Responsive properties Clausole campione

Responsive properties. How does change of conformation at molecular scale induce change of macroscopic properties (in solutions or at interfaces)? Which stimuli? Temperature, pH, salt, light, electric or magnetic field… Which polymers? How to play with weak interactions? Dynamic bonds. Reversibility. Intermolecular interactions with weak energy (hydrogen bond, electrostatic, hydrophobic). Responsive polymers. Good/Bad solvent. LCST/UCST. Polyelectrolyte, counterions, osmotic pressure.
