Title: Innovations of Jacques Le Moigne
Introduction
Jacques Le Moigne is a notable inventor based in Strasbourg, France. He has made significant contributions to the field of materials science, particularly in the development of innovative coatings and temperature indicators. With a total of 3 patents, his work has garnered attention for its practical applications and scientific advancements.
Latest Patents
One of Le Moigne's latest patents is a method for forming coated monocrystalline products. This invention involves a polydiacetylene coating layer deposited upon an organic microcrystal. The coating boasts a large, uniform surface area that is monoriented and free of cracks. The preferred embodiment utilizes a layer of [1,6-di-n(carbazolyl)-2,4-hexadiyne] deposited by epitaxy onto an acid orthophthalate monocrystal of an alkali metal, ammonium, or thallium. The process includes cleaving the acid orthophthalate monocrystal along its (001) plane, depositing a diacetylenic monomer onto the cleaved face of the crystal by heat evaporation under vacuum conditions, and polymerizing the monomer upon the crystal face. The coated layer can be removed from the crystalline substrate by applying a composition such as carbon or an acrylic polymer to form a backing and separating the resultant monoriented film from the crystal by partially immersing the coated crystal in water.
Another significant patent involves temperature indicators based on polydiacetylene compounds. This invention allows for the detection of whether an article has ever exceeded a selected temperature. The polydiacetylene compound is either deposited on a substrate or mixed with a thermoplastic material. It instantaneously and irreversibly changes color from blue to red at the threshold temperature, providing a clear visual indication of temperature exposure.
