A convenient method for the preparation of bead–string shaped and core–shell attapulgite@polystyrene (ATP@PS) composite particles through emulsion polymerization from needle‐shaped attapulgite is reported. The pretreatment of attapulgite with cetyltrimethylammonium bromide (CTAB) in ultrasonic is essential for successful encapsulation and for creating strong interfacial interaction between attapulgite and polystyrene (PS). The different morphologies of the ATP@PS particles, bead–string shaped and core–shell shaped, obtained with different amounts of styrene charges, were characterized by transmission electron microscopy (TEM). Encapsulation mechanisms of the two morphologies were also developed. Copyright © 2007 John Wiley & Sons, Ltd. |
