| Tartalmi kivonat: | Castor-oil derivative polyamide 11 (PA11) is a promising candidate as a sustainable industrial material, where high-performance polymers are required. In this study the effect of a natural clay, muscovite mica, on thermal resistance of PA11 is investigated. Mica/PA11 composites were prepared by melt-compounding to achieve samples with filler contents of up to 5 wt% using two particle sizes. Enhanced thermal stability was evidenced by an enhanced temperature at maximum decomposition rate. Increments by an average of 13 °C were detected, which were higher in case of samples containing larger particles, while surface treatment changed the contribution of the decomposition pathways. Comparing these findings with the results on crystallinity ratio and water uptake, the increased thermal stability was attributed to the barrier effect of the lamellar impermeable fillers. |
