摘要

Smart materials that can dynamically modulate incident light provide a broadprospect for the development of smart windows. However, the absence ofcapability to create smart materials with rapid transmittance switchabilityand mechanical robustness has restricted the realization of self-defensivesmart windows. Here, a solvatochromic alcogel designed by cellulose–polyacrylamidesupramolecular configuration for developing a self-defensivesmart window is reported. The alcogel with compact nano-bulge structuresexhibits reversible and rapid switching of transparency between 85% and5%, cycle time less than 8 s, and has strong mechanical robustness withelastic modulus of over 60 MPa. With this smart alcogel, the proposed selfdefensivesmart window not only shows real-time and reliable adjustment oftransparency but also outputs a strong mechanical impact resistance of up to42.8 kJ m~(?2), 10 and 12 times higher than that of a normal glass and photochromicwindow, respectively. It is believed that this study will open newopportunities for both fabrication and application of biological gels in smartwindows and intelligent devices.
