| abstract | PROBLEM TO BE SOLVED: To provide a film for a diaphragm capable of obtaining heat resistance of 150 ° C. or higher and improving durability. SOLUTION: A diaphragm film 2 made of polyetheretherketone resin and fullerene is laminated and adhered to an elastomer layer 4 via a primer 5 to form a laminated intermediate 3, which is molded to form a diaphragm. The mechanical properties of the film 2 are 90 N / mm 2 or more at the maximum tensile strength at 23 ° C, 100% or more at the tensile elongation at break, 80 N / mm 2 or more at the maximum tensile strength at 150 ° C, and the elongation at tensile break. It was set to 400% or more. Fullerene enters between the molecular chains of polyetheretherketone resin, and the heat resistance of the film 2 made of polyetheretherketone resin is improved by the interaction of van der Waals force acting between the molecular chains of fullerene and polyetheretherketone resin. It can be improved, and heat resistance of 150 ° C. or higher can be imparted to the film 2 for the vibrating plate. [Selection diagram] Fig. 2 |
