Publication number: 20230279240Abstract: An intumescent coating composition consisting of a binder system and a two-component intumescent package is described. Tannic acid (TA) and ammonium polyphosphate (APP) have exhibited sufficient characteristics to serve as char formers (via TA), blowing agents (via TA), and an acid source (via APP). Such compositions may be incorporated in epoxy and other resin-based coatings. The resulting composition should provide comparable intumescent performance in comparison to existing/available products.Type: ApplicationFiled: March 2, 2023Publication date: September 7, 2023Inventors: Erik PRICE, Gary WNEK, James COVELLO

Publication number: 20160280879Abstract: A process for flame-retarding base materials, such as fibers or foams with a metal oxide, such as silica, nanoparticle-containing composition and materials including a metal oxide, for example silica nano/micro particle-containing coating, layer, or networks. The process utilized allows properties of the coated material to be maintained. Flame-retarded materials are also disclosed. Heterogeneous dispersions of metal oxide, e.g. silica, particles on fibers or foams on a nanometer scale are described and/or the formation of networks/coatings in porous materials. In a particular embodiment, polymeric foams such as polyisocyanurate, polyurea and polyurethane foams include a metal oxide particle-containing coating layer or network that aids in char formation in the event the material is exposed to a flame.Type: ApplicationFiled: March 24, 2016Publication date: September 29, 2016Inventors: Daniel Brannum, Gary Wnek

Patent number: 9040665Abstract: A method of forming a cross-linked protein structures includes preparing a solution of protein dissolved in a benign solvent and forming an intermediate protein structure from the solution. The intermediate protein structure can be cross-linked by providing for a specific ratio of chemical cross-linking agents to form the cross-linked protein structure. The solution can be prepared by adding a cross-linker of N-hydroxysuccinimide (NHS) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC) at a ratio of two-to-one of NHS to EDC to alcohol. PBS buffer (20×) can be added to the solution until the volume ratio of PBS buffer (20×) to alcohol is about one-to-one. About 16 percent by weight of protein can be dissolved in the solution. The solution can be electrospun to form an intermediate protein structure. After a period of time, the protein structure can be cross-linked to form the cross-linked protein structure.Type: GrantFiled: March 26, 2012Date of Patent: May 26, 2015Assignee: Case Western Reserve UniversityInventors: Gary Wnek, Linghui Meng

Publication number: 20130310779Abstract: High-pressure bleeding wounds (and other bleeding wounds) may be treated by applying direct pressure directly in the bleeding wound, such as by applying a back pressure in a confined space around and in the wound. Certain substances and articles may be inserted into the wound, and the wound may be enclosed with that substance or article (such as a hemostatic substance, which may be polymeric), by swelling on contact with molecules (such as water molecules in the blood) encountered in the wound, generates the desired pressure to stop or at least reduce the bleeding without the detrimental effects of a tourniquet. Clot-inducing substances may be introduced into the wound contemporaneously with direct pressure application directly in the wound. Compressible and non-compressible wounds are treated. Treatment stops bleeding without producing pressure injury or ischemic damage. Medical devices using this technology are provided, including removable, biodegradable, medic-administrable devices.Type: ApplicationFiled: July 26, 2013Publication date: November 21, 2013Applicant: Virginia Commonwealth UniversityInventors: Gary Wnek, Marcus E.

Patent number: 7442754Abstract: Small particles of polymeric material are produced by expansion of a mixture of monomers and a propellant. The size and shape of the particles can be precisely tailored by materials selection and expansion conditions. Particles of 10 nanometers to 100 microns can be produced. If monomers exhibiting solid state reactivity are utilized, the particles thus formed can be polymerized at any time after formation. The particles produced by this method can be molecularly imprinted by incorporating a template into the particle prior to fully curing the particle, in a manner which allows selective extraction of the template from the cured particle after formation without deformation of the imprint site. A two step polymerization process allows the particles to be deposited on and adhered to a wide variety of substrates without additional agents.Type: GrantFiled: October 10, 2003Date of Patent: October 28, 2008Assignee: Virginia Commonwealth UniversityInventors: Gary Tepper, Dmitry Pestov, Natalia Levit, Gary Wnek
