To tune the surface wettability of Cu2(OH)2CO3 microspheres, polystyrene nanoparticles were attached to their surfaces via a dispersion polymerization. The products were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transmitting infrared spectrum (FT-IR). The immersion times of the modified Cu2(OH)2CO3 microspheres in a water-methanol mixed solution were measured. The results showed that with the increase of the size of the attached polystyrene nanoparticles, the hydrophobicity of the modified Cu2(OH)2CO3 microspheres was enhanced. Using polystyrene nanoparticle-attached Cu2(OH)2CO3 microspheres with intermediate hydrophilicity as emulsifiers, stable water-in-tricaprylin Pickering emulsions were produced. By gelling the water droplets of the Pickering emulsions, the hierarchical structures of polystyrene nanoparticle-modified Cu2(OH)2CO3 microspheres-armored agarose gel microspheres were obtained.
