Descrição: dc.descriptionBlends of polyaniline (PAni) and poly(methyl methacrylate) (PMMA) have been produced using core-shell particle synthesis, which is advantageous because it allows changing surface-related properties of PMMA with relatively small amounts of PAW and without the use of organic solvents. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) measurements indicated that the deposition of pollyaniline seems to alter the regular shape of the primary acrylic latex particles. The coverage of PMMA particles by PAW was confirmed by FTIR measurements, where distinct data were obtained from the transmission and diffuse reflectance modes, since the latter is surface sensitive. The zeta potential, which is also a surface-related property, increased with the contents of PAW, as the shells probably became protonated with PAW in the emeraldine salt form. Coverage with PAW did not affect the thermal bulk properties of the PMMA shells.-
