Abstract
An artificial flower apparatus has a stem with a plurality of petals attached to the stem with each petal having a polymer substrate and at least one petal having a thermochromatic liquid crystal mixture sandwiched between a transparent polymer substrate and an absorbing background material which thermochromatic liquid crystal mixture changes color responsive to changes in temperature thereof so that portions of the artificial flower changes color responsive to changes in temperature. The thermochromatic liquid crystal mixture may be microencapsulated and the flower petals may use different thermochromatic liquid crystal mixtures in order to provide a variety of colors among the artificial flower petals.
