Early Degradation

Lithium iodide/epoxidized natural rubber (LiI/ENR-50) and potassium iodide/epoxized natural rubber (KI/ENR-50) polymer electrolytes (PEs) were prepared via solvent casting. The PEs were characterized using FTIR, DSC and SEM techniques. The observed IR bands shift and the increased in Tg value in both PEs suggest that some interactions may have occurred between the ENR-50 and the respective cations. The appearance of new C=O band at ~1720 cm-1 coupled with the intensification of the OH band in KI/ENR-50 was due to the early degradation of ENR-50 promoted by KI. The kinetic analyses of the thermal degradation of neat ENR-50 and the respective PEs were studied using TG at five different heating rates. Kissinger was employed to obtain the degradation activation energy (Ed). LiI/ENR-50 shows higher Ed as compared to pristine ENR-50 and the Ed increases with increasing LiI loading. The Ed of KI/ENR-50 was observed to be higher than that of pristine ENR-50 when KI is 30 wt %. Thus, LiI retards the degradation of ENR-50 regardless of the wt % LiI added. KI, however, can either retard or catalyzed the degradation of ENR-50 depending on the salt loading.
