An electrospinning device is described for producing fibrous porous structures. The device is adapted for providing a predetermined distance profile for the distance between outlets of the electrospinning device and the receiving surface. The latter may be obtained by geometrically adapting the electrospinning device or by moving the outlets with respect to the receiving surface during growth of the fibrous structure. A fibrous structure obtained by the described electrospinning device is also described which comprises fibres, wherein the diameter of the fibres has a predetermined profile along a dimension of the electrospun fibrous structure. Furthermore application of the laminated structure for wound dressing and teeth bleaching is discussed.

L'invention concerne un dispositif d'électrofilature pour produire des structures poreuses fibreuses. Le dispositif est apte à fournir un profil de distance prédéterminé pour la distance entre des sorties du dispositif d'électrofilage et la surface de réception. Ce dernier peut être obtenu par l'adaptation géométrique du dispositif d'électrofilage ou par le déplacement des sorties par rapport à la surface de réception pendant la croissance de la structure fibreuse. Une structure fibreuse obtenue par le dispositif d'électrofilage décrit est également décrite, laquelle comprend des fibres, le diamètre des fibres ayant un profil prédéterminé le long d'une dimension de la structure fibreuse électrofilée. L'invention concerne également une application de la structure feuilletée pour un pansement de blessure et un blanchiment des dents.
