摘要：
Hollow spherical microcapsules are realized using evaporation induced self assembly of silica nanoparticles by spray drying method. Nanoparticles in spray droplets get jammed, during water evaporation, in an anisotropic fashion, at droplet air-water interface by the action of attractive capillary force. Two levels of structural hierarchy of the microcapsules are investigated using small-angle neutron scattering and scanning electron microscopy.
