Electrodeposition and magnetic properties of polypyrrole–Fe nanocomposites

Morphochemical evolution during ageing of pyrolysed Mn/polypyrrole nanocomposite oxygen reduction electrocatalysts: A study based on quasi-in situ photoelectron spectromicroscopy

“…Starting from a solution containing pyrrole and a metal salt, the co-electrodeposition of PPy and metal nanoparticles has been proved to be possible for gold [44], nickel [45] and iron [46]. Galvanostatic anodic electrodeposition of MnO 2 into PPy has been also reported for application in electrochemical supercapacitors [47].…”

Length scales of interactions in magnetic, dielectric, and mechanical nanocomposites

“…The Bruggeman theory is unable to distinguish ~o::~een macroscopic and nanoscale effects, because the partial differential equation V\p = 0 does not involve a characteristic length. Nanoscale effects would require (6) 'here 11K can be interpreted as a screening length [4,25,40]. This screening length :\'flect the competition between difterent local and non-local energy contributions and is ;~metimes of the order of a few nanometers.…”

“…Examples are magnet-polymer composites, which have been investigated in the light of future 1pplications such as materials with negative index of refraction [5,6,7].…”

Polypyrrole Composites: Electrochemical Synthesis, Characterizations and Applications

“…PPy-metal nanoparticle composites were electro-co-deposited from a solution containing Py, metal salt as source of metal ions, a suitable neutral salt as supporting electrolyte and small amount of a suitable additive to achieve stability of the metal complex salt. For examples, PPy-Au (Rapecki et al, 2010), PPy/Ni (Haseko et al, 2006), PPy/Fe (Chipara et al, 2007), PPy/Co (Ikeda et al, 1983) and Pd/PPy/foam-Ni (Sun et al, 2010) are some examples of nano composites obtained by this technique.…”
