Processes for chemical functionalization of materials are described. The processes generally include chemical reaction between a thiol group of a first compound or material and an alkene group or alkyne group of a second compound or material. Also disclosed are functionalized materials and compounds suitable for functionalizing a material.

The invention relates to a crosslinkable composition comprising functionalized monomers comprising a crosslinkable group, a cationic group and a fluorinated group, wherein the composition comprises anions corresponding to the cationic groups of the functionalized monomers, wherein the cationic group is an N-substituted cyclic and in particular heteroaromatic group comprising a 5-membered ring and/or at least two heteroatoms and wherein a spacer which is an uncharged and unfluorinated organyl group and preferably an alkylene group is arranged between the cationic group and the fluorinated group.

Polyethylene support in form of net or fabric, comprising, grafted on the surface of said support, a hydrogel comprising polyvinylpyrrolidone. Method for preparing said support comprising the steps of: immersing the support in a toluene solution (Sol1) containing: ethylene glycol dimethylacrylate (EGDMA) and cumene hydroperoxide (CHP); immersing the support in an aqueous solution (Sol2) containing: FeCl2*4H2O, ascorbic acid and polyvinylpyrrolidone (PVP); washing and drying the support.
