The invention provides a manufacturing method of a graphene-doped polymer temperature sensor, which comprises the following steps: A, preparing a GNPs / PDMS nano composite solution (a graphene-polydimethylsiloxane nano composite solution), and pouring the GNPs / PDMS nano composite solution into a template; B, carrying out bubble removal treatment on the GNPs / PDMS nano composite solution in the template, and heating and curing the template in a drying oven; C, taking out the baked template, cooling to room temperature, and taking out the film prepared in the template; and D, detecting the resistance values of the film at different temperatures, and obtaining the temperature sensor after the film data is detected to be qualified. In the invention, the preparation steps are simple, complex equipment is not needed, and the cost is low; the function that a temperature sensor with the measurement precision reaching 0.01 level can be obtained by using a small amount of graphene can be realized;according to the invention, the manufacturing of a matrix temperature sensor with good flexibility and repeatability is realized, and the temperature range which can be borne by the manufactured graphene-doped polymer temperature sensor is the temperature range which can be borne by PDMS.
Description
technical field [0001] The invention relates to the technical field of making temperature sensors, in particular to a method for making a graphene-doped polymer temperature sensor. Background technique [0002] A temperature sensor is a sensor that senses temperature and converts it into a usable output signal. This patent utilizes resistance sensing, and ordinary resistance sensing is that the resistance value of a metal changes with temperature. For different metals, every time the temperature changes by one degree, the resistance value changes differently, and the resistance value can be directly used as an output signal. There are two types of variation in resistance, which are positive temperature coefficient and negative temperature coefficient. The positive temperature coefficient means that the resistance value increases with the increase of temperature, and the resistance value decreases with the decrease of temperature; the negative temperature coefficient means ...
