Publication number: 20190233607Abstract: A method of synthesizing aerogels and cross-linked aerogels in a single step and in a single pot without requiring any solvent exchange is described. Porous matrices are synthesized through a modification of hydrolysis condensation of alkoxides in which addition of water is minimized. The reaction occurs in an ethanol-water azeotrope mixture; the water in the azeotrope slowly hydrolyzes the alkoxide. Additionally, after gelation, the porous matrix is dried in supercritical ethanol rather than liquid CO2, which allows for elimination of solvent exchange steps. These modifications allow for the preparation of aerogel monoliths in any size in one step and in one pot and much faster than conventional procedures. In addition, the method provides for custom aerogel parts with large dimensions, as well as high volume fabrication of aerogels. The custom aerogel parts may be used in a variety of thermal insulation applications.Type: ApplicationFiled: April 5, 2019Publication date: August 1, 2019Inventor: Massimo Bertino

Publication number: 20190233636Abstract: Novel block copolymers (“BCPs”) having non-random distributions of comonomers within at least one of the blocks and methods of using those BCPs in directed self-assembly (“DSA”) processes are provided. The non-random (e.g., gradient-creating) distributions can be customized in order to concentrate the desired comonomer properties in predetermined areas of the BCP. These BCPs can achieve perpendicular orientation with simple annealing and offer superior long-range ordering and lower defectivity when compared to prior art BCPs. These BCPs can be incorporated into compositions that simultaneously offer the benefits of high-? and rapid thermal-annealing kinetics while maintaining similar or improved guide process windows when compared to prior art BCPs.Type: ApplicationFiled: September 17, 2018Publication date: August 1, 2019Inventors: Kui Xu, Richard Elsworth Daugherty, JR., Daniel Patrick Sweat, Mary Ann Hockey, Eric Calderas, Megan Bennett
