Non-woven nano-fiber membranes have unique structures that are interconnected and bicontinuous. They can form supports resembling trusses and be integrated into a top nano-porous layer as a nano-composite. Such a new format has high-flux and low-fouling properties for nano- and ultra-filtrations in water purification.
Single Wall Carbon Nanotubes for Applications - David Arthur, SouthWest NanoTechnologies, Inc.
Three different SWNT product familes are discussed, all made using variations of the CoMoCAT® process. Advances in selective synthesis technology, combined with investment in large scale reactors, are soon expected to significantly reduce barriers to adoption of SWNTs in a variety of near-term applications.
Liquid Wetting and Flow in Nano-Fibrous Systems: Multi-scale and Heterogeneous - You-Lo Hsieh, University of California at Davis
Superhydrophobic Surfaces Generated from Water-Borne Responsive Colloidal Systems- Sergiy Minko, Clarkson University
The objective of this research was the fabrication of superhydrophobic surfaces by deposition of the aggregates of nanoparticles from water-born solutions with no surfactant application. This approach to superhydrophobic surfaces is important for technologies which avoid organic solvents, surfactants, and applications of complex methods for the fabrication of functional surfaces.
Nano Scale Polymerization and Fiber Spinning - Karl Jacob, Georgia Institute of Technology
Nanoscale Advances in Moisture Management for Natural Fiber Fabrics - Bill Stockton, Nano-Tex Inc.
Oxygen, Energy, Recovery: An Approach to Wellness through a Unique Fiber Design - Terry Turner, Wellman Inc.
Presented is a PET based fiber containing a proprietary blend of natural minerals purported to selectively modify light energy. Clinical studies using this fiber have demonstrated increases in transcutaneous oxygen perfusion (TcPO2). Anecdotal reports from users include reduced swelling, reduced pain, increased warmth, faster recovery from physical exertion, rapid healing from injury and improved sleep.
Nanostructured Metalloxides - Geoffrey Varga, Degussa Corp.
Nanostructured metal oxides produced in a controlled flame pyrolysis process exhibit a multitude of properties. Properties as flow improvement, dispersing aid or temperature insulation are controlled through particle size. The interaction of those particles in a matrix cause effects as thixotropy, reinforcement or stabilization of suspensions. Chemical modification of the particle surface alter compatibility to the incorporation matrix. The choice of the chemical element for the metal oxide gives access to properties as UV absorption, photo catalytic activity or conductivity. Combination and control of all parameters provides a toolbox which gives access to features ranging from improved polymer processing to polymer surface functionalization.
Surface Coatings Technologies - Mark Huggard, Luna Innovations Incorporated
Exposure to microbial pathogens on textiles and surfaces is a significant problem in many areas including hospitals and medical facilities, households, retirement facilities, food processing facilities and schools. Furthermore, current clothing worn by first responders and military personnel offers little to no protection from biological agents, as biological agents may remain active on the textile surface or even pass through the textile. Significant efforts are being directed toward development of polymer surfaces with permanent anti-microbial activity. The key feature of new antimicrobial technology is the incorporation of highly effective biocidal organic compounds with chemical hooks allowing attachment to a variety of polymeric materials. The persistent antimicrobial compounds enable coatings and textile surface treatments to resist microbial contamination.
Nanoscale Metal Antimicrobials in Textiles - Dennis Schneider, NanoHorizons
Textile antimicrobial technologies typically require users to manage a wide variety of attributes and issues: desired effectiveness, required durability, fabric design, dyeability, hand, direct material cost, manufacturing/materials handling issues, and environmental impact. This paper covers the impact of the latest advanced in nanoscale materials solutions in this decision calculus.
Nano Grooved Fibers Used in Self-Detoxifying Fabrics - Cheryl Gomes, Foster-Miller
Current military solutions for individual protection against chemical and biological weapons, such as the activated carbon based-JSLIST suit, have major shortcomings. Among the general difficulties presented by the need for Chemical and Biological Defense (CBD) are the variety of agents and threats that must be guarded against and the conflicting material requirements for individual protection. The current JSLIST suit has several major drawbacks:
•Limited life
•Limited moisture vapor permeability
•Need for decontamination and disposal
This presentation will discuss a material for CBD garments using an air permeable tri-laminate comprised of: an inner lining to make the suit comfortable against the body; a waterproof and air permeable treated expanded polytetrafluoroethylene (ePTFE) membrane to protect against aerosolized biological and liquid chemical agents while allowing for moisture vapor management; and an outer layer containing an active chemical decontaminating ingredient in a durable textile layer.
The outer layer includes a unique nano grooved or Capillary-Channeled Polymer (C-CP) fiber-encapsulated catalyst that can be spun into yarns and woven into a reactive nylon fabric. The surface area of the C-CP fiber could almost triple that of a standard round fiber; therefore, the reactivity of this fiber type could almost triple the decontamination potential.

Building Durable Antimicrobial Features into Sports Materials - Timothy H. Byers, Aegis Environments Inc.
Sports materials encompass a wide variety of applications and substrates, each with its own performance requirements for consumer satisfaction. From sporting goods to apparel, sporting fields to stadiums, and locker rooms to their linens, several unmet needs exist that a durable antimicrobial treatment can solve. Elimination of odor formation and protection of surfaces by silane quat technology is achieved via microbial control during use and after the game. Durable, multi-spectrum control of bacteria, mold, and algae is reviewed on emerging sporting applications and substrates, covering mode of action, application methods, test methods, and apparel comfort finish compatibilities.
