title = "Mechanical crystallization properties and foaming behavior of teflon-reinforced poly(lactic acid) composites",
abstract = "In this study, poly(lactic acid) (PLA)/polytetrafluoroethylene (PTFE) composites containing different amounts of PTFE were prepared by melt blending. Multiple properties of the prepared composites were investigated including mechanical, crystallization, and foaming properties. Tensile test results indicated that the mechanical properties of the composite with PTFE showed significant reinforcement and toughening effects. The average elongation-At-break of the composite increased by 72% compared to pure PLA. Scanning electron microscopy (SEM) showed that the PTFE elongated into fibrils during blending and formed a physical network of entanglements in the melt. Differential scanning calorimetry (DSC) showed that PTFE had a significant nucleation effect and greatly increased the crystallinity of the PLA matrix. The injection molding foaming experiments revealed that adding 1 wt% PTFE had the most notable heterogeneous nucleation effect, with the cell size decreasing from 81.46 μm for neat PLA to 25.2 μm and the cell density increasing from 1.34×108 cells/cm3 to 2.53×109 cells/cm3.",
