Resumen:

Activated carbon (AC) micro and nano particles were produced from Granular AC. Particle size distribution was measured before and after THF solvation by light dispersion. Particles were incorporated into a matrix of polystyrene via in situ miniemulsion polymerization. The nanostructured latexes were characterized by TEM and by SEM. Triacetate cellulose (TAC) and AC particles composite membranes were produced and analyzed by AFM tapping® for height and face contrast. Particle size after solvation shows a significant decrease in size. We obtained stable latex with particles of less than 100 nm diameter, TEM micrographs show the encapsulation of the AC nanoparticles into the polystyrene matrices. Integration of AC particles into TAC membranes was successfully done, and AFM images show the nanodispersion of these particles.
