LCEF were prepared via hydrosilation of the elastomer PMHS and liquid crystal (LC) MBB using a mixture of 11UB and vinyl-terminated PDMS as crosslinks. During wet spinning, a heated oil bath was used to initiate the first thermal crosslinking step to achieve fiber shape stability. Fibers were then drawn with a ratio of max. 2.3. Shear stress during this process was used to align the LC, generating an anisotropic state. After drawing, a second thermal crosslinking step was applied to fixate LC orientation along the fiber axis. This orientation is required to achieve contractile behavior of the LCEF after surpassing nematic-isotropic transition temperature (TNI). At this temperature, LC are enabled to reorientate/ realign, aiming for a state of maximum entropy or perfect isotropy. The rotation of the LC is transferred onto the elastomeric backbone, in which polymer chains will therefore lose their stretched state, resulting in a macroscopic contraction of the fiber. The as spun LCEF were characterized regarding mechanical properties, contraction, and mass-specific power and compared to LCE-films, shape-memory polymers (SMP), SMP-fibers, as well as human muscle. Results show great potential of these LCE fibers for application in medicine and soft robotics.
