ケイ酸塩物質は地殻を構成する鉱物の大部分を占め，地球上で最も産出量が多い．加えて毒性もない．ケイ酸塩物質は一般に絶縁体に分類される．つまりケイ酸塩物質そのものに電流は流れない．資源的に安定で，かつ環境負荷のないケイ酸塩物質が伝導特性を持つようになれば環境・エネルギー分野の観点から意義がある．本研究では，ケイ酸塩鉱物中に多量に含まれる二次元形状のナノ空間，およびナノ空間内部で強く凝集する特異な水分子ネットワークに着目する．メカノケミカル反応により二次元形状ナノ空間を一次元異方性を有するナノ空間に改質し，一次元方向に空間制約を受けた準一次元アイスを構築する．平行して高い反応断面積で水分子解離を進行させ，効率的なプロトン生成を行う．さらにナノ空間近傍に局所生成する負電荷にプロトンを弱局在させ，空間内部への閉じ込めを行う．上記を同時に発現させることにより，無加湿・常温環境下で超プロトン伝導の発現を目指す．初年度は，ベースとなる試料としてケイ酸塩鉱物である合成サポナイトナノ粒子を採用した．当該試料には，サポナイトの基本ユニットである二次元ナノシート層間のナトリウムイオンに物理吸着した吸着水が多量に存在していることが熱重量示差熱同時測定でわかった．メカノケミカル反応を推進するための水分子ネットワークが十分に得られることが示唆された．湿式条件下で遊星型ボールミル等を用いたメカノケミカル反応により，サポナイトを構成するSiO4四面体の剥離，細分化が示唆された．ポジトロニウム分光実験によるナノ空間計測からは，二次元形状ナノ空間が一次元異方性を有するナノ空間に改質されていることが示唆された．

Most of the environmental pollution is due to the fact that the earth accounts for the majority of the pollution, and the highest output on the earth is very high. It is not only toxic but also toxic, and it is classified into several categories, such as electricity, electricity, water, electricity, water, electricity, and so on. In this study, a large amount of carbon dioxide in the environment contains a large amount of carbon dioxide in a two-dimensional shape. In this study, a large amount of sodium chloride in the environment is found to contain two-dimensional shape. The interior of the space is strongly agglutinated, the molecules of water are strongly agglutinated, and the two-dimensional shape of the two-dimensional shape of the space is strongly agglutinated. The one-dimensional property of the space is affected by the one-dimensional space modification, and the one-dimensional space system is subject to the standard one-dimensional one. The separation of water molecules in parallel high altitude reaction cross-section is carried out. The environmental pollution rate is generated. The thermal load generated by the space near the station is in the middle of the air, while the internal one in the space is in operation. At the same time, it was recorded that the environmental pollution occurred at the same time, and the target was observed in the humidified ambient temperature environment. This is the first time that the compound has been synthesized and the particles have been used. When the material is not used There is a difference between the physical absorption of water in the air and the amount of water in the ambient air. The weight difference of the temperature is measured at the same time. The molecular weight of the water is very good. The wet condition is very good. In the following words, such as the star, the stars, etc. The system is separated into a SiO4 tetrahedron, and the differentiation indicates that it can be separated into a tetrahedron, and that the two-dimensional shape, the space dimension, the space, and the space.
