摘要
用电导率的方法测出了氧化栲胶溶液的临界胶束浓度。结果表明,氧化栲胶溶液具有离子型高分子溶液的特征。测定了不同浓度的氧化栲胶溶液在293K~343K温度范围内的电导率,讨论了其电导率在293K~343K温度范围内服从VTF方程。利用电导率与温度的关系,估算了氧化栲胶溶液的电导活化能。
This paper determines the electrical conductivity of oxidized tannin extract solution with the electric conductivity, he results of which show that the oxidized tannin extract solution possesses the features of the ionic polymer solution, determines the electric conductivities of the oxidized tannin extract solution with different contractions in the temperature scope from 293 K to 343 K, discusses on that the electric conductivities submit to VTF Equation in the temperature scope from 293 K to 343 K, and by using the relationship between the electric conductivity and the temperature, estimates the conductive activation energy of the Oxidized Tannin Extract Solution.
