Abstract:Activated carbon from inexpensive sources has been of great interest for separation systems, efforts had been made to produce AC nanoparticles by different means, in the aim to integrate them to composite materials to enhance their characteristic efficiency. Recently a very inexpensive method to produce AC nanoparticles by solvatation was proposed. The objective of this work is to study this production of AC particles and use different methods to characterize their average particle size and the possibility to fully disperse them into a polymeric matrix. AC micro and nano particles were produced from Granular AC. Particle size distribution was measure before and after the solvatation by laser diffraction. AC Particles were incorporated, into a matrix of polystyrene via in situ miniemulsion polymerization. The nanostructured latexes were characterized by TEM and SEM. Triacetate cellulose(TAC) and AC particles composite membranes were produce and analyzed by AFM tapping® for height and face contrast. Particle size after solvatation shows a significant decrease in size. We obtained stable latex with particles of less than 100 nm diameter, TEM micrograph show the encapsulation of the AC nanoparticles into the polystyrene particles. Integration of AC particles into TAC membranes was successfully done, and AFM images show the nanodispersion of these particles.
