Thermal properties of polycaprolactone/CNT nanocomposites

Addition of CNTs in the PCL (polycaprolactone) improves thermal and mechanical properties of PCL. That’s why in most cases CNTs are added to biodegradable PCL and such nanocomposite has a significant application for prosthetic leg. Investigated PCL/MWCNT nanocomposites were prepared by Brabender mixer as well as by dissolution in THF. The content of nanofiller was 1, 2 , 3 and 5 % wt. The infulence of MWCNT on the thermal stability and crystallinity was determined by simultaneous thermal analyzer (STA). Microstructure was performed by Field- Emission Scanning Electron Microscope (FE-SEM). Mechanical and Dynamic–mechanical properties were followed by Zwick Universal Mechanical Testing Machine and Dynamic-mechanical Analyzer (DMA). Results showed incresing crystallinity and better final properties with incresing MWCNT content in biodegradable PCL matrix.
