“…The use of PANI-CNT composite as an electrode in a hybrid capacitor has been suggested first by Frackowiak and Beguin [106]. In the past few years, many attempts have been made to improve the capacitance of PANI-CNT-based devices [107][108][109][110][111][112][113][114]. The details of the cell construction with the experimental values of capacitance obtained in these studies are presented in Table 1.…”

Abstract:The key developments in polyaniline-carbon nanotube (PANI-CNT) composites are reviewed. Apart from in situ chemical polymerization and electrochemical deposition, a number of interesting approaches including the use of aniline functionalized CNTs and ultrasound/microwave/γ-radiation initiated polymerization have been used in the preparation of composites. The structure and properties of these composites have been investigated by a variety of techniques including absorption, infrared (IR), Raman, X-ray photoelectron spectroscopy methods, scanning electron and scanning probe microscopy techniques, cyclic voltammetry, and thermogravimetry. The experimental results indicate favorable interaction between PANI and CNTs. The CNT content in these composites controls their conductive, mechanical, and thermal properties. The most interesting characteristic is their easy dispersibility in aqueous solution. The performance evaluation studies of PANI-CNT composites in a number of applications including supercapacitors, fuel cells, sensors, and actuators are highlighted.

“…The SWNT (or multi walled nanotubes) can provide an effective conduit for charge delivery. 23,29,30 This ability is beneficial in applications that require electrochemical switching of the ICPs such as with high-strength artificial muscles. 22 Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonicacid) (PEDOT:PSS) can be made highly conductive, is environmentally stable and commercially available.…”

In order to exploit the inherent properties of carbon nanotubes (CNT) in any polymer composite, systematic control of carbon nanotube loading and protocols that mitigate against CNT bundling are required. If such composites are to be rendered in fiber form via wet-spinning, then CNT bundling during the coagulation process must also be avoided. Here we have achieved this by utilizing highly exfoliated single walled carbon nanotubes (SWNT) and poly(3,4-ethylenedioxythiophene):poly(styrenesulfonicacid) (PEDOT:PSS) to obtain wet-spinnable composite formulations at various nanotube volume fractions (V f ). The addition of only 0.02 V f of aggregate-free and individually dispersed SWNT resulted in a significant enhancement of modulus, tensile strength, electrical conductivity and two cell electrode specific capacitance of PEDOT:PSS-SWNT composite fibers to 5.2 GPa, 200 MPa, 450 S cm −1 and 59 F g −1 by the rate of dY/dV f = 89 GPa, dσ/dV f = 3.2 GPa, dS/dV f = 13300 S cm −1 and 6 folds, respectively.

Objective: To study the interactive influence of implanted nano platinum black electrodes (as compared with pure platinum electrodes) on rabbit orbicularis oculi muscle morphology and function.Methods: The influence of the two types of electrode on the orbicularis oculi muscle was monitored in a rabbit model of facial paralysis. Biological electric current and exciting current were administered to biological tissue, and morphological and functional changes were identified. Changes in orbicularis oculi muscle contraction, electrode configuration and performance associated with long-term electrical stimulation were observed over 28 days of implantation.Results: The nano platinum black electrode was superior to the pure platinum electrode in the following aspects: morphology and functionality, electrical excitation function of the orbicularis oculi muscle (as assessed by electromyography), muscle contraction function and biological tissue changes. Furthermore, the nano platinum black electrode features had good stability.Conclusion: Microelectrode surface modification with nano platinum black can effectively increase the microelectrode surface area and improve electrode performance, and is associated with good tissue compatibility.
