Outline of Final Research Achievements |
Among many multi-purpose polymers, nylon is one of the most expectable polymers for development of ultra-high-modulus and ultra-high-strength materials. Theoretically predicted ultimate Young’s modulus is about 300 GPa. However, the strong intermolecular hydrogen bonds inhibit the translational motion of molecular chains along the draw direction, and no successful result had been reported so far. We found out a new phase transition immediately below the melting point, where the intermolecular hydrogen bonds are almost broken and the molecular chains experience the drastic thermal motion. It might be possible to draw the nylon sample at a high draw ratio in the high-temperature phase transition region. In fact, for nylon 66 and nylon1010, the drawing ratio was increased 2 times higher than the low temperature drawing and the Young’s modulus 3 times higher. Utilization of the sample with ultra-high molecular weight may lead to the successful production of ultra-drawn nylons.
