Disclosed is a vesicular system comprising a surface with a vesicle immobilized thereon. The immobilized vesicle has a circumferential membrane of an amphiphilic polymer. The vesicle is coupled to a surface by means of a molecule with a non-polar moiety. The non-polar moiety comprises a main chain of 3 to about 30 carbon atoms and 0 to about 12 heteroatoms selected from Si, O, S, and Se. The molecule with the non-polar moiety is coupled to the surface via a covalent or non-covalent bond. A portion of the non-polar moiety is integrated in the circumferential membrane.

The invention relates to the use of PMMI copolymers for reducing the decrease in molecular weight of the polymer induced by addition of talc in compositions based on aromatic polycarbonate. At the same time, the mechanical, optical and rheological properties of the thermoplastic composition, in spite of the addition of the PMMI copolymer, remain good and are in some cases even improved.

Disclosed herein is a composite material suitable for inhibiting biofilm growth, the composite material comprising a substrate material and a random copolymeric material covalently bonded to a surface of the substrate material. The random copolymer contains repeating units having at least one functional group bearing a cationic charge and repeating units having at least one functional group bearing an anionic charge, where the repeating units are derived from compatible monomers that belong to different monomer classes having differing polymerisation kinetics. Specifically, the random copolymeric material is poly(AMPTMA-ran-SPM), wherein AMPTMA is (3-acrylamidopropyl) trimethylammonium chloride and SPM is 3-sulfopropyl methacrylate potassium. Also disclosed are methods of manufacturing said material and applications thereof.
