摘要

Solid state polymer electrolyte attracts a great attention due to its thermal stability, no leakage, excellentflexibility, and good processability. There are many polymers have been investigated for electrochemicaldevice applications. This study aims to evaluate the efficiency of polymer electrolyte consists of PHA(Biologically recovered and purified poly (3-hydroxybutyrate-co-25% 3-hydroxyhexanoate) (P(3HBco-25% 3HHx)) and lithium perchlorate (LiClO4) for the first time. On the other hand, nanocrystallinecellulose (NCC) was also used as filling material, which was extracted from soda kenaf pulp via acidhydrolysis. Then extracted NCC was characterized by XRD, TEM, BET, 13C NMR, SEM, TEM, FTIR,and TGA. The results showed that the NCC extracted from soda kenaf pulp have high crystallinityindex. Finally, Polymer electrolyte was prepared by film casting method using NCC, biologicallyrecovered P(3HB-co-25% 3HHx) with different percentage of LiClO4 ((0, 10, 20, 30, and 40% (w/w)).Prepared thin films were analysed using cyclic voltammetry (CV) and electrochemical impedancespectroscopy (EIS). The results from CV and EIS analyses confirmed that the polymer electrolyteconsists of 40 % LiClO4 showed the highest conductivity of 1.56 × 10?4 S cm?1.c.
