| 中文摘要 | we here present a versatile process for the preparation of maghemite/polyaniline (gamma-fe2o3/ pan) nanocomposite films with macroscopic processibility, electrical conductivity, and magnetic susceptibility. the gamma-fe2o3 nanoparticles are coated and the pan chains are doped by anionic surfactants of omega-methoxypoly(ethylene glycol) phosphate (peopa), 4-dodecylbenzenesulfonic acid (dbsa), and 10-camphorsulfonic acid (csa). both the coated gamma-fe2o3 and the doped pan are soluble in common organic solvents, and casting of the homogeneous solutions gives free-standing nanocomposite films with gamma-fe2o3 contents up to similar to 50 wt %. the morphology of the gamma-fe2o3 nanoparticles are characterized by transmission electron microscopy, uv-vis spectroscopy, and x-ray diffractometry. the gamma-fe2o3/pan films prepared from chloroform/m-cresol solutions of dbsa-coated gamma-fe2o3 and csa-doped pan are conductive (sigma = 82-237 s/cm) and superpapamagnetic, exhibiting no hysteresis at room temperature. the zero-field-cooled magnetization experiment reveals that the nanocomposite containing 20.8 wt % gamma-fe2o3 has a blocking temperature (t-b) in the temperature region of 63-83 k. |
