摘要：

Vinylidene fluoride/trifluoroethylene copolymer thin films cast from dilute cyclohexan6ne solution on vacuum-evaporated Pt, Al, Cu, and Au were annealed at 420K for 1 h. Transmission electron microscopic observation revealed that the high-temperature phase (HP) of the copolymers was frozen even at room temperature with molecular chains normal to the substrate after the annealing. The maximum lattice mismatch was 3.3% between the (001) plane of the HP of the copolymers and the {111} or {110} plane of the Pt crystals. Coulomb's interaction between the copolymer molecules and metallic atoms is suggested to have an important role in causing such phenomena.
