PPy particles were from 100 to 500 nm with conductivity ranging
from 1 to 3 mS cm
. Recently Kim et al. made PPy nanostructures
in the so-called magnetic IL [82]. They used [BMIM][FeCl

], which is
active under magnetic field and can be considered a paramagnetic
compound [83]. PPy particles were made by self-assembled method
where [BMIM][FeCl
] was mixed with monomer and a magnetic field
was applied resulting in PPy precipitate. Magnetic IL acted threefold:
as dopant, catalyst, and solvent. The self-assembled particles were
spheres of the size ranging from 50 to 100 nm with high electrical
conductivities. Also in a recent paper Pringle et al. utilized [EMIM]
[Tf

N] for synthesis of PPy-gold and -silver composites with
the use of gold chloride and silver nitrate [84]. The use of these
oxidants enabled a simple one-step fabrication of nanocomposites
and IL assisted incorporation of metallic gold and silver into the
polymer structure.
