•Synthesis of P(DVB-co-GMA)-NH2@SiO2/P(DVB-co-GMA) particles.•Raspberry-like particles via heterocoagulated reaction.•Heterocoagulated reaction between epoxy and amino groups.•Superhydrophilicity of polycarbonate film coated with raspberry-like particles.
The core–corona polymer hybrid particle with a raspberry-like structure was prepared by a heterocoagulation through the chemical reaction between the epoxy groups of silica/poly(divinylbenzene-co-glycidyl methacrylate) (SiO2/P(DVB-co-GMA)) core–shell small microspheres and the amino groups of amino-modified poly(divinylbenzene-co-glycidyl methacrylate) (P(DVB-co-GMA)-NH2) microspheres, in which SiO2/P(DVB-co-GMA) acted as the corona and P(DVB-co-GMA)-NH2 behaved as the core. The film of resultant raspberry-like hybrid particles with dual-size structure had an average contact angle (CA) of 141.8°, indicating great prospects in the super-hydrophobic applications. The resultant polymer microspheres and raspberry like particles were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), Fourier transform spectra (FT-IR), elemental analysis (EA) and contact angle system (CA).
