摘　　要：Poly(ethylene terephthalate)(PET)/tin fluorophosphate glass(Pglass) hybrids were prepared via melt blending in the present paper,and the phase morphology,dynamic rheology,crystallization behavior,dynamic and static mechanical properties,and thermal stability of the hybrids have been investigated.Scanning electron microscopy(SEM) and transmission electron microscopy(TEM) showed the Pglass particles well dispersed in the PET matrix within a nanoscale.The results showed that the addition of Pglass induced some advantages on the properties of PET matrix,such as the decreasing of melt viscosity,increasing the isothermal crystallization rate and crystallinity,and improving the storage modulus and elasticity modulus.Poly（ethylene terephthalate）（PET）/tin fluorophosphate glass（Pglass） hybrids were prepared via melt blending in the present paper,and the phase morphology,dynamic rheology,crystallization behavior,dynamic and static mechanical properties,and thermal stability of the hybrids have been investigated.Scanning electron microscopy（SEM） and transmission electron microscopy（TEM） showed the Pglass particles well dispersed in the PET matrix within a nanoscale.The results showed that the addition of Pglass induced some advantages on the properties of PET matrix,such as the decreasing of melt viscosity,increasing the isothermal crystallization rate and crystallinity,and improving the storage modulus and elasticity modulus.
