Preparation and recyclable catalysis performance of functional macroporous polyHIPE immobilized with gold nanoparticles on its surface.

ABSTRACT: High internal phase emulsion polymerization was adopted for preparing macroporous polymeric monoliths, polyHIPE-Br (PHIPE-Br). Macroporous PHIPE-Br was used as the initiator to initiate the atom transfer radical polymerization (ATRP) of glycidyl methacrylate (GMA), resulting in a dense coating of polymers on the PHIPE surface and PHIPE-PGMA was obtained. Through a ring-opening addition reaction with TETA, a surface amino-polymer modified functional macroporous PHIPE-PGMA-TETA, was prepared conveniently. Gold nanoparticles could be easily in situ prepared and immobilized on the surface of PHIPE-PGMA-TETA. Characterization by scanning electron microscopy (SEM), EDX-mapping and TGA showed that PHIPE-PGMA-TETA was immobilized by the gold nanoparticles, and presented good catalytic prope
