| Outline of Final Research Achievements |
The following three results were obtained: (1) surface force between sphere and plane in water was measured as a function of surface distance using a surface force apparatus with ultra-high resolution, (2) the effects of solvation and adsorbed molecules on the surface force for some material combinations were clarified by comparing with the measurement results in vacuum or air, and (3) numerical calculation program to simulate the surface force measurements using the surface force apparatus was developed.

| Academic Significance and Societal Importance of the Research Achievements |
固体表面近傍の液体分子の溶媒和による表面間力の測定，表面分子吸着層間の相互作用力測定結果には、様々な表面間力の成分が含まれているため、これまで定性的な議論にとどまっていた。本研究の成果は、この分野のこうした弱点を克服し、表面間力成分の詳細な特性解明のみならず、従来定性的な特性比較・評価にとどまっていた本研究分野をより定量的な段階へと押し上げるものである。すなわち、本研究成果は、学術的に大きな意義を持つと共に、研究分野自体の発展を促す重要な研究成果であると考えられる。
