摘要:
AbstractThe polymer composites were prepared by reticulate doping of polystyrene and poly(γ‐methyl‐L‐glutamate)(PMGA) with 1‐methyl‐3‐alkylimidazolium‐7,7,8,8‐tetracyano‐p‐quinodimethane simple salts I and complex salts II. The electric conductivity strongly depends on the chemical structure of the donor, on the stoichiometry and concentration of the radical salts, on the type of the polymer, and on the preparation conditions of the films. A high conductivity, even higher than that of pure radical salts measured in pressed pellets, was obtained in the PMGA doped films, and is most probably due to the α‐helical conformation. This high order conformation of molecules forces microcrystals of charge transfer salts to grow in long hair‐like shapes distributed regularly in the
