摘要
US hollow spherical particles with different sizes have been prepared using core/shell fabrication method with poly-(styrene-acrylic acid) (PSA) latex particles as template. The sodium salt of extractant P204 (di-(2-ethylhexyl) phosphoric acid) was used firstly as the emulsifier in the template synthesis. The diameters of the polymer core decreased from 300 to 120nm on average with increasing of the amount of emulsifier from 1.56 to 3.54%. As a result the diameters of the hollow spheres ranged from 350 to 150 nm. The products were characterized by TEM, IR and XRD, respectively. (c) 2005 Elsevier B.V. All rights reserved.
