Abstract

The characterization of biopolymer-based solid polymer electrolytes (SPEs) has been carried out in this present work. Cellulose derivative was chosen due to its superior physical attributes. In this work, NH4Br-doped glycerol plasticized carboxyl methylcellulose-based SPEs were successfully prepared via the solution casting method. The conductivity and dielectric properties of the prepared films were investigated using the impedance analysis which presented ~1.91×10-3 Scm-1 (with addition of 6 wt% of glycerol). In addition, the studied SPE system shows a non-Debye behaviour without a single relaxation time. The findings of the research indicate that the complexes of NH4Br and glycerol in the cellulose derivative influence the ionic conductivity and dielectric properties of the SPE system.

Bahasa Abstract

Kajian Sifat Dialektik dari Gliserol Turunan Selulosa-NH4Br- Berdasarkan Sistem SPEs. Perkembangan elektrolit polimer pepejal (SPEs) berdasarkan bahan bio-polimer telah dilakukan dalam kajian sekarang ini. Bio-polimer dari turunan selulosa dipilih karena sifatnya yang unggul. Dalam karya sekarang ini, SPEs berdasarkan karboksil metilselulosa didopkan dengan NH4Br dan terplastikkan dengan gliserol telah berhasil disiapkan melalui metode tebaran larutan. Sifat unggul film telah diselidiki dalam terma konduktivitas mereka dan juga sifat dielektrik menggunakan teknik impedansi. Nilai ionik tertinggi untuk nilai konduktivitas yang ditemui ialah 1,91 × 10-3 S cm-1 ketika 6 wt.% gliserol ditambahkan. Sifat dilektrik dari sistem SPEs menunjukkan tren yang signifikan di mana sistem ini secara tepatnya dapat disebut perilaku non-Debye tanpa waktu relaksasi tunggal. Interaksi dari NH4Br dan gliserol dalam turunan selulosa telah menunjukkan bahawa ianya mempengaruhi konduktivitas ionik dan sifat dielektrik dalam sistem SPEs.
