Abstract

We define a vector material as one can manipulate surroundings or circumstance of oneself. Especially, the interaction effect between surface charges and materials based on the electric force is called termed as electrovector effect. In this report, we demonstrated that fabrication and development of electrets which have electrovector effect. The electrets with hydroxyapatite (HAp) have the electrovector effect which increases the ability to promote bone regeneration (osteoanagenesis). In order to reveal the working and mechanism of electrovector effect on biomineralization in vivo, we study electrovector effect of crystal growth on the electret substrates. We found that surface charges on the substrates promoted precipitation of HAp in simulated body fluid (SBF), and influenced the morphology of calcite thin film growth on substrates with HAp and yittria stabilized zirconia (YSZ) .
