Interests on polyamidoamine (PAMAM) dendrimers have been rising recent decades, due to their high applicability in many research fields such as drug delivery, encapsulation, and metal ion absorption. Abundant amine groups in PAMAM facilitate heavy metal ions and gases absorption/adsorption in the polymer. However, PAMAM dendrimer requires long, tedious and costly synthetic steps to obtain high molecular weight without defects. In this study, we carried out a simple one-step synthesis of hyperbranched PAMAM, which is an analogue of dendrimers, in the shape of particle from inverse suspension polymerization. With Oil-in-Water-in-Oil (O/W/O) polymerization, we also obtained porous PAMAM particles. Copper (II) ion absorption test revealed that the synthesized PAMAM particles showed a high metal ion absorption capacity. |
