摘要

采用溶液浇铸技术，在羧甲基纤维素上掺杂不同浓度的油酸，制备了生物聚合物电解质。利用傅里叶变换红外光谱对盐与聚合物的络合作用进行了研究。在1710、2850、2920 cm-1处出现新峰。x射线衍射研究揭示了生物聚合物电解质的无定形性质。阻抗研究表明，在室温(303 K)下，当油酸含量为20%时，生物聚合物电解质的最高离子电导率σ为2.11 × 10-5 S·cm-1，符合阿伦尼乌斯行为。

The Oleic Acid Composition Effect on the Carboxymethyl Cellulose Based Biopolymer Electrolyte

Biopolymer electrolyte based on carboxymethyl cellulose has been prepared by doping with different concentration of oleic acid via solution casting technique. Fourier Transform Infrared spectroscopy was used to study the complexation between the salt and polymer. New peak was observed at 1710, 2850, 2920 cm-1. X-ray diffraction study reveals the amorphous nature of the biopolymer electrolyte. Impedance study shows the highest ionic conductivity, σ, was found to be 2.11 × 10-5 S·cm-1 at room temperature (303 K) for sample containing 20 wt.% of oleic acid and the biopolymer electrolyte obeys Arrhenius behaviour.
