Abstract
Composites consisting of camphor sulfonic acid (CSA)-doped poly(o-toluidine) (POT) and insulating poly(methyl methacrylate) (PMMA) show percolation behavior and the value of percolation threshold to be 4 wt% of conducting CSA-doped POT. The composite was considerably transparent, e.g., the transmittance of the composite (∼15um) with 4% of CSA-doped POT and 96% of PMMA was about 70% at 540nm. Conductivity at the percolation threshold point is attributed to the interconnected network, which was revealed by scanning tunneling micrographs. Thermogravimetric analysis demonstrates four step decomposition and phase separated morphology of CSA-doped POT is found to be thermodynamically stable up to 250°C. This was supported by mass spectra simultaneously recorded in thermal analysis.
