Abstract
The nanoindentation behavior of 3,3′,4,4′-biphenyltetracarboxylic acid dianhydride (BPDA)-based polyimide thin films was investigated. The crystallinity, chains, and the packing order were characterized with a prism coupler and wide angle x-ray diffraction (WAXD). The hardness of the thin films were also calculated from the curves of the nanoindentation load versus the displacement. The nanoindentation and birefringence results revealed that the mechanical properties of the films depended on the crystallinity, which was due to the chain order along the chain axis and the molecular packing order.
