Table 2 table of data on film layer condition of electric heating films obtained in examples 1 to 5 and comparative examples 1 and 2
The heating efficiency of the electric heating films with the area of 100mm multiplied by 100mm obtained in the examples 1 to 5 and the comparative examples 1 and 2 is respectively tested in different pressure states;
the method and the calculation mode for testing the heating efficiency are as follows:
connecting metal electrodes at two ends of the prepared electrothermal film, applying 15V voltage on the electrodes by using a direct current power supply, and heating for a period of time until the temperature is stable. According to the law of conservation of energy, when the temperature of heating is increased to the maximum value, the heating quantity of the electrothermal film is equal to the energy radiated outwards, so the heating efficiency
h＝IV0/[(Tm-T0)*S]；
Wherein h is the film heating efficiency (W/(. degree. C. mm)2))；
I is the current (A) when the temperature is stable;
V0voltage (V) at which temperature is stable;
Tmthe highest temperature;
T0the ambient temperature is 25 ℃ in the invention;
the change in the area S is ignored in the calculation of the heat generation efficiency.
Table 3 heating efficiency of the electric heating films obtained in examples 1 to 5 without being pressed
Table 4 heating efficiency of the electric heating films obtained in examples 1 to 5 at 200Pa
TABLE 5 heating efficiency of the electrothermal films obtained in examples 1 to 5 at 400Pa
TABLE 6 heating efficiency of the electric heating films obtained in examples 1 to 5 at 600Pa
TABLE 7 heating efficiency of the electric heating films obtained in examples 1 to 5 at 800Pa
It can be known from the data in tables 1 to 7 that the heating efficiency of the electrothermal film layer obtained by the present invention gradually increases to saturation along with the change of the pressure condition, and the heating temperature also gradually increases. Compared with comparative examples 1 and 2, in examples 1 to 5, after being compressed, the distance of the graphene and/or the multi-walled carbon nanotubes in the vertical direction is reduced, and the graphene and/or the multi-walled carbon nanotubes relatively slide in the horizontal direction, wherein the silica/lignin composite particles not only serve as particle conductive agents to increase the formation and conduction of a three-dimensional conductive network, but also serve as lubricants for the relative sliding of the graphene and/or the multi-walled carbon nanotubes in the horizontal direction, so that the relative sliding is facilitated, and the electrothermal film is sensitive to pressure. Further comparing example 1 with examples 2 to 4, it can be seen that the guiding protrusions of the oriented elastic film of the base layer enable the graphene and the multi-walled carbon nanotubes to be stacked in an inclined and ordered manner, so as to improve the internal ordering of the three-dimensional conductive network.
