A flexible multifunctional sensing film structure and a preparation method thereof

Abstract

The application belongs to the field of strain sensors, and particularly relates to a flexible multifunctional sensing film structure and a preparation method thereof. The application takes two-dimensional material graphene as a core, designs and prepares an ultrathin flexible extensible structure and a sensing unit for sensing strain, near-infrared light and temperature, and integrates and designs different parameter sensing function units. A first layer is a rigid base layer with a polished surface; a second layer is a sacrifice layer; a third layer is a flexible base layer; a fourth layer is a rigid base material layer; a fifth layer is a two-dimensional material; a sixth layer is an electrode; and a seventh layer is a surface functionalization modification layer of a near-infrared light sensing unit. The application enhances the near-infrared light response sensitivity of graphene by surface functionalization modification of charge transfer complexes of graphene, and the overall design has flexibility, high sensitivity, independent sensing of multiple parameters and good environmental adaptability.
