▎ 摘　　要

NOVELTY - Preparing functional film comprises (i) mixing polyvinylidene fluoride (PVDF), sheet-layer nanomaterial, and solvent, and stirring at room temperature for 5-24 hours, (ii) vacuumizing and heating at the same time, first heating to 40 degrees C, insulating for 1 hours, then heating to 100-150 degrees C, insulating for 1-24 hours, (iii) casting into a thin film and drying, and(iv) polarizing under low voltage. USE - The method is useful for preparing functional film. ADVANTAGE - The film: has high-voltage electrical property; and improves piezoelectric performance.
