Preparation and Characterization of Epoxidized-30% Poly(methyl methacrylate)-grafted Natural Rubber Polymer Electrolyte

Abstract

In this study, a freestanding thin film composed of lithium triflate (LiTf) salt (30-40 wt.%) and epoxidized-30% poly (methyl methacrylate)-grafted natural rubber (EMG30) (50, 54.6, 62.3 mol %) were prepared by a solvent cast technique. The EMG30 were found to increase the ionic conductivity of EMG30-LiTf by one order of magnitude compared to MG30-LiTf. The highest ionic conductivity achieved was 5.584 x10-3Scm-1at room temperature when 40 wt.% of LiTf salts were introduced into 62.3 mol % EMG30. The ionic conduction mechanisms in EMG30-LiTf electrolytes obey Arrhenius rule in which the ion transport in these materials is thermally assisted.

Electrochemical Properties of Polymer Electrolytes Treated With 6ppd on 30% Poly(methyl Methacrylate) Grafted Natural Rubber

“…Until today research has been geared to enhance the electrolytes properties of MNR particularly to obtain high ionic conductivity at room temperature with better mechanical properties. Various MNR has been used such as by using epoxidized natural rubber (ENR-25 and ENR-50) [2][3][4][5] and methyl grafted natural rubber (MG49 and MG30) [6][7][8][9][10] as a polymer host to produce PEs. The introduction of metal oxide inorganic filler such as TiO 2 , SiO 2 and Al 2 O 3 also was reported successfully enhanced the mechanical properties and improve ionic conductivity at room temperature [11][12][13].…”

Effect of Phenylene Diamine Antioxidant on Physico-Chemical Properties of Methyl Grafted Natural Rubber Polymer Electrolytes

“…30% poly(methyl-methacrylate) (PMMA) grafted natural rubber (MG30) is a bright candidate to be used as polymer electrolytes since it was introduced many years ago [7][8][9][10]. It possesses a high affinity of carbonyl polar functional group from PMMA side chain which offered a complexation site with lithium salt.…”
