Abstract:
1. A method of coating a particle, the method comprising: (a) providing a particle, wherein the surface of the particle comprises functional groups suitable to undergo a coupling reaction with at least one of a hydroxyl group, a halogen group, and an alkoxy group; (b) providing molecules of a compound of general formula (Ia) and/or (Ib) (c) contacting the molecules of the compound of general formula (Ia) and/or (Ib) and the particle, thereby forming a first mixture; (d) exposing the first mixture to reaction conditions suitable for a coupling reaction between the functional groups on the surface of the particle and R (e) adding molecules of a compound of the general formula (IIa) and/or (IIb) (f) exposing the second mixture to ultrasound, thereby (i) allowing the formation of covalent links by an intermolecular reaction between functional groups E of the precoating formed in (d) and functional groups K of molecules of the compound of general formula (IIa) and/or (IIb) added in (e), and (ii) providing sufficient energy to allow cross-linking of the molecules of the compound of general formula (IIa) and/or (IIb), such that a coating is formed on the particle.
