Title (EN) LITHIUM SALT OF POLYACETYLENE AS RADIATION SENSITIVE FILAMENTS AND PREPARATION AND USE THEREOF
(FR) SEL DE LITHIUM DE POLYACETYLENE SERVANT DE FILAMENTS SENSIBLES AUX RAYONNEMENTS, PREPARATION ET UTILISATION DE CELUI-CI
Abstract: front page image
(EN)This invention relates to photochromic filaments composed of the lithium salt of a conjugated, polymerizable polyacetylene having a carboxylic acid or carboxylate terminal group wherein the length to width ratio of said filaments is between about 5000:1 and about 5:1 and the average length of the filament is up to about 5cm. The invention also pertains to the use of said salts in maximized radiation sensitivity for imaging, radiation dose measurement or mapping and detection of radiation fields.
(FR)La présente invention concerne des filaments photochromes composés d'un sel de lithium d'un polyacétylène polymérisable conjugué qui présente un acide carboxylique ou un groupe terminal carboxylate, le rapport longueur sur largeur desdits filaments étant situé entre environ 5000:1 et environ 5:1 et la longueur moyenne de filament s'élevant jusqu'à environ 5 cm. La présente invention concerne également l'utilisation de ces sels avec une sensibilité maximale aux rayonnements dans le cadre d'une imagerie, d'une mesure de dose de rayonnement ou d'une cartographie et d'une détection de champs de rayonnement.
