Entering the Fourth Dimension - Manufacturing Responsive Liquid Crystal Elastomer Structures

The University of Texas at Dallas is seeking companies interested in commercializing an innovative method for fabricating Liquid Crystal Elastomer (LCE) structures that undergo reversible actuation in a wide variety of environments. This method uses direct-write additive manufacturing to locally-control the molecular orientation of LCEs, thereby programming...

Intelligent Textiles Prepared from Nanofiber Yarns and Polymer Fiber Actuators

While there has always been a desire for smart textiles, including fabrics which adapt depending on environmental stimuli, it has yet to be effectively accomplished due to the lack of suitable materials. These polymer fiber actuators have enabled the creation of fabrics that can reversibly change properties such as porosity, shape, color and texture....

Novel Solution for Selective Adsorption and Release of Gases Within Porous Materials

The potential for nanoporous materials, such as metal organic frameworks (MOFs), to be used effectively for energy storage and gas capture has been hindered by their relatively weak adsorption of gases. The primary approach for weak adsorption has been to develop metal centers that are more active. Such an approach often leads to complex synthesis procedures...

Sheath-Core Fibers for Superelastic Electronics, Sensors, and Muscles

Summary:From fitness trackers to smart clothing, wearables are in high demand. Researchers at UT Dallas have invented a new class of elastic wires that can be woven into clothing or made into super-stretchy charger cords. Lighter-than-air, electrically conductive sheets of tiny carbon nanotubes are wrapped around a long rubber core to create conducting...

Biscrolling Nanopowders and Carbon Nanotube Sheets into Fibers, Yarns and Textiles

Non-Confidential Description:The technology is the first known method to spin biscrolled fibers/yarns from nanopowder materials using carbon nanotube (CNT) sheets as the host. Nanopowder materials (nanoparticles, nanofibers) are loaded onto the CNT sheets to form bi-layered sheets, which are then scrolled into fibers. A key advantage of this technology...
