Abstract: Conductive clay–polymer nanocomposites were prepared via the in situ polymerization of
aminoacetophenone and/or aniline monomers (at initial “aminoacetophenone:aniline”) in the presence
of polyhydroxy iron cation–modified montmorillonite (MMT-PIC). Fourier transform infrared spectroscopy
analysis demonstrated the characteristic bands of the MMT-PIC polymers/copolymers. The
morphological properties analyzed and imaged through X-ray diffraction and scanning electron microscopy,
respectively, displayed an increasing interlayer distance with the mass loading of PIC and
poly(aminoacetophenone-co-aniline) (poly(AAP-co-ANI)), affording intercalated nanocomposites.
Energy-dispersive X-ray spectroscopy measurements revealed that the clay experienced a cation exchange
of sodium by the PIC, and poly(AAP-co-ANI) was present in large amounts on the nanocomposite
surface. The electrical conductivity of the obtained nanocomposites was 5.760 × 10−5 S⋅cm−1.
Moreover, the electrochemical behavior of the polymers extracted from the nanocomposites was studied
via cyclic voltammetry; the redox processes indicated that the polymerization into activated carbon
produced electroactive polymers.
