[0027] Example 1
[0028] Weigh the spandex fiber, put it in the aniline monomer, soak it for 60s, take it out, then squeeze it uniformly, control the mass ratio of spandex fiber to the aniline monomer to 1:1, and place the extruded spandex fiber in a beaker. In 2h, the spandex fiber can fully absorb the aniline monomer. After 2h, the mass of the spandex fiber that has adsorbed the aniline monomer is weighed, and the original mass of the spandex fiber is subtracted to obtain the mass of the adsorbed aniline.
[0029] Use ammonium persulfate as the oxidant and hydrochloric acid as the doping acid to prepare the reaction solution. The concentration of ammonium persulfate in the reaction solution is 30 g / L, the concentration of hydrochloric acid is 1.0 mol / L, and the mass-volume ratio of An to the reaction solution is 1 g: 100 ml. Put the spandex fiber into the reaction solution to seal the beaker, and put the beaker into a 24°C gas bath constant temperature shaker for uniform shaki...
