Abstract : Until now the plane texture of the cholesteric mesophase could only be affected by changing the enclosing surfaces or the temperature. This study has shown how electric fields may rapidly orient and align such mesophases. In spite of intense electric fields, remarkably stable long range molecular order persists in the mesophase of cholesteryl nonanoate. Such materials may form an interesting new class of insulators. The newly found properties make possible the further study of mesophase structure, electric dipole moments, viscoelastic properties, and the fluid dynamics of viscous materials. (Author)
