Effect of functionalized carbon nanotubes on properties of hot melt copolyamide. (Wpływ funkcjonalizowanych nanorurek węglowych na właściwości termotopliwego kopoliamidu)
Abstract
Hot melt copolyamide was mixed by the melt-blending process with 7 wt.% non-functionalized multi-walled carbon nanotubes and with amine modified multi-walled carbon nanotubes. The main goal of this work was to analyze the effect of functionalization of the properties of hot melt copolyamide. The rheological properties of the nanocomposites were examined by the dynamic oscillatory test using an oscillatory rheometer. Macrodispersion of both types of multi-walled carbon nanotubes within the copolyamide matrix was examined qualitatively by a light microscope and quantitatively using ImageJ Software. The thermal stability and characteristic temperatures such as the melting point and crystallization temperature were determined by thermogravimetric analysis and differential scanning calorimetry, respectively. It was found that the addition of 7 wt.% functionalized multi-walled carbon nanotubes increases the viscosity of copolyamide but to a lesser extent than in the case of non-functionalized multi-walled carbon nanotubes. Moreover, mixing copolyamide with amine functionalized multi-walled carbon nanotubes resulted in larger agglomerates which resulted in worse thermal stability than for non-modified multi-walled carbon nanotubes. Finally, the electrical conductivity measured by dielectric spectroscopy was lower in the case of nanocomposites with amine-functionalized multi-walled carbon nanotubes which indicates that the affinity to copolyamide was not improved by the amine groups.
