Herein, inspired by the dynamic sacrificial bonds in biomaterials and the self-strengthening of skeletal muscles by physical exercise, high performance artificial muscle material is prepared by rearrangement of sacrificial coordination bonds in the polyolefin elastomer via a repetitive mechanical training process. Biomass lignin is incorporated as a green reinforcer for the construction of interfacial coordination bonds. The prepared artificial muscle material exhibits high actuation strain (>40%), high actuation stress (1.5 MPa) which can lift more than 10000 times its own weight with 30% strain, characteristics of excellent self-strengthening by mechanical training, strain-adaptive stiffening, and heat/electric programmable actuation performance. In this work, we show a facile strategyfor the fabrication of intelligent materials using easily available raw materials.</dc:description> <dc:identifier>https://archive.materialscloud.org/record/2021.29</dc:identifier> <dc:identifier>doi:10.24435/materialscloud:9a-7y</dc:identifier> <dc:identifier>mcid:2021.29</dc:identifier> <dc:identifier>oai:materialscloud.org:741</dc:identifier> <dc:language>en</dc:language> <dc:publisher>Materials Cloud</dc:publisher> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/legalcode</dc:rights> <dc:subject>artificial muscle materials</dc:subject> <dc:subject>mechanical training</dc:subject> <dc:subject>sacrificial coordination bonds</dc:subject> <dc:subject>self-strengthening</dc:subject> <dc:subject>strain-adaptive stiffening</dc:subject> <dc:subject>programmable actuation</dc:subject> <dc:subject>lignin</dc:subject> <dc:title>Biomimetic high performance artificial muscle built on sacrificial coordination network and mechanical training process</dc:title> <dc:type>Dataset</dc:type> </oai_dc:dc>
