Polyacrylonitrile (PAN) fibers containing 10 wt.‐% single‐walled carbon nanotubes (SWNTs) exhibit a 100 % improvement in tensile modulus and reduced thermal shrinkage and polymer solubility. A 40 °C increase in glass transition temperature as compared to the control PAN fiber is also observed (see Figure). SWNT anisotropy has been observed using infrared spectroscopy.
