Abstract: A carbon material-polymer strain sensitive film and its preparation method are disclosed. The carbon material-polymer strain sensitive film includes multiple layers of carbon sensitive films and multiple layers of polymer films, wherein the multiple layers of carbon sensitive films and the multiple layers of polymer films form a multi-layer composite film in sequence through a layer-by-layer assembly process. The preparation method includes steps of: cleaning, processing a hydrophilic treatment and processing a hydrophobic treatment on a rigid substrate in sequence; preparing a carbon material in dispersion solution and a polymer dispersion solution; through a layer-by-layer self-assembly process, growing the polymer and the carbon material in a form of layer-by-layer on the rigid substrate; transferring the composite film from the rigid substrate to a flexible substrate; and pasting two electrodes at two ends of the composite film and encapsulating with a flexible film.

Abstract: A three-layer self-healing flexible strain sensor includes: a self-healing sensitive layer, wherein a self-healing encapsulating layer is respectively placed on an upper surface and a lower surface of the self-healing sensitive layer. The self-healing sensitive layer comprises a doped carbon material or a conductive composite. The three self-healing layers of the self-healing strain sensor can quickly repair the internal and external damage caused by the layered structure in a short period of time after the external damage, and does not require external stimulation. The three-layer self-healing structure strain sensor is simple in preparation without using a repair agent, which can achieve rapid self-repair at the room temperature, and can be repeatedly repair. The three-layer self-healing structure increases the strength and modulus of the strain sensor as well as increases the ability of the strain sensor to resist external damage.
