摘要

Carbon nanotubes (CNTs) have been studied extensively due to their exceptional properties since 19911. CNTs have high modulus and high strength (~1 TPa and ~36 GPa, respectively)2,3. Recent studies suggest that polyacrylonitrile (PAN)/CNT composites are expected to be quite important4-11. PAN/CNT films and fibers4,9,11 with significant property improvements are being processed, indicating good interaction between PAN and CNTs, and the preliminary stabilization and carbonization studies on PAN/CNT composites also show promising results for processing next generation carbon fiber10. While CNT orientation as high as 0.98 has been achieved in the composite fiber11, theoretical studies suggest that in order to achieve the predicted modulus from CNTs, orientation factor approaching one is needed. To achieve ultra high SWNT orientation, PAN/SWNT composite fibers have been processed using gel spinning where draw ratios greater than 50 can be achieved. The results show nearly ideal SWNT orientation and nearly ideal modulus translation in the composite fiber. The properties of composite fibers spun by conventional dry-jet-wet spinning are also presented for a comparison.
