Abstract (en)
[origin: WO2021214420A1] The invention relates to a composite membrane (1), said membrane comprising at least one fabric (2), said membrane comprising a surface polymer layer (41, 42), said surface polymer layer (41, 42) comprising silver and at least one polymer selected from the group consisting of fluorinated polymers and silicones, and said membrane being such that the silver (4; 40) is in the form of silver supported by a mineral matrix in powder form, the particle size of the matrix being strictly greater than 0.1 μm and strictly less than 20 μm. The invention further relates to a method for manufacturing a membrane according to the invention. The invention further relates to a use of a membrane (1) according to the invention as a virucide.
