Effects of induced surface charges generated by electrical poling on sodium dodecyl sulfate film formation on hydroxyapatite (HA) ceramic substrates from the aqueous solution. The HA ceramic disk cramped with a pair of Pt electrodes was polarized in air at a temperature ranging from 300 to 500°C for 1h in a dc electric field of 1 kVcm-1. 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 at 1500-1700 cm-1 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.
