| 英文摘要 | Poly(L-lactic acid) (PLLA) and PLLA/ultra high molecular weight poly (ethylene oxide) (PEO) blend were prepared by melt-mixing, respectively. The morphology and the stretching behavior as well as their dependence on stretching temperatures of PLLA and PLLA/PEO blend were studied with a combination of differential scanning calorimetry(DSC), scanning electron microscopy(SEM), and in-situ synchrotron wide-angle X-ray scattering(WAXS). The PLLA/PEO blend exhibited phase-separated morphology, with PEO particles as dispersed phase evenly distributed in PLLA matrix. The addition of PEO remarkably decreases the glass transition temperature(T-g) and increases the crystallization rate of PLLA. The fracture strain of PLLA/PEO blend increases drastically under uniaxial stretching at different temperatures of 25-60 degrees C. At lower stretching temperature (60 degrees C), the crystallization rate and fracture strain of PLLA/PEO blend increase. At higher stretching temperature (80 degrees C), the fracture stain of the blend is lower than that of the pure PLLA, while the crystallization rate is still higher than that of PLLA. |
