A Study of Morphology in Polyethylene Filled with 3-Percent Carbon

Samples of polyethylene filled with 3-percent carbon were cooled from the melt at rates ranging from 104 to 10-1 C/min. The resulting degree of crystallinity, as measured from wide angle X-ray diffraction and density, was studied. Variations in the degree of crystallinity between 46 and 68% were observed. The role of morphology on the conduction properties of partially crystalline polymers is discussed.
