Initiated chemical vapor deposition enables an all-dry encapsulation of fine particles down to the nanoscale by functional polymers. Initiator vapor is first thermally activated to form primary radicals, which, together with the monomer vapor, are adsorbed onto the particle surface where free-radical polymerization creates a stoichiometric polymer coating (see figure). This polymer coating can subsequently be immobilized with other desired functional molecules.
