The present invention relates to a method which uses non-core-shell polymer particles to form polymer film on a pre-formed solid substrate surface, said non-core-shell polymer particles comprising two covalently coupled polymer regions of different molecular composition, wherein (a) one of the two polymer regions is a crosslinked RAFT polymer region and the other polymer region is a film forming polymer region, (b) the crosslinked RAFT polymer region comprising particle aggregation prevention means selected from one or more of charged and steric stabilising functionality, and (c) the film forming polymer region comprising 0-3 wt. % of charged polymerised monomer residues relative to the total amount of polymerised monomer residues present in that region.
A method which uses non-core-shell polymer particles to form polymer film on a pre-formed solid substrate surface, said non-core-shell polymer particles comprising two covalently coupled polymer regions of different molecular composition, wherein (a) one of the two polymer regions is a crosslinked RAFT polymer region and the other polymer region is a film forming polymer region, (b) the crosslinked RAFT polymer region comprising particle aggregation prevention means selected from one or more of charged and steric stabilising functionality, and (c) the film forming polymer region comprising 0-3 wt. % of charged polymerised monomer residues relative to the total amount of polymerised monomer residues present in that region, the method comprising contacting in a liquid the pre-formed solid substrate surface with the non-core-shell polymer particles dispersed in the liquid, wherein the non-core-shell polymer particles adsorb onto the pre-formed solid substrate surface through the film forming polymer region and the film forming polymer regions of the adsorbed non-core-shell polymer particles coalesce to form the polymer film.
Solid substrate having polymer film adsorbed on a surface thereof, said polymer film comprising a plurality of polymer regions that (i) are different in molecular composition to the polymer film, (ii) are covalently coupled to the polymer film, and (iii) comprise (a) crosslinked RAFT polymer, and (b) particle aggregation prevention means selected from one or more of charged and steric stabilising functionality, wherein said polymer film comprises 0-3 wt. % of charged polymerised monomer residues relative to the total amount of polymerised monomer residues present in the film.
Solid particulate material encapsulated in a polymer film, said polymer film comprising a plurality of polymer regions that (i) are different in molecular composition to the polymer film, (ii) are covalently coupled to the polymer film, and (iii) comprise (a) crosslinked RAFT polymer, and (b) particle aggregation prevention means selected from one or more of charged and steric stabilising functionality, wherein said polymer film comprises 0-3 wt. % of charged polymerised monomer residues relative to the total amount of polymerised monomer residues present in the film.
