The present invention provides materials and composite materials comprising layer (A) comprising afirst polysaccharide which has been derivatised to comprise fatty acid ester moieties. Also provided are substrates coated with the material and composite material, and processes for preparing the material, composite material and coated substrate.

A surface coating method comprises heating a coating solution comprising a gelling agent, at least one sulfate salt and water to a temperature above the melting temperature of the gelling agent but below 100C. The heated coating solution is applied onto a plastic surface (12). The coating solution is dried on the plastic surface (12) to obtain a pre-coated plastic surface, onto which a liquid hydrogel is applied. The liquid hydrogel is solidified to form a solid hydrogel (30) adhering to the pre-coated plastic surface. The surface coating (20) enhances the adherence between the solid hydrogel (30) and the plastic surface (12).

A self-disinfecting coating (1) for surfaces: is provided that includes a base matrix (2) and a loading solution (3), the matrix (2) in turn includes a gel base (10) and a gel fluid (7), and the loading solution (3) comprises an active disinfectant ingredient (4), in such a way that the base matrix (2) is able to absorb and retain the active ingredient (4) while maintaining, on the free surface of the coating (1), a sufficient concentration of active ingredient (4), thus maintaining the surface disinfected. The gel base (10) may include a protein of collagen, albumin or elastin and glycerine as the plasticising agent (6). The loading solution (3) may include elemental iodine as an active ingredient (4) and ethanol as the loading solvent (8). The self-disinfecting coating (1) may include a base substrate (11) that includes therein the base matrix (2) and loading solution (3).
