摘要
A novel two-step assembly method was found and was used to fabricate special multihollow polymer microspheres. Firstly, monodisperse colloidal particles of poly(styrene-co-(n-butyl acrylate)-co-acrylic acid) (P(St-co-nBA-co-AA)) were synthesized by soap-free emulsion polymerization and the obtained emulsion was transferred to 1-octanol to form colloidosomes which were stabilized by Span 80 and the colloidal particles via assembling at the interface of water/oil. Secondly, the multihollow polymer microspheres were successfully fabricated by heat aggregation and fusion of the aforementioned colloidosomes and colloidal particles. The two-step assembly mechanism was revealed and explained based on the morphologies of multihollow polymer microspheres formed under different emulsifier amounts and sintering conditions.
