摘要
En 中文
Side-end and side-on liquid crystal pyrrole monomers and polymers are synthesised thanks to a mastered process. An original way of polymerisation allows to obtain 'in situ' oriented polymers. Each polymer receives either a planar or an homeotropic orientation of its mesogens. The study of static conductivities of these two materials points out an anisotropy of conductivity between the two possible orientations. This anisotropy is of opposite sign between the two materials. Another study, carried out in the dynamic mode, shows that conductivities of side-end and side-on polypyrroles have a different evolution with respect to frequency. (C) 1999 Elsevier Science S.A.
