Abstract

Atomic force microscopy (AFM) has been used to image the internal structure of broken surfaces of a starch-zein thermoplastic polymer that had been previously pressure-formed into tensile bars. Analysis of the AFM data reveals that the surface of starch-zein polymer consists of a complex mixture of crystalline and amorphous domains. AFM analysis of the crystalline domains of a freshly broken tensile bar surface show highly ordered skein-like arrays. At higher magnifications helical arrays suggestive of a double helix structure are present.
