L'invention concerne une membrane composite continue poreuse, ainsi qu'un procédé de fabrication associé. L'invention concerne plus particulièrement un procédé de fabrication de ladite membrane, dans lequel des particules fines présentant une taille comprise entre quelques nanomètres et quelques micromètres, ou des particules solides améliorant la fonctionnalité, sont dispersées de manière uniforme, ce qui permet d'améliorer les propriétés physiques de la membrane. La présente invention permet de modifier aisément l'épaisseur de la membrane, et elle est adaptée à la production en série. Selon l'invention, cette membrane composite continue poreuse peut se présenter sous la forme d'une structure de film mince. La membrane selon l'invention peut être appliquée sur un composant électrique/électronique, tel qu'un condensateur en céramique multicouche, un revêtement, une structure d'échafaudage médicale, un électroluminescent organique, un écran à plasma, une membrane polymère poreuse biodégradable, une membrane poreuse pour filtre, une membrane de catalyseur/électrode/filtration pour pile à combustible et analogues, sur lequel il est difficile d'appliquer un revêtement classique.
