摘要：

Strong polymer-MWCNT interactions in millimeter-high MWCNT/poly(vinyl alcohol) composite mats of vertically aligned tubes are reported. SEM and TEM imaging revealed extensive polymer sheathing to have occurred homogeneously over the nanotubes in the mats without influencing their morphology, alignment or physical characteristics. A 7- to 10-fold increase in the apparent nanotube diameter due to poly(vinyl alcohol) sheathing was measured. Thermogravimetric analysis showed that the composite mats were thermally more stable than the pure polymer. Differential scanning calorimetry results were compatible with a crystallinity increase of the polymer phase due to the presence of CNTs of the order of 18%. Potential applications of the produced composites include filters, components for sandwich panels and sensors. (C) 2012 Elsevier Ltd. All rights reserved.
