采用化学气相聚合法制备了聚-3,4-乙烯二氧噻吩(PEDOT)/还原氧化石墨烯(RGO)复合薄膜。首先用旋涂法制备氧化剂/氧化石墨烯(GO)薄膜,然后将薄膜置于3,4-乙烯二氧噻吩(EDOT)气相聚合装置中,形成 PEDOT/GO 复合薄膜。将获得的 PE-DOT/GO 复合薄膜用葡萄糖还原剂进行处理,获得PEDOT/RGO 复合薄膜。导电性测试表明,GO 被还原后复合薄膜的电导率为35.3 S/cm,明显高于 PE-DOT/GO(14.6 S/cm)和纯PEDOT(17.3 S/cm)薄膜的电导率。电化学特性研究表明,RGO 的加入使得PEDOT/RGO 导电聚合物复合纳米材料具有优良的电化学特性及稳定性,薄膜的比电容为176.7 F/g。循环测试800次后,比容量保持率为84%,具有良好的电化学稳定性。这种化学气相聚合制备的聚合物复合纳米薄膜在超级电容器及导电材料领域有着很好的应用前景。

A chemical vapor-phase polymerization (VPP)method was employed to prepare conducting composite poly-3,4-ethylenedioxythiophene (PEDOT)/reduced graphene oxide (RGO)film.The samples to be covered with PEDOT are initially coated with a thin layer of oxidant/GO,and this modifying films was transferred to a VPP chamber containing 3,4-ethylenedioxythiophene monomer gas for chemical polymerization.The latter formed PEDOT/GO film was then treated by glucose and highly conductive PEDOT/RGO films was obtained. The conducive results showed that PEDOT/RGO films exhibited conductivity ca.35.3 S/cm,which higher than pure PEDOT (17.3 S/cm)and PEDOT/GO (14.6 S/cm)films.The PEDOT/RGO films showed specific capacitance ca.176.7 F/g and kept 84% initial capacitance after 800 cycles,indicating excellent specific capaci-tance and cycling stability performance.This VPP PEDOT nanocomposites show promising application in su-percapacitor and conducting materials.
