Multifunctional Wearable Electronic Textiles Using Cotton Fibers with Polypyrrole and Carbon Nanotubes

Abstract

Multifunctional wearable electronic textiles based on interfacial polymerization of polypyrrole on carbon nanotubes/cotton fibers offer advantages of simple and low-cost materials that incorporate bactericidal, good electrochemical performance, and electrical heating properties. The high conductivity of doped polypyrrole/CNT composite provides textiles that reaches temperature on order of 70 °C with field of 5 V/cm, superior electrochemical performance applied as electrodes of supercapacitor prototypes, reaching capacitance in order of 30 F g and strong bactericidal activity against Staphylococcus aureus. The combination of these properties can be explored in smart devices for heat and microbial treatment on different parts of body, with incorporated storage of energy on textiles.

Converting Commercial Sewing Threads into High‐Performance and Flexible/Wearable Fiber‐Shaped Supercapacitors via Facile Vapor Deposition Polymerization

“…Carbon materials, metal oxides, metals and conducting polymers are common active materials. Among these materials, conductive polymers stand out because of their excellent flexibility, stability, low cost, and lightweight . So conductive polymer could also modify the surface of insulated threads.…”

Interfacial Phenomena of Advanced Composite Materials toward Wearable Platforms for Biological and Environmental Monitoring Sensors, Armor, and Soft Robotics

“…Although, more work needs to be done in order to fully understand the impact that the liquid metal/polymer interface has on the performance of wearable composites. Additionally, it is recognized that in order for liquid metal/polymer composites to be used all of the electronic components involved in the use of these type devices must also be developed as seen in works by Cao et al, Hu et al, Lima et al However, a complete summary of these works is out of the scope of this review.…”

Wearable supercapacitors based on graphene nanoplatelets/carbon nanotubes/polypyrrole composites on cotton yarns electrodes

“…In consequence, it has been observed an increasing demand for lightweight and flexible devices characterized by high conductivity level, thermal stability and negligible degradation under repeated use [9]. One of the most important applications for wearable devices refers to the development of flexible storage devices (flexible supercapacitors) [10] with characteristic high-power density, long cycling life and fast charge-discharge rate [1,2,[11][12][13].…”

“…Graphene (a very promising EDLC system) is a honeycomb lattice of sp 2 -hybridized carbon atoms that offers high surface area, high thermal and electrical conductivity that can be combined with different materials [1,27], providing core-shell structures (with pseudocapacitors, as an example) for different devices [1,12]. As an alternative, carbon nanotubes represent other important class of materials for use as EDLC supports, with advantages relative to their simple functionalization [13]. In terms of candidates for use as pseudocapacitors, polypyrrole has been considered an important material for flexible supercapacitors due to its high conductivity and chemical stability provided by chemically synthesized polymeric chains on flexible substrates [11,13,26,[28][29][30].…”
