Abstract

The invention relates to a flexible temperature sensor based on a graphene nanometer wall and a preparing method thereof. The temperature sensor comprises polymer and a graphene nanometer wall body. The polymer is combined to the lower surface of the graphene nanometer wall body or embedded in the upper surface of the graphene nanometer wall body. The preparing method comprises the steps that after the graphene nanometer wall body made of the tubular CVD is transferred through the polymer transferring method, a graphene nanometer wall body / polymer double-layer structure is formed, the two ends of the graphene nanometer wall body are connected through a silver paste coating method to serve as an electrode with silver or other metal wires, spin coating can be carried out on upper layer of polymer, and a polymer / graphene nanometer wall / polymer three-layer structure is formed. The temperature sensor made of the graphene nanometer wall / polymer has the advantages of being simple in structure, convenient to machine, high in flexibility, light in weight, good in flexibility and biology compatibility and the like, and has very good application prospects in the fields of instruments, meters, photoelectric devices, flexible electronic skins and the like.

Description

technical field

[0001] The invention belongs to the field of sensors, and relates to a flexible temperature sensor based on a graphene nano-wall and a preparation method thereof. Background technique

[0002] A temperature sensor is a sensor that senses temperature and converts it into a usable output signal. According to the characteristics of sensor materials and electronic components, it can be divided into two types: thermal resistance type and thermocouple type. The thermal resistance temperature sensor is a sensor thermometer that uses the principle that the resistance value of a conductor or semiconductor changes with temperature. Thermal resistance temperature sensors are divided into two categories: metal thermal resistance and semiconductor thermistor. It will change the resistance value as the temperature rises. If it rises with the temperature and the resistance value also rises, it is called a positive resistivity. If it decreases with the temperature rise, it...
