Various morphologies of poly(trimethylene terephthalate) (PTT) solution-cast thin films at different crystallization temperatures were investigated by polarized light microscopy (PLM),atomic force microscopy (AFM) and transmitted electron microscopy (TEM).In the range of 110-150 ℃,banded spherulite occurred and banding space gradually decreased along the radial direction from the primary nucleation site.Between 160 and 170 ℃,normal non-banded spherulite was found.Above 170 ℃,banded configuration occurred again.Lamellar growth direction of banded spherulite was determined to the crystal a-axis.
