摘要：

The electrical conductivity of nickel-poly(acrylate divinylbenzene) has been studied over a wide range of temperatures. Poly(acrylic acid-divinylbenzene) was doped with nickel acetate to prepare samples containing 5.35, 9.73 and 25.0% (w/w) nickel and current-voltage relationship was studied as a function of concentration and temperature. There is a linear variation of electric current with applied voltage. The slopes of In (I) vs In (V) plots being equal to one which suggests the ohmic behaviour of charge carriers. The conductivity has a strong concentration and temperature dependence and is non-monotonic. The conductivity is considered to be due to thermal hopping motion of localized charge carriers which are believed to be polarons.
