Estimating the term…
A method for grafting functional chemical groups to a textile substrate is provided, wherein the substrate is impregnated with a solution of a functional molecule, containing the functional chemical group and a group that is reactive to ionising radiation, as well as a surfactant molecule that can improve the wettability of the textile substrate by the solution. The surfactant molecule contains at least two types of groups that are reactive to ionising radiation. Subsequently, ionising radiation is applied to the impregnated textile substrate and the reaction of the reactive groups bridge-grafts the functional molecules to the surfactant molecules. A textile substrate and a battery separator grafted using the above method are also described.

A method for grafting functional chemical groups on a textile substrate, said method comprising the steps of impregnating said textile substrate with a solution of a functional molecule comprising a functional chemical group and a reactive group in ionising radiation, and a surfactant molecule which is capable of improving the wettability of the textile substrate by said solution, which surfactant molecule comprises at least two types of reactive groups in ionising radiation, and applying ionising radiation on the impregnated textile substrate to graft functional molecules by means of coupling with the surfactant molecules and by means of a reaction of the reactive groups.
