This paper reports the first Pickering high internal phase emulsion (HIPE) system stabilized solely by worm-like nanoaggregates. The cross-linked worms were prepared from dispersion polymerization of benzyl methacrylate (BzMA),with poly(dimethylamino ethyl methacrylate) (PDMA) macro-CTA as the stabilizer and ethylene glycol dimethacrylate(EGDMA) as the cross-linker, through polymerization-induced self-assembly (PISA). The effects of internal phase type and volume, as well as worm concentration on the stability of resulting Pickering HIPEs were investigated. Furthermore, by adding small amount silica nanoparticles or magnetic nanoparticles as binder in the continuous aqueous phase, followed by freeze-drying, 3D hierarchical porous monoliths of ultralow density were successfully prepared. This work demonstrated that Pickering HIPE templating provides a facile approach for preparation of ultra-light functional hybrid porous materials, which have good potential in various application areas.
