The deformation can be explained in terms of differences in thermal expansion depending on the average molecular orientation of the mesogenic centers of the monomeric units. The thermal expansion of the anisotropic polymers has been characterized as a function of their molecular structure and the polymerization conditions. As a reference, films with an in-plane 90° twist have also been studied and compared with the splayed, out-of-plane molecular rotation. The twisted films show a complex macroscopic deformation owing to the formation of saddle-like geometries, whereas the deformation of the splayed structured is smooth and well controlled. The deformation behavior is anticipated to be of relevance for polymer-based microelectromechanical system (MEMS) technology. REFERENCES 1 G. Tresset, S.
