Zeolitic imidazolate frameworks (ZIF-8) is a kind of metal organic framework (MOF). Basically, they can be made from zinc ions coordinated with four imidazolate rings. They have chemical and thermal stability which make ZIFs capable of diverse applications, such as gas storage, separation, heterogeneous catalysis and chemical sensing. However, the ZIF-8 in form of nano-sized powder is difficult to handle and collect after used. The aim of project is to improve the stability of individual ZIF-8 by incorporating with polymeric particles. Polystyrene (PS) has been selected since its simple preparation method, size variation and functionalization ability. NanoZIF-8 loaded PS composite particles are prepared via two methods (i) dispersion polymerization of styrene with ZIF-8 and PVP in one step and (ii) polystyrene particles are prepared prior surface functionalization of PS particles and generate ZIF-8 on the PS particle surface. The composite particles prepared via one step method exhibited the ZIF-8 embedded in the particles surface, while two step method created the ZIF-8 attached on the particles surface as shown in Fig. 1. XRD patterns confirmed the present of ZIF-8 on the composite particles surface. This composite particles can be used as absorbent materials or applied for waste water treatment.
