- CNT and PANi were successfully combined with pineapple-polyester woven fabrics.
- All prepared composites were conducting, electroactive, and flexible.
- Pineapple fiber-containing composites produced better areal capacitance values.
- The PANi/CNT/PPWF composite gave the highest areal capacitance value of 386Â mFÂ cmâ2.
Conducting and electroactive fabrics suitable for supercapacitor electrodes were successfully prepared by combining carbon nanotubes (CNT) and polyaniline (PANi) with pineapple-polyester blended woven fabrics (PPWF) via dip-and-dry process and in situ chemical polymerization. The conductivity and capacitive behavior were studied using four-point probe technique, electrochemical impedance spectroscopy, cyclic voltammetry, and galvanostatic charge discharge experiments. PANi/CNT/PPWF composites produced higher conductivity (0.3877Â SÂ cmâ1) and areal capacitance values (386Â mFÂ cmâ2 at 1Â mAÂ cmâ2) compared to the binary composites, PANi/PPWF (0.00685Â SÂ cmâ1, 14.3Â mFÂ cmâ2), and CNT/PPWF (0.2615Â SÂ cmâ1, 8.52Â mFÂ cmâ2). Combining the high conductivity of CNT and the pseudocapacitive behavior of PANi greatly enhanced the charge storage capability of the composites. The PPWF composites also produced higher areal capacitance values compared to pure polyester composites. The incorporation of hydrophilic pineapple fibers led to lower charge transfer resistance and better electrolyte transport within the composite. Based on these characteristics, PANi/CNT/PPWF is a promising electrode material for supercapacitors.
