  • Dispersions of carbon nanotubes in polymer matrices
    Publication number: 20060270777
    Abstract: Dispersions of carbon nanotubes exhibiting long term stability are based on a polymer matrix having moieties therein which are capable of a donor-acceptor complexation with carbon nanotubes. The carbon nanotubes are introduced into the polymer matrix and separated therein by standard means. Nanocomposites produced from these dispersions are useful in the fabrication of structures, e.g., lightweight aerospace structures.

  • Mechanically strong, thermally stable, and electrically conductive nanocomposite structure and method of fabricating same
    Publication number: 20060235136
    Abstract: A nanocomposite structure and method of fabricating same are provided. The nanocomposite structure is a polymer in an extruded shape with carbon nanotubes (CNTs) longitudinally disposed and dispersed in the extruded shape along a dimension thereof. The polymer is characteristically defined as having a viscosity of at least approximately 100,000 poise at a temperature of 200° C.

  • Electrospun electroactive polymers
    Publication number: 20060057377
    Abstract: Electroactive polymers are produced via electrospinning. The induction of electroactivity via electrospinning can be utilized with one or more soluble polymers with polarizable moieties. Suitable polymer classes include but are not limited to polyimides, polyamides, vinyl polymers, polyurethanes, polyureas, polythioureas, polyacrylates, polyesters, and biopolymers. Any one or more solvents sufficient to dissolve the one or more polymers of interest and make a spinnable solution can be utilized. The polymer can be electrospun into fiber and fibrous nonwoven mat. The electroactive polymer can be doped with inclusions, such as nanotubes, nanofibers, and piezoceramic powders for dielectric enhancement The availability of electroactive polymer fibers and fibrous nonwoven mat will enable many new applications for electroactive polymers.

  • Templated growth of carbon nanotubes
    Publication number: 20060013756
    Abstract: A method of growing carbon nanotubes uses a synthesized mesoporous silica template with approximately cylindrical pores being formed therein. The surfaces of the pores are coated with a carbon nanotube precursor, and the template with the surfaces of the pores so-coated is then heated until the carbon nanotube precursor in each pore is converted to a carbon nanotube.
