Polymer confinement effects in aligned carbon nanotubes arrays.
We present experimental and theoretical studies on the infiltration of polymers (polystyrene (PS), polymethylmethacrylate (PMMA)) into the free interstices of 3D aligned carbon nanotube arrays. The 3D aligned CNT structures were prepared by a template assisted non catalytic CVD approach. The infiltrated CNT/polymer composites were characterized by microscopic techniques such as infra-red and Raman spectroscopy. Small angle X-ray scattering (SAXS) has been employed to study the structural evolution and polymer confinement after the polymers are infiltrated in the aligned arrays of CNTs. A theoretical model has been used to understand and predict possible confinement effects of these polymers within the aligned CNT arrays, using self-consistent field theory (SCFT) and Monte-Carlo simulations based on the bond-fluctuation model.
