Polymers that switch properties with temperature

What is it about?
Thermoresponsive polymer brushes have been grown on micropatterned substrates and an atomic force microscope has been used to measure the brush height and adhesion to the AFM tip. The polymer brushes undergo reversible phase changes in water at 32 °C (the polymer’s lower critical solution temperature), with polymer properties switching from hydrophilic (water-liking) to hydrophobic (water-hating).
Why is it important?
Tailoring properties of materials according to temperature, and other stimuli such as pH, is an important step in making switchable patterned surfaces that could form new classes of microdevices.
