Detailed description of the invention:
Present invention is further illustrated below in conjunction with example.
Embodiment 1: be 5mg/cm by density3, aperture is that the graphene aerogel of 150 μm is placed in inert atmosphere according to table
1～table 3 shown in mode carry out high-temperature heat treatment, efficient pressure-sensitive Electric radiant Heating Film based on Graphene can be obtained after Temperature fall,
Then the both sides in Electric radiant Heating Film are respectively coated with PDMS insulating barrier, constitute Electric radiant Heating Film, at the two ends of Electric radiant Heating Film difference fixed electrode, electricity
Pole is connected with Graphene Electric radiant Heating Film；The electrocaloric effect recorded is shown in Table 1～table 3.
Table 1
Table 2
Table 3
From table 1 to table 3 it can be seen that the performance of Electric radiant Heating Film determines in terms of mainly having two, one material internal graphite oxide
Alkene chip architecture repairs coming off and the reparation of carbon conjugated structure under high temperature of situation, i.e. functional group.Its two, material internal three-dimensional takes
To the seriality of structure, the i.e. connectivity of internal sheets Rotating fields.The two common effect is to increase the performance of Graphene Electric radiant Heating Film.
In table 1, by compare A1 B1 C1 D1 the temperature of E1, A1 too low, be not enough to remove the official that major part is degradable
Can roll into a ball, cause gas in second step pyroprocess the most quickly to produce, at high temperature tearing sheet Rotating fields；E1 temperature is too high, produces
Angry body is too fast, can tear material internal structure in a large number, both can make deterioration in material properties.Have only in B1, C1, D1 temperature
Under, functional group can slowly and thoroughly remove, to ensure material property.By compare C1 F1 G1 H1, F1 heating rate too low,
Gas release is the slowest, it is impossible to make material internal form through hole；H1 temperature-rise period is too fast, and gas release is too fast, tears material
Material internal structure, is unfavorable for forming transmission channel.By compare C1 I1 J1 K1 L1 M1, I1 temperature retention time too short, it is impossible to protect
The degraded of the most of functional group of card；M1 insulating process is long, can absorb the tar inside stove, is unfavorable for the lifting of performance.J1、
K1, L1 just avoid both.
In table 2, by comparing A2 B2 C2 D2 E2, A2 heating rate is too low, has a strong impact on compressible performance and electric heating
Performance.E2 programming rate is too high, can tear Graphene interlayer structure so that graphene aerogel degradation.Have only B2, C2,
Under the programming rate of D2, just capable not only can ensure aerogel structure but also ensure the electric conductivity of Graphene.By compare C2 F2
G2 H2, F2 temperature too low so that stable functional group can not be sufficiently disengaged from, follow-up graphited during easily transition release
Venting body, destroys the internal structure of aeroge；By compare C2 I2 J2 K2 L2 too short, the stable official of M2, I2 temperature retention time
Can group can not fully come off；M2 overlong time, the easy tar adsorption of graphene aerogel film, it is unfavorable for carrying of Electric radiant Heating Film performance
Rise；And under the conditions of C2, J2, K2, both can ensure that fully coming off of stabilising functional group, it is avoided that again the puzzlement of tar.
In table 3, by compare A3 B3 C3 D3 E3, A3 heating rate too low, stabilising functional group come off the slowest, no
It is beneficial to the formation of graphene aerogel conductive network；E3 temperature-rise period is too fast, and gas release and high-temperature expansion are too fast, easily break
The structure of bad graphene aerogel.Only in the case of B3, C3, D3, the shape that the graphene aerogel of conductive network could be stable
Becoming, the structure on Graphene could be repaired slowly.By compare C3 F3 G3 H3 I3, F3 outlet temperature too low, Graphene
Structure repair is the most perfect, so various performance is the most very poor；Repairing of graphene-structured could be both ensured at a temperature of C3, G3, H3
Multiple, will not be vaporized again.By compare C3 J3 K3 L3 M3, J3 temperature retention time too low, graphene-structured can not fully be repaiied
Multiple, M3 temperature retention time is long, also can make to adsorb the tar in body of heater, affect the performance of Electric radiant Heating Film.
