The solid-state Ag / AgCl electrode was used to explore the ocean electric field. The effects of sintering technologies on the stability of electrode potential were researched. Four kinds of electrodes, which were respectively sintered to two temperatures of 380°C and 420°C by two heating methods of direct heating and phase-type heating methods, were prepared. Their surface morphologies, metallographic structures and the electrode potentials in 3.5% sodium chloride solution were analyzed to compare the stability of different sintering technologies. The results show that the electrodes sintered to 380°C by phase-type heating - insulation method have the best stability of potential, and potential difference of two electrodes is less than 0.02079mv/h.
PDLC films are very useful materials and can apply in flexible displays, intelligent switchable windows, information storage and adaptive optical devices. In this paper we focus on its color display characteristic in reflective display and firstly we fabricated PDLC films by polymerization induced phase separation method and measured its transmissivity and spectral reflection curves of the printing ink layer and PDLC covered color by X-Rite DTP41 Spectrophotometer. From the result, it demonstrates that PDLC films show different optical transmission properties in long and short wavelength.
nanoTiO2 is one of the most important inorganic pigments in many different fields. The effect of sinter and thermoprint on film-forming properties of nanoTiO2 in screen printing were studied in this paper. Compared with sintering, Thermoprint uses high temperature and pressure to make nanoparticles more tight. By scanning electron microscopy (SEM), X-ray diffraction (XRD) and Coating Adhesion Test, the better film-formation properties of thermoprint are demonstrated.
PEDOT/PSS has an excellent performance in the electronic components and ink jet print has been used widely printed electronics. But the film quality of PEDOT/PSS produced by ink jet printers can be limited by many parameters and is very difficult to evaluate accurately. In this paper, we propose uniformity and precision as the key indicators and combine image processing method in to the evaluation methods. First we analyses the characteristic and limitation of the ink jet printer, and use image processing methods to evaluate the experimental data. From the result it demonstrates this new method is feasible, and can get more detail. And it can apply in the future dedicated ink jet printer study and quality detection
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
