Switchable glazing for adaptive solar control achieved by bistable hydrogels |
| 초록 |
In this study, we have modified the chemical structure of the PNIPAm based polymers, achieving hydrogels capable of programmable thermal behavior. We could prepare the multi-components copolymers having a compositional gradient by slow addition of the monomers in the reaction mixture. Prepared copolymers exhibit nearly linear transmittance change over a wide temperature range, demonstrating gradual solar control of the smart window in response to the sunlight intensity as well as temperature. Furthermore, poly(N-isopropylacrylamide)-graft-methylcellulose hydrogel (PNIPAm-g-MC) was prepared through the grafting of PNIPAm onto a MC backbone and simultaneous cross-linking of the chains. Base on the large thermal hysteresis of PNIPAm-g-MC in its volume change, programmable volume phase transition could be triggered by visible light irradiation |
