A creation of an intelligent surface - the design of a reactive surface with stimuli-sensitivity toward temperature and pH

摘要

There are many kinds of polymers which respond to environmental conditions. Such polymers vary their characteristics such as solubility and conformation with changing environmental conditions such as temperature, solvent composition, pH, ionic strength, and electric field. For example, a poly(N-isopropylacrylamide) (polyNIPAAM) aqueous solution shows a phase transition with temperature, which is known as the lower critical solution temperature (LCST).
