indicating the formation of a comonomers/
TX-100 complex. From this experimental
result, one can deduce that comonomers (aniline
and pyrrole) are solubilized in the spherical micelle
formed by TX-100, however, it is still necessary
to discuss the location of comonomers (aniline
and pyrrole) in the micelles for understanding
their detailed copolymerization courses. As
reported, aniline molecules are mainly located
in the outside of micellar palisade layer with the
phenyl group close to the hydrophobic part of
TX-100 and NH2 toward the aqueous
phase.42–46 Different from aniline monomer, the
hydrophobic behavior of pyrrole monomers molecule
make them easy to enter the micellar interiors,
such as the micellar palisade layers and
cores.47,48 In this way, TX-100 micelles are
swelled by the solubilization of aniline and pyrrole
at different locations of the micelles, accompanied
with the sized increase. However, it
should be pointed out that there are aniline and
pyrrole monomers dispersing in the bulk solution
because two comonomers are still soluble in
aqueous phase.49
