Multiwall Carbon Nanotube Reinforcement of Polyacrylonitrile Fibers

Aligning multiwall carbon nanotubes (MWNTs) with the direction of load is desirable for maximizing tensile reinforcement in composites. This has been accomplished by spinning composite fibers containing MWNTs[1]. The shear and elongational flow fields inherent to fiber processing cause the MWNTs to align with the fiber axis. Efficient stress transfer from the matrix to the MWNTs is also a cruci...

Photonics with multiwall carbon nanotube arrays.

We investigate the photonic properties of two-dimensional nanotube arrays for photon energies up to 40 eV and unveil the physics of two distinct applications: deep-UV photonic crystals and total visible absorbers. We find three main regimes: for small intertube spacing of 20-30 nm, we obtain strong Bragg scattering and photonic band gaps in the deep-UV range of 25 approximately 35 eV. For inter...

Hysteresis of sorption isotherm of multiwall carbon nanotube in paraxylene

The sorption isotherm of a multiwall carbon nanotube in paraxylene is investigated through a pressure induced infiltration experiment. The inner space of the carbon nanotubes can be occupied by liquid molecules when an external pressure is applied so that the energy barrier caused by the lyophobic surface is overcome. The infiltration–defiltration curve is highly hysteretic, and therefore a sig...
