摘要:
The optical material in accordance with the present invention contains a specific phosphonate monoester compound such as monoethyl 3-methoxybutyl phosphonate, and a metal ion such as a copper ion or rare-earth metal ion. They may be contained in a solvent or resin. The use of such a specific phosphonate monoester compound improves the compatibility with a resin, whereby the metal ion can favorably be dispersed into the resin. Consequently, spectral characteristics can be improved when the optical member is formed into a resin-made optical member.
摘要:
A binder solution for providing an electrode suitable for use in non-aqueous-type electrochemical devices, such as a battery and an electric double layer capacitor, is formed by dissolving a vinylidene fluoride polymer having an inherent viscosity (and thus a polymerization degree) higher than a conventional level in an organic solvent. An electrode-forming composition is formed by dispersing powdery electrode material in the binder solution and is applied onto an electroconductive substrate while avoiding the gelation of the polymer, followed by drying, to form a composite electrode layer, which retains the powdery electrode material at a smaller amount of vinylidene fluoride polymer than a conventional level and is well resistant to a non-aqueous electrolytic solution.
