Outline of Final Research Achievements |
Recently, the dispersion stability and fluidity of various functional nano-particles has been attracted and studied in industials and life science field. To improve the dispersion stability and fluidity of inorganic nano-particles, the use of ball-mill and surfactants were generally carried out until now. But, there are still remained some problems which are degradation performance of base materials and residual addition agents. In this study, we tried to modify the surface of various inorganic nano-particles such as TiO2, SnO2 and so on using fine surface fluorination skills. And we found the dispersion stability and fluidity of various inorganic materials by controlling the fluorination conditions with F2 gas.

Academic Significance and Societal Importance of the Research Achievements |
高い反応性をもつフッ素ガスと様々な無機ナノ粒子との表面反応メカニズムと分散安定性に関する報告例は殆どなく、非常に魅力な研究課題の一つである。また、精密フッ素処理法を用いることで、異なる結晶構造、異なる形状、異なる粒子サイズ、表面上の官能基の有無に関係なく、様々な無機ナノ粒子表面上の表面電荷を変化できることは、本研究の大きな特色・独創的な部分である。精密フッ素修飾技術によって高分散性や高安定性を有する様々な機能性ナノ粒子の作製が可能であれば、産業的・学術的にもその波及効果は非常に大きいと考えられる。また、前処理過程が必要なく、大量表面処理が可能となるので、新たな表面処理方法として期待できる。
