摘要: Abstract The polyvinylidene fluoride (PVDF) drew great attention over time amongst the hydrocarbon polymer membranes because of its high C–F chemical bond strength. In this work is to increase proton conductivity PVDF by doping phosphonated graphene oxide structure and investigate improvement membrane. Different amounts additive (0.5%, 1% 1.5% w/w) were doped on purpose synthesizing exchange composite membranes. Characterization tests, i.e, water uptake, swelling properties, ion capacity, synthesized investigated. electrochemical impedance analysis results vary between 0.0224 S cm-1 for 0.5% (PVDF/0.5PGO) 0.0867 PVDF/1.5GO power density values PVDF/1.5PGO PVDF/0.5GO are 48 mW cm−2 28 mW cm−2 at 0.6 V 100% relative humidity 80 °C. experimental demonstrate importance into
