We measure the crystalline temperature and melt temperature of PCL by DSC.then

the effect of crystallization time was studied by Polarized Optical Microscope (POM)

we find that:the change of crystallization time only change dimension of crystal

it did not influence the crystalline morphology. At last

Crystalline morphology of Poly(ε-caprolactone) was studied by AFM. At this paper

we mainly discussed the effect of substrate material、solvent and super cooling on crystalline morphology. It was found that:(1) the effect of substrate material on crystalline morphology is prominence

crystalline morphology on the silicon present club-structure

while on mica and on mica coated Carbon film on surface is dendrite structure.(2) the effect of solvent on crystalline morphology is prominence

it mainly depended on the vapor pressure. (3) the dendrites structure could be found at different temperatures

the width of dendrites increase with decreasing super cooling.
