Electrorheological Fluids Based on Titania Particles Coated with Silica and Their Application in Smart Windows

Keywords： Electrorheological fluid

The electrorheological (ER) fluids are colloidal suspension of highly polarizable particles in a non-conducting solvent. Chains ofsubmicron-sized particles formed along an applied DC electric field by the so-called electrorheological effect. According to theobvious change of transmittance of the ER fluids in a DC electric field when the polarized particles arranged along the field,the model of smart window was proposed by sandwiching the ER fluids based on titania particles coated with silica between apair of In-Sn oxide (ITO) coated glasses. The solar transmittance change as much as 48.0% was obtained with the wavelengthof 500 nm at the maximum on applying and removing the electric field of 500 V/mm.
