Patent number: 10703843Abstract: The present application provides compositions and methods for allowing surfaces such as HDPE, LDPE, polyethylene, polypropylene, Teflon (polytetrafluoroethylene), SBS, SEBS, SIS elastomers, and silicone rubber, which are notoriously difficult to apply adhesives, glues, or coatings to, to be treated with a Primer System comprising a cyanoacrylate monomer and non-polar solvent component and an initiator component, wherein the polymerization product of the components is a microstructured polycyanoacrylate layer. The microstructured polycyanoacrylate layer-increases the ability of a glue, adhesive, or coating to adhere to that surface and subsequently allows other materials to be used as coatings on the surface or to be applied using a glue or adhesive.Type: GrantFiled: December 7, 2015Date of Patent: July 7, 2020Assignee: University of Virginia Patent FoundationInventor: Louis A.

Patent number: 10358528Abstract: The invention provides for new viscoelastic silicone rubbers and compositions and methods for making and using them. The invention provides for viscoelastic silicone rubbers that are stiffer on short timescales than they are on long timescales. When subjected to brief stresses, they are relatively stiff and elastic, and they resist changing shapes. When subjected to sustain stresses, however, they are relatively soft and accommodating, and they gradually change shapes. When those stresses are removed, they gradually return to their original shapes. These viscoelastic silicone rubbers resist compression set and they are extremely resilient in response to sudden impacts. They can be dense rubbers, foam rubbers, and particles.Type: GrantFiled: May 31, 2018Date of Patent: July 23, 2019Assignee: UNIVERSITY OF VIRGINIA PATENT FOUNDATIONInventor: Louis A. Bloomfield

Patent number: 9102799Abstract: This invention relates to viscoelastic silicone rubber compositions that are the products of the reaction of: (a) a silanol-terminated polyorganosiloxane base; (b) a boron-containing crosslinking agent; and (c) a siloxane bond-forming crosslinking agent. In a viscoelastic silicone rubber composition of the invention some of the crosslinks, the siloxane crosslinks, are permanent and others of the crosslinks, the boron-containing crosslinks, are temporary. Because a fraction of its crosslinks can come apart and then reform, a viscoelastic silicone rubber composition of the invention can relax stress in response to strain and thus adapt to new shapes. The composition has sufficient permanent crosslinks, however, to establish a permanent equilibrium shape to which the composition will eventually return when not subject to any imposed stress.Type: GrantFiled: July 21, 2014Date of Patent: August 11, 2015Assignee: University of Virginia Patent FoundationInventor: Louis A.

Publication number: 20090286910Abstract: A device and related method having an elastic means and a damping means for controlling motion between objects or bodies. The elastic means and the damping means may be combined together to form a composite material, for which there is a method of use and manufacture. The device and related method may also utilize a dilatant-based material to oppose the rapid relative motion of two members. The objects or bodies, for example, may be a piece of furniture and the floor. In its application to furniture, this device and related method acts to keep all the legs on a piece of furniture in contact with the floor so that there is no rocking, and it acts to make those legs rigid on short timescales so that there is no bouncing or apparent unsoundness of the support.Type: ApplicationFiled: May 25, 2007Publication date: November 19, 2009Applicant: UNIVERSITY OF VIRGINIA PATENT FOUNDATIONInventor: Louis A.
