Characterisation of crystalline poly(amide 6,12)fibers subjected to various γ-irradiation doses is presented. The specimens were analysed through their thermal, vibrational and morphological properties. All the experimental evidence points to the conclusion that chain scission may have occurred, forming low molecular weight species (oligomers) due to the degradation of the neat polymer chain. The thermal behaviour (fusion point and crystallinity) provides evidence that the oligomers formed act as plasticifing agents. The observed melting point depression of the irradiated poly(amide 6,12) samples is explained by Flory's theory [1]. The vibrational properties studied by Infrared spectroscopy (FT-IR) show the increase in crystallinity; the images obtained by atomic force microscopy (AFM) are also an evidence of the surface pattern modification by γ-irradiation. |
