    摘要： Methods are provided for mechanically chopping nanotubes and other nanoscale fibrous materials. The method includes forming a macroscale article which include the nanoscale fibers, and then mechanically cutting the macroscale article into a finely divided form. In one embodiment, these steps are repeated. The nanoscale fibers may be carbon nanotubes, which optionally are aligned in the macroscale article. The macroscale article may be in the form of or include one or more buckypapers. In one embodiment, the macroscale article further includes a solid matrix material in which the nanoscale fibers are contained or dispersed. The forming step can include making a suspension of nanoscale fibers dispersed in a liquid medium and then solidifying the liquid medium to form the macroscale article. After the mechanical cutting step, the medium can be dissolved or melted to enable separation of the chopped nanoscale fibers from the medium.

    摘要： Methods are provided for functionalizing a macroscopic film comprised of nanoscale fibers by controlled irradiation. The methods may include the steps of (a) providing a nanoscale fiber film material comprising a plurality of nanoscale fibers (which may include single wall nanotubes, multi-wall nanotubes, carbon nanofibers, or a combination thereof); and (b) irradiating the nanoscale fiber film material with a controlled amount of radiation in the open air or in a controlled atmosphere. The step of irradiating the nanoscale fiber film material is effective to functionalize the plurality of nanoscale fibers. Irradiated nanoscale fiber films are also provided having improved mechanical and electrical conducting properties.

    摘要： Methods and devices are provided for the continuous production of a network of nanotubes or other nanoscale fibers. The method includes making a suspension of nanoscale fibers dispersed in a liquid medium, optionally with surfactant and/or sonication, and filtering the suspension by moving a filter membrane through the suspension, such that the nanoscale fibers are deposited directly on the filter membrane as the fluid medium flows through the filter membrane, thereby forming a continuous membrane of the nanoscale fibers. The deposition of the nanoscale fibers can occur when and where the filter membrane moves into contact with a static, porous filter element or a dynamic, porous filter element. The filtering can be conducted within a magnetic field effective to align the nanoscale fibers, and/or with the aid of vacuum to pull water through the filter membrane, applied pressure to press water though the filter membrane, or a combination thereof.
