Study on the Dynamic Behavior of Electrostatic Atomization Sprayed a Series of Liquids
Electrostatic atomization spraying has been considered as a promising method to fabricate porous TiO2 thin film electrodes of dye-sensitized solar cells.In the present study, electrostatic atomization behavior of several test liquids having much higher viscosities (1400 mPa·s) than have previously been studied was investigated by spraying at a series of applied voltages and flow rates.The results showed that to obtain stable cone-jet mode spraying and hence gain better monodispersity of droplets, electrical conductivity, viscosity and surface tension of the liquid are important controlling factors.The stable cone-jet mode could easily be established for liquids having shear viscosities in the range from 80 to 1400 mPa·s and surface tensions below 65 mNm-1.In contrast, methylcellulose aqueous solutions with shear viscosities ranging from 10 to 540 mPa·s and moderate surface tensions (50-56 mNm-1) generated more complicated spraying modes.
