The obtained polyurethane CPPU\u201050 exhibits good photoinduced bending, thermal responsive shape memory effect, humidity triggered deflections and self\u2010healing properties. Furthermore, an actuator combining light and thermal stimuli is created and the self\u2010healing CPPU\u201050 film can withstand the object of 1800 times without tearing. This work can pave a way for further development of long\u2010lived multi\u2010stimuli\u2010responsive actuating devices and intelligent materials.<\/jats:p>","DOI":"10.1002\/marc.202300281","type":"journal-article","created":{"date-parts":[[2023,8,5]],"date-time":"2023-08-05T23:10:40Z","timestamp":1691277040000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Synthesis of Self\u2010healing and Light\u2010, Thermal\u2010, and Humidity\u2010induced Deformative Polyurethane Actuator"],"prefix":"10.1002","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1813-2995","authenticated-orcid":false,"given":"Chen","family":"Dong","sequence":"first","affiliation":[{"name":"Key Laboratory of Synthetic and Nature Molecule of Ministry of Education Shaanxi Key Laboratory for Carbon Neutral Technology Department of Chemistry &amp; Materials Science Northwest University  Xi'an 710127 P.
