Periodic Surface-Ring Pattern Formation for Hydroxyapatite Thin Films Formed by Biomineralization-Inspired Processes
Surface
morphology is a key factor that might significantly influence
the properties of biomaterials. In this study, periodic surface-ring
structures have been constructed for calcium phosphate thin films
via biomineralization-inspired crystallization process. The patterned
octacalcium phosphate crystals have been obtained on poly(2-hydroxyethyl
methacrylate) (PHEMA) matrix in the presence of poly(acrylic acid)
(PAA). The patterned surface morphologies of the crystal thin films
could be tuned by the amount of PAA additives. In addition, the rapid
and topotactic transformation to hydroxyapatite (HAP) thin films with
surface-ring structures has also been achieved. This study may provide
new strategy toward the design of functional calcium phosphate-based
thin-film hybrids
