Figure 2From: Core-shell-structured silica/polyacrylate particles prepared by Pickering emulsion: influence of the nucleation model on particle interfacial organization and emulsion stabilitySEM images of composite particles of different ratios of MMA/BA. (a) 1/2, bare acrylic polymer; (b) 1/1, less densely encapsulated; (c) 2/1, well encapsulated. The composite particles were prepared by method 2.Back to article page
