We synthesized a diblock copolymer and grafted it onto fumed silica in the presence of trifluoroacetic acid to obtain a pH-responsive Pickering emulsion system stabilized by polymer-coated nanoaggregates, P-Si.
Xylene-in-water Pickering emulsion stabilized by polymer particles that were fabricated by the self-assembly of amphiphilic double dynamers showed temperature- and pH-responsive demulsification feature.
In this work, prochloraz pH-responsive nanocapsules were developed by the Pickering emulsion polymerization method with isophorone diisocyanate (IPDI) and nano Fe3O4 particle-branched polyethyleneimine (PEI).
