碩士 === 國立臺灣科技大學 === 材料科學與工程系 === 101 === This study targeted for the light-curing resin blended with nanoparticles. Nanoparticles are used as conductive carbon black, model Vulcan XC-72. The object of study for the composites after blend of stability and dispersibility of colloidal. To know the trend and phenomenon, and then go with the other physical properties of the presumption of optimal formulations. The main research projects used for Dispersion Analyser LUMiSizer) of LUM(Labor-, Umweltdiagnistik & Medizintechnik, this instrument can be used for testing particle size distribution, stability, dispersibility and shelf time, etc. Based on the time and space in two different ways to detect, referred to as STEP (Space and Time resolved Extinction Profiles) technology. Mainly in the penetration and absorption of the light source by moving particles for mapping. The slope, light transmittance and time of the figure shown, can be used to analyze many items. We use ASTM D3359 and CNS 10757 to detect adhesion stability and pencil hardness, mainly to investigate the material properties when composite colloidal add the dispersant and changing other factors. The dispersion system’s stable and unstable are investigated in many studies. The research methods such as naked eye, electrophoresis, microscopes, acoustic and electrical conductivity measurements, etc. Which contains many of the centrifugal environment for experiments. S.T.E.P. technology used in this study. In line with centrifugation and near infrared, can greatly reduce experimental time, and observe the sample from the initial state to the end state of a particle migration path to achieve the purpose of saving time and objective.
