Smart(adaptive, responsive) polymers change their properties under an environmental effect (change in temperature, pH etc.) in a fast, reversible and nonlinear way. Investigation of these materials is a hot topic in the polymer chemistry research field, because the deeper understanding of the behaviour of such polymers is hoped to help creating many technological innovations. In case of thermoresponsive polymers usually the solubility, whereas in case of gels the degree of swelling change sharply depending on the temperature. Among others poly(N-isopropylacrylamide), poly(diethylacrylamide), polyoxazolines and some poly(poly(ethylene glycol) methacrylates) show these behaviour in water. Our research group investigates primarily the behaviour of these macromolecules and researches the potential tuning of the temperature of the transitions.
