Doubly crosslinked microgel-colloidosomes: a versatile method for pH-responsive capsule assembly using microgels as macro-crosslinkers

Abstract

A new family of pH-responsive microgel-colloidosomes was prepared using microgel particles as the building blocks and macro-crosslinker. Our simple and versatile method used covalent inter-linking of vinyl-functionalised microgel particles adsorbed to oil droplets to form shells of doubly crosslinked microgels (DX MGs) and was demonstrated using two different microgel types.
