Abstract:
(EN) APPARATUS AND PROCESS FOR UNIFORM DEPOSITION OF POLYMERIC NANOFIBERS ON SUBSTRATE The present invention relates to an apparatus for the mass production of polymeric nanofibres and their uniform deposition over any substrate. The present invention also provides a method for the manufacture of droplet free polymeric nanofibres by electrospinning process using multi- hole spinnerets. The droplet free polymeric nanofibres of the present invention are preferably of a diameter in the range of 50 nm to 850 nm.
(FR) APPAREIL ET PROCÉDÉ PERMETTANT UN DÉPÔT UNIFORME DE NANOFIBRES POLYMÈRES SUR UN SUBSTRAT La présente invention concerne un appareil de production en série de nanofibres polymères et leur dépôt uniforme sur un substrat quelconque. La présente invention concerne également un procédé de fabrication de nanofibres polymères sans gouttelette par un procédé d'électrofilature utilisant des filières à plusieurs orifices. Les nanofibres polymères sans gouttelette de la présente invention sont de préférence d'un diamètre de l'ordre de 50 nm à 850 nm.
