To further verify long-term stability, we next examined the in-situ emissivity tuning kinetics and cycle life of the ASPIRE device. process is faster than the reducing/dedoping process. The asymmetric redox kinetics align with previous findings , potentially due to higher activation energy in the dedoping state than in the doping state of PEDOT:PSS. Fig. ii) displays similar emissivity evolution data from the 439 th to 444 th cycle, where the IR emissivity tunability decreases to 13.1%, suggesting partial degradation of PEDOT:PSS or the PAM/LiCl hydrogel electrolyte.
