Seed Adsorption Synthesis and Characterization of PMMA/PAN Particles with Core-Shell Structure

Abstract:

Narrowly-distributed poly (methyl methacrylate)/polyacrylonitrile (PMMA/PAN) core-shell particles with a target use as the precursor for fabricating carbon microspheres and carbon nanotubes (CNTs) were prepared using the seed adsorption method. PMMA, acrylonitril (AN) and potassium persulfate (KPS) were used as the seed latex, the second-stage monomer (shell monomer) and the initiator, respectively. The effect of process parameters, such as monomer adsorption time, monomer/initiator stoichiometry, presence of surfactant as well as reaction temperature and stirring strength etc., on the morphology and size distribution of the PMMA/PAN composite particles was studied. The process condition under which uniform PMMA/PAN composite particles can form was then identified. Morphological observation by SEM revealed that upon the formation of the core-shell structure, smooth surface of PMMA spheres changed into rambutan-like rough structures.
