Fig. 3From: New nanocomposites of polystyrene with polyaniline doped with lauryl sulfuric acidFTIR spectra of PS nanoparticles (1), PANI-LSA (2), and NC15 (3): a spectrum 4 is the result of subtraction of the normalized PS spectrum from the NC15 one, b spectrum 4 is the sum of the PS spectrum (normalized to the band height of NC15 at 3025 cm−1), and the PANI-LSA spectrum (normalized to the band height of NC15 at 1560 cm−1)Back to article page
