Method for Fast Crosslinking of Silicone Compounds at Low Temperature By in Situ Water Generation
Introduction Deposition of small amounts of functional materials has recently become a matter of intensive research. Inkjet printing technology is a promising and widely used technique for the fabrication of small parts with specific functionalities into welldefined locations. The limits of this technology are largely based on materials science properties of the “inks” used, such as viscosity, amount of solid in the dispersant liquid, shrinkage of the product, and temperatures required. Processing of preceramic polymers into ceramic products, for example, involves shaping of a low viscous polymer precursor, subsequent curing and pyrolysis at temperatures above 800°C. There exists a need for improved preceramic materials, and methods for making these materials at relatively low temperatures. Technology description Researchers at the University of Washington have invented ceramic products from preceramic polymers that are readily shaped and cured rapidly and at low (e.g., room) temperature. The method involves creating a ceramic product from a liquid polymer that is crosslinked by in situ water generation in a room temperature process. The viscosity of the preceramic polymers is sufficiently low so as to permit inkjet printing as a shaping method. This method improves on traditional ceramic product fabrication because it does not require elevated temperatures and involves much shorter fabrication times. Business opportunity Specialized ceramic polymers can be used in inkjet printing processes for the creation of a wide variety of products. Stage of development Prototypes of this technology are under development Intellectual property position US and PCT patent applications are pending.Type of Offer: Licensing
