▎ 摘　　要

NOVELTY - A composition comprises graphene material(s) and metal(s). USE - Composition is used for forming article e.g. sheet, membrane and film for pressure sensor (all claimed) for monitoring wrist movement, squatting, walking, and delicate or simple finger touch. Can also be used for electrode for capacitor, catalysis, surface-enhanced Raman spectroscopy, smart material applications, biomaterial, chemical applications, electrical applications, imaging applications, touch screen panel, robotic systems and prosthetics. ADVANTAGE - The composition can be prepared by one-pot process, and provides film having high specific surface area, excellent electron transfer effect, electroconductivity, flexibility, durability, mechanical property and extensibility along two-dimensional plane. The pressure sensor having the film has excellent sensitivity to low pressure of 50 Pa. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) article; and (2) preparation of composition.
