Abstract
Abstract Ethyl-acetyl cellulose ((E-A)C)/dichloroacetic acid (DCA) cholesteric liquid crystalline solution could form a homogeneous planar texture which exhibits a vivid colour. In the planar texture, there were two kinds of domains which had a homogeneous structure and a periodically changed structure, respectively. The increase of both concentration and temperature could cause a change of the wavelength of selective reflection arising from the cholesteric phase to shorter wavelength. The cholesteric phase had different colours when the incident angle and the reflecting angle were changed. The colour of the (E-A)C/DCA cholesteric phase had a higher thermal stability than that of small organic molecule cholesteric phase.
