Synthesis of PAMAM-GO as new nanofiller to enhance the crystallization properties of polylactic acid

The aim of this work is to study the effect of PAMAM-GO (fGO) on the crystallization properties of poly(lactic acid) (PLA). The results demonstrate that the isothermal crystallization rates are prominently enhanced with the addition of fGO. The spherulitic size of PLA in the composites are remarkably reduced in comparison with PLA, while crystallization half-time of PLA/fGO is almost decreased by 18.3%. Based on the results of this work, the use of fGO can serve as efficient heterogeneous nucleating agent for adjustable crystallization of PLA.
