摘要：

The potential ability of photochromic hydrogel as smart response material is determined by its coloration and fading speed. However, it is still a huge challenge to improve both the coloration and fading speed simultaneously. This paper presents the successful development of robust hydrogels with fast photoresponse and waterdriven ultra-fast fading speed through the implementation of a dual-network preparation strategy. In the dualnetwork hydrogel, sodium tungstate contributed to its discoloration and crosslink. The obtained hydrogel exhibited fast photochromic response within 20 s under visib...
