Control of self-assembled layers on electrically poled hydroxyapatite ceramics

Abstract

Effects of induced surface charges generated by electrical poling on SDS film formation on hydroxyapatite (HA) ceramic substrates from the aqueous solution. The films on the non-poled HA ceramics was significantly thicker than those on the poled ceramics, regardless of the charge polarity. The characteristic absorption band was detected in the films on the negatively charged HA surfaces by FT-IR spectroscopy. It was revealed that the induced charges affected the formation rate and the structures of SDS films.
