Title (EN) FINE FEATURED MOLDINGS OF LIQUID CRYSTALLINE POLYMERS
(FR) PIECES MOULEES A MOTIFS FINS CONSTITUEES DE POLYMERES A CRISTAUX LIQUIDES
Abstract: front page image
(EN)Liquid crystalline polymers may be melt formed with very fine features such as ridges and/or channels molded into the resulting solid article. Ridges and/or grooves as little as 0.1 micron wide and/or a little as 10 nm deep and/or ridges or grooves as little as 0.2 micron apart may be molded into LCPs under the proper molding conditions. Other features of similar sizes, such as depressions or high points, may also be molded into LCP parts. These articles are useful as and/or may be readily converted to diffraction gratings, printed circuits, and other useful items.
(FR)La présente invention concerne des polymères à cristaux liquides, qui peuvent être fondus et pourvus de motifs très fins, tels que des saillies et/ou des canaux, moulés dans l'article solide résultant. Des saillies et/ou des rainures de 0,1 micron de large et/ou de 10 nm de profondeur et/ou des saillies ou des rainures espacées de 0,2 micron peuvent être moulées dans des polymères à cristaux liquides (liquid crystalline polymer : LCP) dans des conditions de moulage adéquates. D'autres motifs de dimensions similaires, tels que des dépressions ou des points hauts, peuvent également être moulés dans des pièces en polymères à cristaux liquides. Ces articles sont utilisés en tant que/peuvent être facilement convertis en réseaux de diffraction, en circuits imprimés et en d'autres objets utiles.
