THE STUDY OF MORPHOLOGICAL STRUCTURES OF POLYIMIDE FILMS II
The morphological structures of polyimide films were studied by laser light scattering
X-ray diffraction
electron microscopy
infrared spectroscopy
cone light beam method and so on. There are obvious differences in orientation
nodules
chain-nodules
surface situation and spherulites for the PI films but no chemical differences. So various mechanical properties result from the different morphology. In addition
Azimuth Ωd can be used as a reference parameter to evaluate the orientation of the films.
