Embodiment
A kind of manufacture craft of solid-state aluminum electrolytic capacitor, includes the synthesis of PEDT films, the synthesis of the PEDT films
Comprise the following steps, 1）EDT monomers or EDOT monomers are added among solvent, and it is uniform with supersonic oscillations；2）Will
The mixed liquor of toluene sulfonic acide iron n-butanol is added to step 1）In solution in polymerize at a temperature of 5-35 degrees Celsius
Reaction；3）By step 2）Solution after polymerization volatilizees solvent at a temperature of 40-200 degrees Celsius；4）By step 3）Obtain
Film is made in slurries；5）By step 4）Obtained film is put into toluenesulfonic acid solution to react 15 minutes and taken out, and cleans up
Dried afterwards at a temperature of 130 degrees Celsius.
In the present embodiment, the concentration of toluenesulfonic acid is 14%.Found by multiple contrast tests, when the concentration of toluenesulfonic acid
For 14% when, the resistivity of PEDT films is minimum, as shown in Figure 1.
In the present embodiment, the proportioning of EDT monomers or EDOT monomers and toluene sulfonic acide iron n-butanol is 1:2-1:8.One
As when making capacitor, it is necessary to carry out the synthesis of multiple PEDT films to reach enough thickness, it is general to carry out 5-10 times,
