Kennedy, James E. jkennedy@ait.ie Composite materials Crystallisation Differential scanning calorimetry (DSC) Electron microscopy (TEM) Polymers Link to publisher's homepage at http://www.elsevier.com/ With increased demands on catheter balloon functionality, there is an emphasis to blend new materials which can improve mechanical performance. Polymer nanocomposites were prepared by melt blending polyamide 11 (PA 11) with organically modified montmorillonite nanoclay. The effects of incorporating the nanoclay on the short-term mechanical properties of PA 11 were assessed using a design of experiments (DoEs) approach. X-ray diffraction (XRD), transmission electron microscopy (TEM), differential scanning calorimetry (DSC) and dynamic mechanical thermal analysis techniques (DMA) were used to characterise the morphology of the nanocomposites. Design of experiments studies revealed that the optimum nanocomposites properties can be achieved by carefully controlling the melt compounding parameters. XRD and TEM data proved that exfoliated clay morphologies existed within the matrix at low clay loading (2%). Whereas the interaction between the polymer matrix and nanoclay was quantified in the DMA spectra, showed a significant increase in storage modulus (up to 80%). The reinforcing effect of nanoclay within the PA 11 was further investigated using mechanical testing, where significant increases in the ultimate tensile strength and strain at break of reinforced tri-layer balloon tubing were observed. 2014-03-26T04:23:41Z 2014-03-26T04:23:41Z 2013-12 Article Materials Chemistry and Physics, vol. 143, Issue 1, 16 December 2013, Pages 336-348 0254-0584 http://www.sciencedirect.com/science/article/pii/S0254058413006755?via=ihub http://dspace.unimap.edu.my:80/dspace/handle/123456789/33135 en Elsevier B.V. |
