The crystallographic orientation relationship between hydroxyapatite (HAp) nanocrystals and poly(acrylic acid) (PAA) graftpolymer-modified poly(ethylene terephthalate) (PET) substrate was studied using transmission electron microscopy (TEM). We investigated the microstructure of fabricated rod-like HAp nanocrystals and the interface of HAp/PET composite, where the HAp nanocrystals are bonded onto PAA graftpolymer-modified PET substrate. The selected-area electron diffraction (SAED) pattern of interface of the HAp/PET composite indicated that some low index planes in HAp prism plane tended to be contact plane with the PET substrate surface.
