A film comprising a permeable polymer matrix provided with one or more functional groups and, embedded within said polymer matrix, one or more nanoparticles of an inorganic substance.
A method for applying a film onto a surface of a suitable substrate, said method comprising the steps of:
- depositing and polymerising a monomer comprising one or more functional groups by plasma polymerisation to form a permeable polymer matrix on said surface;
- (ii) complexing an inorganic substance to said functional groups, and
- (iii) reducing said inorganic substance to form one or more nanoparticles of said inorganic substance;
- wherein said one or more nanoparticles of said inorganic substance is embedded within said polymer matrix.
