An antimicrobial composite structure including: a polymeric material, the material having a first exterior surface expanded to fibrils and nodes, a second exterior surface and an interior portion between the exterior surfaces; and nanoparticles present in the interior portion adjacent the first exterior surface but not in the interior portion adjacent the second exterior surface. The nanoparticles can be silver nanoparticles and the polymeric material may be an expanded fluoropolymer material such as expanded polytetrafluoro ethylene. L'invention concerne une structure composite antimicrobienne comprenant : une matière polymère, la matière ayant une première surface externe expansée sous forme de fibrilles et de noeuds, une seconde surface externe et une partie interne entre les surfaces externes; et des nanoparticules présentes dans la partie interne adjacente à la première surface externe mais non présentes dans la partie interne adjacente à la seconde surface externe. Les nanoparticules peuvent être des nanoparticules d'argent et la matière polymère peut être une matière fluoropolymère expansée, telle que du polytétrafluoroéthylène expansé.
