Stimuli-responsive polymers upon changes in temperature, pressure and so on, have attracted attentions to achieve devices that respond on environmental changes. Among the stimuli-responsive polymers, poly(N-isopropylacrylamide) has been used for a range of applications. PNIPAm has unique phase transition behavior in water; at higher temperature than lower critical solution temperature, the polymer rapidly shrinks and becomes hydrophobic. We demonstrate photocrosslinkable bicomponent system to fabricate PNIPAm film between light-reflective metals, which can resonate the light and therefore, filtrate specific wavelength range. We found that the thickness of the PNIPAm film was varied in water, and the color of the device also varies in a wide range of wavelength. Finally, we demonstrate its photopatternability and applicability as a smart thermometer to precisely visualize surface temperature. |
