In the coaxial cable space charge measurement system based on Pulsed Electro-Acoustic (PEA) method, the coupled mode of pulse is extremely important. The space charge measurement signal has a direct relationship with the coupled pulse. In this paper, based on the method that the pulse is injected into cable from outer semi-conducting layer, the space charge waveform of 10 kV cable has been measured...
In this study, we prepared nano-TiO2 fiber by elelcrospinning, and then the precursor solution was added to an appropriate amount of hydrochloric acid hydrolysis. The purpose of this work is to prepare a large number of nano-fibers using electrospinning method. It's difficult to fracture the fiber through heat treatment. We used some special technique and we succeed to obtain nanofibers. The same...
In this work, we studied the property of pure conjugated polymers P3HT and P3HT blend with PCBM films and fibers that prepared by spin coating and electrospinning. The purpose of this work is to study the technology and application of electrospinning using low molecular weight conductive polymer and didn't add salts to solution. Part I: Preparation the conductive polymer solution that dissolved in...
The spin-coating process was adopted in the fabrication of capacitors on flexible substrates. High dielectric constant materials were mixed with resins to increase dielectric constant of capacitors by a trip-roller. The effect of added content of high dielectric constant materials on the dielectric properties were studied in this work. In this study, high dielectric ceramic powder and aluminum powder...
The objective of this paper is focused on the hygroscopic swelling effect on polymeric material used in electronic package and thermo-hygro-structure coupled design and reliability analysis for finger printer package. For moisture absorption/desorption analysis, the ambient environment for temperature and humidity are set to be 60degC60%RH, 85degC60%RH and 85degC85%RH, respectively. The transient...
