A facile fabrication of amphiphilic Janus and hollow latex particles by controlling multistage emulsion polymerization.

Highlights: [•] Preparation of morphology controllable latex particles with controlling the multistage emulsion polymerization. [•] Preparation of uniform 100nm asymmetric Janus particles using a partial-encapsulation mechanism. [•] Partially encapsulated acorn-like latex particles with hydrophobic PSt-layer. [•] The hydrophilic cores could be fully encapsulated by the hydrophobic PSt-layer with adding moderate polarity PMMA interlayer. [Copyright &y& Elsevier]
