Abstract
A method of reversible selective manifestation of different states of a functional element is disclosed. The functional element is composed of at least two compounds and is capable of alternatively assuming (a) a first state in which the two compounds interact to form a regular aggregate structure, or (b) a second state in which the two compounds do not interact, and at least one of the two compounds is in an aggregate or crystallized state. The respective conditions for attaining one of the two states can be reversibly and extremely speedily controlled, for instance, by use of a heat application device.
