an important technique in the study of polymer molecular orientation structure
has been applied in the research of polymer/inorganic nanocomposites. The recent research progress of orientation of polymer/inorganic nanocomposites are reviewed here in combination with the authors’work. First
the definition of nanocomposite as well as the basic principle of infrared dichroism technique are introduced. Then
some examples of the application of infrared dichroism in the orientation studies of pure polymer are presented. Finally
the orientation studies of infrared dichroism in polymer/inorganic nanocomposites are mainly reviewed.
