  • Patent number: 11306190
    Abstract: A method for modifying a polymeric surface is disclosed. The polymeric surface is activated utilizing atmospheric pressure plasma. An atom transfer radical polymerization initiator is then coupled to the activated surface. A monomer is then polymerized on the activated surface utilizing an activators regenerated by electron transfer (ARGET) atom transfer radical polymerization (ATRP) process. The method enables brush-modification of the polymeric surface, even if the polymeric surface is substantially chemically inert. By way of example, the method enables a chemically inert, substantially hydrophobic polymer surface to be functionalized with substantially hydrophilic polymer brushes. The methods of the present disclosure have general applicability to a myriad of implementations where tunable surface chemistry is advantageous, such as filtration membranes, marine surfaces, and medical devices seeking a biocompatible coating.

  • Patent number: 11124605
    Abstract: The invention provides antimicrobial polypeptides (AMPs) with high radial amphiphilicity. Unlike typical AMPs characterized by facial amphiphilicity or biomimetic antimicrobial polymers with randomly distributed charged and hydrophobic groups, these new AMPs are homo-polypeptides with radially amphiphilic structure. They adopt a stable ?-helical conformation with a hydrophobic helical core and a charged exterior shell, formed by flexible hydrophobic side chains with terminal charge group. The radially amphiphilic polypeptides offer several advantages over conventional AMPs with regard to stability against protease and simplicity of design. They also exhibit high antibacterial activity against both Gram-negative and Gram-positive bacteria and low hemolytic activity. The AMPs thus provide a general platform for treating drug-resistant bacterial infections.

  • Patent number: 10022888
    Abstract: A fireproof material incorporating aerogel with a wood material and a method for making the same are provided. The method is carried out as follows: A. a mixed solution of a precursor and an organic solvent is added with an acid catalyst and becomes an aerogel solution through hydrolysis; B. the aerogel solution is added with an aqueous alkali catalyst solution and forms an aqueous aerogel solution through condensation; C. a wood material is impregnated with the aqueous aerogel solution such that aerogel generated by gelation covers the wood material; and D. the wood material is dried and then shaped to produce a fireproof material. The fireproof material is highly proof against fire and can pass the limiting oxygen index test.

  • Patent number: 9987116
    Abstract: The present invention relates to medical prostheses and methods of manufacturing those devices. In particular, the prostheses are temporarily stiffened meshes with particular coatings to provide initial stiffness and thereby permit easier surgical handling for treatment or reconstruction of soft tissue defects. Preferred embodiments include surgical meshes coated with one or more biodegradable polymers that can act as a stiffening agent by coating the filaments or fibers of the mesh to temporarily immobilize the contact points of those filaments or fibers and/or by increasing the stiffness of the mesh by at least 1.1 times its original stiffness. The devices of the invention can also provide relief from various post-operative complications associated with their implantation, insertion or surgical use.

  • Patent number: 9938190
    Abstract: Grouts, grout products and methods of applying such grouts that include a urethane-acrylic hybrid polymer dispersion (UA-HPD) and a filler material. The UA-HPD may be present in an amount of about 10-40% by weight of the composition, while the filler material may be present in an amount of about 60-90% by weight of the composition. Additional filler materials may also be provided within the UA-HPD grout composition to provide the resultant UA-HPD grout with desired characteristics and properties. The UA-HPD containing grouts are applied between spaced-apart tiles and/or masonry to fill voids and/or joints there-between.

  • Patent number: 9878480
    Abstract: A method of making synthetic polymer pellet feedstock having a high concentration of an anti-microbial agent includes the steps of: introducing a polymer into a mixing vessel; introducing a polysiloxane dispersant into the mixing vessel; introducing an anti-microbial agent comprised of a powdered metal material into the mixing vessel; heating and mixing the polymer, the polysiloxane dispersant and the anti-microbial agent to form a molten blend that exhibits a generally homogenous dispersal of the anti-microbial agent; extruding the molten blend to form filaments; and cutting the filaments to form metalized synthetic polymer pellet feedstock. The powdered metal material includes particles of silver in metallic or salt form measuring between about 2 micrometers and about 12 micrometers and particles of copper in metallic or salt form measuring between about 2 micrometers and about 12 micrometers.
