Mixed phase solid polymer electrolytes based on poly(methylmethacrylate) systems

摘要: Abstract A composite polymer electrolyte PMMA–Li2SO4–DBP–ZrO2 was prepared by a solution casting technique; poly(methymethacrylate) (PMMA), dibuthylphalate (DBP). conductivity of 0.13×10−6 S cm−1 can be achieved at room temperature for the composition PMMA–Li2SO4–DBP (25–5–70 mol%), whereas it improves an order magnitude (7.5×10−6 S cm−1) upon dispersing fine particles ZrO2 (particle size = 21.5 μm) as inert fillers into above plasticized matrix. The role ceramic phase is to reduce melting and retard kinetics crystallization PMMA. This results in relaxation below PMMA, which appears characteristic these electrolytes.
