Development of Paper Actuators Based on Carbon-Nanotube-Composite Paper

Carbon Nanotube Paper-Based Electroanalytical Devices

Here, we report on carbon nanotube paper-based electroanalytical devices. A highly aligned-carbon nanotube (HA-CNT) array, grown using chemical vapor deposition (CVD), was processed to form bi-layered paper with an integrated cellulose-based Origami-chip as the electroanalytical device. We used an inverse-ordered fabrication method from a thick carbon nanotube (CNT) sheet to a thin CNT sheet. A...

Molecular ionization from carbon nanotube paper.

Ambient ionization is achieved by spraying from a carbon nanotube (CNT)-impregnated paper surface under the influence of small voltages (≥3 V). Organic molecules give simple high-quality mass spectra without fragmentation in the positive or negative ion modes. Conventional field ionization is ruled out, and it appears that field emission of microdroplets occurs. Microscopic examination of the C...

Electrically Activated Paper Actuators

Paper is an abundant, lightweight, and biodegradable material that has been used for centuries for printing, packaging, and absorbing liquids. Paper is a porous hydrophilic network of intertwined cellulose fi bers. [ 1 ] This network defi nes the mechanical and fl uidic properties of the material. [ 2 ] In recent years, paper has become increasingly interesting as a material in new applications...

Silicon/single-walled carbon nanotube composite paper as a flexible anode material for lithium ion batteries

Nanotube Composite Carbon Fibers

The mechanical properties of materials in small rod-shaped form are of considerable technological interest since, due to their shape and size, they can exhibit appreciably greater strength relative to corresponding macroscopic forms. For example, the mechanical strength of silicon carbide whiskers systematically increases with decreasing whisker diameter over the 100 to 1 micron range. This phe...
