When crosslinking was introduced, the actuation stresses were proportionally higher and plateaued above 60 °C. The residual stresses were found to be 4.9 MPa, 5.9 MPa, and 6.8 MPa, as the f values increased from 2.125, 2.25, to 2.5, respectively. It should be noted that in the f=2.5 sample TMPMP was used instead of TEMPIC since the TEMPIC polymer was too brittle to be strained to 100%. As such, we believe the plateaued stress is held by the covalent network.
