报告摘要：
A bilayerstructure composed of polyvinyl alcohol composite thin film atop thickelastomer substrate was designed and prepared to achieve dynamicstrain-responsive optical properties. The transition between a transparentstate to an opaque state can be easily achieved by uni-axially stretching andreleasing the device. Also, a series of derivative mechanochromisms withcapabilities of switch “on/off” fluorescence, change fluorescent color,reveal/hide information upon mechanical stimuli are prepared. These devicesfeature virtually no changes in optical/mechanical properties after beingrepeatedly stretched and released thousands of times, promising for widespreadapplications.
