The PEDOT composites in PMMA matrix have been prepared by thermal polymerization of 2,5-dibromo-3,4-ethylenedioxythiophene (DBEDOT).The composite film was obtained from electrospinning the solution mixture of 3:1, 4:1, 5:1 weight ratios of DBEDOT:PMMA at the concentration of 0.18 g/mL PMMA.The polymerization of DBEDOT embedded in the PMMA matrix was induced at 80 ℃.The result showed that the sample prepared at weight ratio 4:1 of DBEDOT:PMMA incubated for 72 h gave the lowest surface electrical resistance.The values of electrical resistance of the PEDOT composite film were found to decrease upon storage, possibly due to slow polymerization of the remaining monomer or slow reorganization of the polymer structure in doped state.The composite film was stable and remained highly conductive up to at least 2 months.
