioxide composites as form-stable, solid-liquid phase change material (PCM) was prepared. In this new material, the polyethylene glycol acts as the latent heat storage material and Silicon Dioxide serves as the supporting material, which provides structural strength and prevents the leakage of the melted polyethylene glycol. Results indicated that the composite remained solid when the weight percentage of Silicon Dioxide was higher than 15%. Moreover, the polyethylene glycol was observed to disperse into the network of the solid Silicon Dioxide by investigation of the structure of the composite PCMs using a scanning electronic microscope (SEM). The properties of the porous materials and phase change materials were characterized using Fourier transformation infrared spectroscope (FTIR). The transition process was observed using polarizing optical microscope (POM) and dynamic thermo mechanic analysis (DMA). The melting temperatures and latent heats of the form-stable PEG/SiO2 composite PCMs were determined using differential scanning calorimeter (DSC).

deposition of Silicon Dioxide films with a non equilibrium atmospheric pressure plasma jet
Plasma Sources Science and Technology, 2001Co-Authors: S E Babayan, J Y Jeong, Gary S Selwyn, A Schutze, M Moravej, Robert F HicksAbstract:Silicon Dioxide films were grown using an atmospheric-pressure plasma jet that was produced by flowing oxygen and helium between two coaxial metal electrodes that were driven by 13.56 MHz radio frequency power. The plasma exiting from between the electrodes was mixed with tetraethoxysilane (TEOS), and directed onto a Silicon substrate held at 115-350 °C. Silicon Dioxide films were deposited at rates ranging from 20±2 to 300±25 nm min-1. The deposition rate increased with decreasing temperature and increasing TEOS pressure, oxygen pressure and RF power. For the latter two variables, the rate increased as follows: Rd∝P0.3O2(RF)1.4. Films grown at 115 °C were porous and contained adsorbed hydroxyl groups, whereas films grown at 350 °C were smooth, dense and free of impurities. These results suggest that the mechanism in the atmospheric pressure plasma is the same as that in low-pressure plasmas.

deposition of Silicon Dioxide films with an atmospheric pressure plasma jet
Plasma Sources Science and Technology, 1998Co-Authors: S E Babayan, J Y Jeong, Jaeyoung Park, Gary S Selwyn, Robert F HicksAbstract:A plasma jet has been developed which deposits silica films at up to at 760 Torr and 115 to C. The jet operates by feeding oxygen and helium gas between two coaxial electrodes that are driven by a 13.56 MHz radio frequency source at 40 to 500 W. Tetraethoxysilane is mixed with the effluent of the plasma jet and directed onto a substrate located 1.7 cm downstream. The properties of the silica films, as determined by infrared spectroscopy and capacitance measurements, are comparable to those of thermally grown Silicon Dioxide films at C.
