Carbon Black‐Filled Nitrile Rubber Composite as a Flexible Electrode for Electrochemical Synthesis of Supercapacitive Polyaniline

Abstract

This work reports the development of carbon black‐filled flexible conductive composite as an effective electrode material to substitute of graphite for electrochemical synthesis of supercapacitive polyaniline (PAni). Elastomeric composites of acrylonitrile butadiene copolymer (NBR) as a matrix with different types of carbon black fillers viz., N660, N330 and XC72 (VULCAN® XC‐72) were prepared through melt mixing method. Among these composites, NBR‐XC72 exhibited the highest bulk electrical conductivity and charge carrier concentration coupled with good mechanical properties. Generally, high level of conductivity is required for a material to be used as an electrode in electrochemical synthesis. The NBR‐XC72 composite with 90 phr black loading can be used as an effective material for electrode electrochemical synthesis of PAni from aniline. Two different PAni samples were prepared using both graphite electrode (PAni‐G) as well as flexible composite electrode (PAni‐R). The specific capacitance of PAni‐G was found to be around 380 Fg−1 in comparison to 213 Fg−1 for PAni‐R at the discharge rate of 1 Ag−1. The retention of specific capacitance of PAni‐R was found to be 90% notably better than that of Pani‐G (81%) after 1,000 cycles of charge–discharge (CD) process. POLYM.

Study of mechanical and thermal behavior of alkali modified groundnut shell powder reinforced ABS composites

“…Composites materials are essential in many forms for the survival of human life, and they may be structural, [1][2][3][4] functional, [5,6] or biomaterial. [7] However, the fabrication of synthetic fibers for polymer composite manufacturing leads to the generation of immense waste and energy consumption.…”

A review on the alternative of indium tin oxide coated glass substrate in flexible and bendable organic optoelectronic device

“…It can be broadly classified as intrinsically conducting polymers (ICPs) and extrinsically conducting polymers (ECPs), as shown in Figure 4 and compared their properties in Table S2. ICPs conduct the electricity due to the conjugation of their backbone, and ECPs owe their conductivity due to the presence of externally added conductive filler 84,85 …”

“…ICPs conduct the electricity due to the conjugation of their backbone, and ECPs owe their conductivity due to the presence of externally added conductive filler. 84,85 The electrical properties of an insulator polymer can be modified by the addition of conducting fillers, while other intrinsic properties, such as optical transparency and flexibility, will remain unaltered. 86 Nanosized conductive fillers (CNTs, graphene, metal nanoparticles, etc.)…”

“…[1][2][3] In the rubber processing process, carbon black (CB) as the most widely used and the largest use of fillers, greatly enhanced the comprehensive physical and mechanical properties of rubber products. [4][5][6][7][8] At the same time, the heavy use of CB caused environmental pollution and the energy consumption of its production process was enormous. 9 Besides, CB from the oil industry was also contrary to the concept of green and sustainable consumption.…”
