One-step synthesis of silica@resorcinol-formaldehyde spheres and their application for the fabrication of polymer and carbon capsules.

Core@shell spheres made up of a thin layer of resorcinol-formaldehyde enveloping a silica core were prepared by means of a one-step method under Stöber conditions. These spheres are used as a platform for the synthesis of carbon or polymeric capsules, and functionalized nanocomposites.
