Polypyrrole (PPy) as a conducting polymer has potential
applications in electrical and electronic devices. This book
therefore aimed to produce novel "polypyrrole fibres via the
development of nanostructured conducting polypyrrole" by fibre
spinning of PPy and to investigate the formed fibres for
applications such as actuators, e-textiles, batteries, sensors and
biomedical areas. As a result polypyrrole fibres have been produced
for the first time. Subsequent work sought to improve the
properties of these first generation PPy fibres by increasing the
molecular weight, addition of carbon nanotubes (CNTs) and addition
of a supporting polymer (alginate). The use of the host polymer
also enabled a new fibre spinning method to be developed that
included an in situ polymerization process. The highest
conductivity and Young's modulus of any conducting polymer based
fibre reported to date was obtained by incorporating PPy into a CNT
yarn. In summary, a range of novel fibres PPy materials have been
developed for possible use in applications such as actuators,
sensors, artificial muscles, batteries and biomedical applications.
