摘要： Polymer nanofibers, such as polyaniline nanofibers, with uniform diameters less than 500 nm can be made in bulk quantities through a facile aqueous and organic interfacial polymerization method at ambient conditions. The nanofibers have lengths varying from 500 nm to 10 μm and form interconnected networks in a thin film. Thin film nanofiber sensors can be made of the polyaniline nanofibers having superior performance in both sensitivity and time response to a variety of gas vapors including, acids, bases, redox active vapors, alcohols and volatile organic chemicals.

摘要： A new method for forming stable polyaniline nanofiber colloids uses electrostatic repulsion to maintain dispersion of the nanofibers and prevent aggregation during synthesis of the nanofibers. The colloidal suspensions are formed directly from the reactants in solution maintained at a pH of about 1.0 to about 4.0 and a temperature of about 10° C. to about 100° C. with minimal or no stirring. Also set forth are new methods for forming ultrathin films of polyaniline nanofibers via self-assembly.

摘要： The welding of certain polymeric nanofibers can be accomplished by exposure to an intense short burst of light, such as is provided by a camera flash, resulting in an instantaneous melting of the exposed fibers and a welding of the fibers where they are in contact. The preferred nanofibers are composed of conjugated, conducting polymers, and derivatives and polymer blends including such materials. Alternatively, the nanofibers can be composed of colored thermoplastic polymeric fibers or opaque polymers by proper selection of the frequency or frequency range and intensity (power) of the light source. The flash welding process can also be used to weld nanofibers which comprise a blend of polymeric materials where at least one of the materials in the blend used to form the nanofiber is a conductive, conjugated polymer or a suitable colored thermoplastic. Alternatively the material blend used to form the nanofibers may comprise a polymeric material containing a colored additive, which is not necessarily a polymer, for example carbon black, or a colored nano-particulate organic or inorganic material, dye or pigment.

摘要： Some embodiments of the invention include a method for preparing a carbon-containing membrane. The method includes preparing a carbon-containing solution and then washing and filtering the carbon-containing solution. The method further provides adding a volume of the washed and filtered carbon-containing solution to a receptacle that includes an aqueous solution. After a predetermined amount of time, the carbon-containing solution will equilibrate and form sheets of carbon-containing materials that float on a surface of the aqueous solution. The method further includes defining an aperture through at least a portion of a substrate and then inserting the substrate in the receptacle so that at least a portion of the carbon-containing sheets adhere to the substrate. In addition, the method further includes thermally treating the membrane to improve its molecular impermeability.
