Thesurfacemorphologyoffree-surfacePCLringedspheruliteswasinvestigatedbyusingatomicforcemicroscopy.ThespheruliteswereobtainedbycrystallizationofPCL/PVCblendsofdifferentcompositions.Itwasfoundthattheringedspheruliteexhibitedregularlyfluctuatingringsonitssurface.Comparedwiththebright-darkringpatternofthespheruliteunderapolarizingmicroscope,itwasprovedthattheopticalcharacteristicsoftheringedspheruliteunderpolarizingmicroscopecoincidedwithitssurfacecharacteristics.Thebrightringsinpolarizingmicrographsofthespherulitecoincidedwiththeconvexringsonitssurface,whilethedarkringscoincidedwiththeconcaverings.
