Patent number: 8951639Abstract: A method of making capsules includes forming a mixture including a core liquid, a polyurethane precursor system, a first component of a two-component poly(urea-formaldehyde) precursor system, and a solvent. The method further includes emulsifying the mixture, adding a second component of the two-component poly(urea-formaldehyde) precursor system to the emulsified mixture, and maintaining the emulsified mixture at a temperature and for a time sufficient to form a plurality of capsules that encapsulate at least a portion of the core liquid. The capsules made by the method may include a polymerizer in the capsules, where the capsules have an inner capsule wall including a polyurethane, and an outer capsule wall including a poly(urea-formaldehyde). The capsules may include in the solid polymer matrix of a composite material.Type: GrantFiled: March 16, 2012Date of Patent: February 10, 2015Assignee: The Board of Trustees of the University of IllinoisInventors: Scott R.

Patent number: 8679621Abstract: An autonomic conductivity restoration system includes a solid conductor and a plurality of particles. The particles include a conductive fluid, a plurality of conductive microparticles, and/or a conductive material forming agent. The solid conductor has a first end, a second end, and a first conductivity between the first and second ends. When a crack forms between the first and second ends of the conductor, the contents of at least a portion of the particles are released into the crack. The cracked conductor and the released contents of the particles form a restored conductor having a second conductivity, which may be at least 90% of the first conductivity.Type: GrantFiled: June 20, 2011Date of Patent: March 25, 2014Assignee: Board of Trustees of the University of IllinoisInventors: Benjamin J.

Publication number: 20130171484Abstract: An autonomous battery shutdown system includes a battery including an anode and a cathode, and an electrolyte composition between the anode and the cathode. The electrolyte composition includes an ionically conductive liquid containing lithium ions, and temperature-sensitive particles including a polymer having a melting temperature between 60° C. and 120° C. When the temperature of the battery exceeds 120° C., the temperature-sensitive particles form an ion barrier that traverses the battery. The resulting shutdown battery may have a specific charge capacity that is more than 98% lower than the specific charge capacity of the original battery.Type: ApplicationFiled: June 6, 2012Publication date: July 4, 2013Applicant: The Board of Trustees of the University of IllinoisInventors: Marta B.
