Photoinduced stress\/strain originates from the changes in mechanical properties after light irradiation. However, the correlation between the photoinduced mechanical performance and in\u2010use conditions such as stress\/strain states and polymer network properties (such as effective crosslink density and dangling chain density) remains unexplored for practical applications. Here, isometric photo\u2010induced stress or isotonic strain is investigated at different operating strains or stresses, respectively, on LCEs with polymer network variations, produced by different amounts of solvent during polymerization. As the solvent volume increases, the moduli and photoinduced stresses decrease. However, the photo\u2010induced strain, fracture strain, fracture stress, and viscosity increase. The optical response performance initially increases with the operating strain\/stress, peaks at a higher actuation strain\/stress, and then, decreases depending on the polymer network. The maximum work densities, which also depend on the operating stress, are in the range of \u2248200\u2013300 kJm<jats:sup>\u22123<\/jats:sup>. These findings, highlighting the significant variations in the mechanical performance with the operating stress\/strain ranges and amount of solvent used in the synthesis, are critical for designing LCE\u2010based mechanical devices.<\/jats:p>","DOI":"10.1002\/marc.202300709","type":"journal-article","created":{"date-parts":[[2024,4,5]],"date-time":"2024-04-05T08:15:34Z","timestamp":1712304934000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Effects of Operating Mechanical Conditions and Polymer Networks of Nematic Elastomers on Photo\u2010Induced Mechanical Performances"],"prefix":"10.1002","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2185-2504","authenticated-orcid":false,"given":"Takuya","family":"Ohzono","sequence":"first","affiliation":[{"name":"Research Institute for Advanced Electronics and Photonics National Institute of Advanced Industrial Science and Technology (AIST)  1\u20101\u20101 Higashi Tsukuba 305\u20138565 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0057-1474","authenticated-orcid":false,"given":"Emiko","family":"Koyama","sequence":"additional","affiliation":[{"name":"Research Institute for Advanced Electronics and Photonics National Institute of Advanced Industrial Science and Technology (AIST)  1\u20101\u20101 Higashi Tsukuba 305\u20138565 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,4,13]]},"reference":[{"key":"e_1_2_9_1_1","volume-title":"Liquid Crystal Elastomers","author":"Warner M.","year":"2007"},{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/oso\/9780198520245.001.0001"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1051\/jp2:1994116"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevE.66.061710"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.103.037802"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.63.1082"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1126\/sciadv.abe9495"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/admi.202100672"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-021-27013-0"},{"key":"e_1_2_9_10_1","first-page":"1","volume":"246","author":"Saed M.
