Developing conducting polymers to be utilized within the swiftly advancing electronic usage and medical application requires a detailed synthetic approach in addition to a fine engineering procedure. These polymers should be able to offer a sturdy yet processable property which makes them capable of being used in electron transfer devices and vital signaling devices. Nanocomposites made from heat resistant soluble conductive copolymers enhanced with functionalized CNT dopants, which show high conductivity and rapid oxidation reaction with desired biocompatibility, are a promising candidate. This article consists of two stages to obtain this aspired product; the first stage struggles to develop a synthetic procedure for an ideal pyrrole/indole copolymer (PPy-co-PIn) and the second stage demonstrates its nanocomposite preparation with carboxy acid modified CNT (PPy-co-PIn@CNT). In fact, primarily various routes for the synthesis of PPy-co-PIn using emulsion polymerization and solution polymerization with diverse solution ratios and three different oxidizing initiators i.e. ammonium persulfate (APS), anhydrous iron (III) chloride (FeCl3), and benzoyl peroxide (BPO) were explored and their structure was further studied by FTIR, NMR, EDX, UV–Vis, XRD, and SEM techniques. Moreover, the effect of either synthetic strategy on processability, heat property, conductivity and anticorrosion property of the copolymer was measured until the finest copolymer was recognized. Latterly from this copolymer, PPy-coPIn@CNT nanocomposite was synthesized in three feed ratios of 0.025, 0.050 and 0.075 percent of modified CNT to the selected copolymer in order to enhance its corrosion resistance and related electric property performance. The antioxidant ability, antibacterial property and thermal resistance of the nanocomposite were further studied. Preliminary studies revealed the production of conductive nanocomposite with good thermal property and relatively good antibacterial inhi
