Nanotube composites produced from single-walled carbon nanotubes and polycarbonate

Single-walled carbon nanotubes (SWCNTs) were dispersed in a polycarbonate (PC) matrix in a solution system and the composite was characterised by wide-angle X-ray diffraction technique, differential scanning calorimetry, a mechanical testing equipment and by FTIR-spectroscopy. The results showed a 58% increase in Young's modulus of PC with the addition of 0.5-5 wt% SWCNTs to the polymer matrix. Changes in the x-ray diffraction patterns, heats of melting etc. of the composite system were measured and are correlated to the changes in crystallinity and other molecular parameters.
