摘      要：In this study,the rheological properties,crystallization and foaming behavior of poly(lactic acid)with polyamide 6 nanofibrils were examined with polyethylene glycol as a *** 6 particles were deformed into nanofibrils during *** the 10%polyamide 6 case,polyethylene glycol addition reduced the polyamide 6 fibril diameter from 365.53 to 254.63 nm,owing to the smaller polyamide 6 particle size and enhanced interface *** experiments revealed that the viscosity and storage modulus of the composites were increased,which was associated with the three-dimensional entangled network of polyamide 6 *** presence of higher aspect ratio polyamide 6 nanofibrils substantially enhanced the melt strength of the *** isothermal crystallization kinetics results suggested that the polyamide 6 nanofibrils and polyethylene glycol had a synergistic effect on accelerating poly(lactic acid)*** the polyethylene glycol,the crystallization half-time reduced from 103.6 to 62.2 *** foaming results indicated that owing to higher cell nucleation efficiency,the existence of polyamide 6 nanofibrils led to a higher cell density and lower expansion ***,the poly(lactic acid)/polyamide 6 foams exhibited a higher cell density and expansion ratio than that of the foams without polyethylene glycol.
