Abstract:
1. Method for preparing a membrane comprising a polymer matrix and at least one mineral filler functionalized by at least one group comprising a single sulfur atom in the form of a thioester (—S—), thiocarbonyl (—C(═S)—) or sulfinyl (—S(═O)—), said method comprising the steps of: a) preparing a mineral filler functionalized by at least one group comprising a single sulfur atom in the form of a thioester (—S—), thiocarbonyl (—C(═S)—) or sulfinyl (—S(═O)—), by using a compound derived from silane of general formula SiR the radicals R the radical R b) combining the functionalized mineral filler prepared at step (a) with a polymer matrix whereby said membrane is obtained.
