The presence of the nanofillers has a negligible effect on the crystallization temperature of PA 11 at low cooling rates. However, at rapid cooling conditions a distinct nucleating effect of the nanofillers is detected. The critical cooling rate to suppress crystallization increases from 600 K s–1 to about 1000 and 3000 K s–1 in nanocomposites containing sepiolite and montmorillonite, respectively. Regardless the cooling rate applied for solidification the melt, in the nanocomposites the crystallinity of PA 11 is 5 to 10 % higher than in neat PA 11, with the highest values obtained for the montmorillonite-containing system. The nucleating effect of the nanofillers onto the crystallization of the PA 11 is confirmed by analysis of the half-times of isothermal crystallization, and by analysis of the spherulitic superstructure. All measurements proved a saturation of the nucleation efficiency at a loading of the nanofiller of 2.5 m%.en© Springer-Verlag Berlin Heidelberg 2016.
