Crosslinked polymeric nanocapsules with controllable structure via a 'self-templating' approach.
We developed a novel strategy for the near-monodispersed crosslinked polymeric nanocapsules with controllable structure via the 'self-templating' approach by the following four steps: (i) preparation of the PVAc lattices by the emulsion polymerization of VAc; (ii) surface hydrolysis of the PVAc lattices; (iii) crosslinking the PVA segments on the surface of the surface-hydrolyzed PVAc lattices and (iv) removal of the PVAc core of the core-shell structures by being dissolved by methanol. The strategy developed was confirmed with Fourier-transform infrared, transmission electron microscopy and dynamic light scattering techniques. In the strategy developed, the particle size, the thickness and the crosslinking degree of the nanocapsules could be controlled with the lattice's size, relative molecular weight of PVAc and the crosslinking degree of the crosslinked shell.
