Elaboration and characterization of polypyrrole-carbon composites

open access: yes, 1992
Polypyrrole-carbon composites were prepared by electrochemical deposition of polypyrrole on anodes of carbon fibres or carbon fabric. The corresponding voltamperograms are analyzed and the evolution of the electrical conductivity of such composites with ...

Artificial Muscles from Hybrid Carbon Nanotube-Polypyrrole-Coated Twisted and Coiled Yarns

open access: yes, 2020
Electrochemically or electrothermally driven twisted/coiled carbon nanotube (CNT) yarn actuators are interesting artificial muscles for wearables as they can sustain high stress.

Spontaneous coating of carbon nanotubes with an ultrathin polypyrrole layer

open access: yes, 2007
A novel protocol for precisely coating individual multiwall carbon nanotubes (MWCNTs) with an ultrathin layer of polypyrrole was developed. The nanocoated MWCNTs were successfully prepared by in situ chemical deposition of polypyrrole in an aqueous ...

Morphologies Tuning of Polypyrrole and Thermoelectric Properties of Polypyrrole Nanowire/Graphene Composites [PDF]

open access: yesPolymers, 2018
Polypyrrole (PPy) with different morphologies (e.g., particles, nanotubes, and nanowires) were successfully prepared by adding or without adding different kinds of surfactants through a chemical oxidative polymerization method, respectively. The results show that the morphologies of PPy can be effectively controlled and have a significantly effects on ...
