Thermo-responsive polymers that exhibit phase transition in response to changes in the external temperature can be used as material for smart window because they can control solar light transmission depending on the external temperature. The thermos-responsive polymer solution does not heat up sufficiently to induce a phase change even under intense sunlight. Therefore, nanofillers that can convert the photoenergy of sunlight into thermal energy need to be added, which cause the thermos-responsive solution to reach an opaque state owing to the increased temperature by solar light. Thermo-responsive polymer nanocomposites based on the PVME and nanofillers with photothermal conversion property were prepared by simple solution mixing, and photothermal efficiencies of the nanofillers were investigated. And the transparent-opaque transition behaviors during the repeated heating and cooling processes of the thermo-responsive polymer nanocomposites were discussed. |
