Problems solved by technology

In some studies, they prepared carbon nanotubes into thin films (that is, carbon nanopaper) and combined them with some substrates, such as polyurethane sponge or cellulose paper, but they all have the disadvantage of poor tensile properties (pure sensors are described in related literature Only 0.5% of the total), therefore, in this invention patent, we have changed all the substrates and molding processes to overcome the above shortcomings

Abstract

The invention discloses a preparation method of a flexible sensor based on carbon nanometer paper, and belongs to the technical field of sensors. The preparation method comprises the steps that the carbon nanometer paper is taken, the carbon nanometer paper is cut according to the mold size, the cut carbon nanometer paper is put on a glass slide and is fixed, the cut carbon nanometer paper and a wire are bonded and fixed through an adhesive to be cured, and a carbon nanometer paper sensor is prepared; the curing temperature ranges from 50 DEG C to 150 DEG C, and the curing time ranges from 15min to 30 min; silicone rubber and a curing agent are mixed uniformly according to the proportion, and a silicone rubber solution is prepared; and the carbon nanometer paper sensor is soaked in the silicone rubber solution and is subjected to curing forming, and the flexible sensor based on the carbon nanometer paper is prepared. In the preparation process, the silicone rubber is soaked in the carbon nanometer paper, vacuum forming is combined, and agglomeration can be effectively avoided; and the prepared flexible sensor has good electric conductivity, and compared with metal sensors, the thickness can be greatly reduced.

Description

Technical field: [0001] The invention belongs to the technical field of sensors, and in particular relates to a flexible preparation method based on carbon nano paper. Background technique: [0002] In recent years, with the development of aeronautical technology, the environmental impacts of aeronautical composite structures have become more complex, especially the vibration caused by deformation is very serious, so it is very important to use sensors to monitor structural damage in real time. Since the advent of metal sensors in 1937, they have been widely used. However, due to their low sensing range and low flexibility, the use of conventional metal sensors is very limited. to important subjects. [0003] At present, the nanosensors produced in the industry mainly use carbon nanotubes as an important component. Carbon nanotubes have excellent electrical conductivity due to their large-scale large π bonds and significant conjugation effects. At present, some researches m...
