Electrospun Hybrid Composite Poly(L-Lactide) Nanofibers Incorporating POSS-Modified Multiwalled Carbon Nanotubes

摘要

We report the preparation of electrospun poly(L-lactide) (PLA) nanofibers incorporating polyhedraloligosilsesquioxane (POSS)-modified MWNTs. FT-IR and transmission electron microscopy (TEM) analysis confirms the existence of POSS macromers bonded to the multiwalled carbon nanotubes (MWNTs) as an extra phase. The dispersion of POSS-modified MWNTs in the PLA hybrid nanofibers is evaluated by TEM analysis. The thermal and microstructure properties of the PLA hybrid nanofibers with POSS-modified MWNTs were investigated by Thermogravimetric analysis (TGA) and Wide-angle X-ray diffraction (WAXD), respectively.
