室温付近でも高いAg+イオン伝導性を示すAgI-Ag2O-B2O3ガラスを先鋭化して電界印加することで、室温かつ大気圧雰囲気においてもAg+イオン放出を確認しました。Ag+イオン放出寿命を電気化学水晶振動子微量天秤による電流値と振動数変化から議論しています。またAg+イオン照射後のガラス基板にはより多数のHeLa細胞が付着することを明らかにしました。兵庫県立大学との共同研究成果です。

SiO2(シリカ)はSiが4つの酸素で囲まれていますが、4つのうち一つをフェニル基に置き換えたものがフェニルシルセスキオキサン(PSQ)と呼ばれます。このPSQ粒子はゾル-ゲル法によって合成でき、粒子をガラス転移温度以上で加熱プレスすることで透明なバルク体に転移し、また絶縁性も比較的高いです。粒子→バルク転移時の変形挙動をin-situ解析したところ、粒子間にボイドが存在する場合は粘弾性挙動を示すのに対して、ボイドフリーのものは弾性変形すること、またボイドフリーの方がより高い絶縁耐圧を示すことを実験的に明らかにしました。

成形性に優れるAg+イオン伝導性ガラスを溶融法で作製して、その先端を先鋭化して真空条件で高電圧を印加することで、ガラス先端からのAg+イオン放出を確認しました。イオン電流と電圧の関係はショットキープロットでよい直線性が見られ、Ag+イオン放出は熱電子放出と同じショットキーモデルで表されることが明らかとなりました。
