a High-resolution transmission electron microscopic (HRTEM) images of PANS. Scale bar is 100 nm, and inset is a high magnification image. b XPS C1s spectra of bare polyaniline (bPAni) (upper) and PANS (lower). 1: C=O/C–O, 2: C–N+/C=N+, 3: C–N/C = N, 4: C–C/C–H. c FTIR spectra of bPAni (upper) and PANS (lower). An asterisk represents a interesting peak described in more detail in the text. d Thermogravimetric analysis (TGA) of bPAni (upper) and PANS (lower). e Surface area (bar) and pore volume (line and scatter) of bPAni and PANS using Brunauer–Emmett–Teller (BET) analysis. f Size distribution of PANS via dynamic light scattering (DLS) method
