Membrane composite polymer liquid crystal of Polymethyl Methacrylate with Mesogen Reactive Diacrylate (PMMA-RMDiacrylate) has been successfully synthesized. This research report of the synthesized and characterizations of PMMA-RMDiacrylate and analysis of capacitance and resistance. The purpose of this research is study of capacitance and resistance of membrane composite polymer PMMA-RMDiacrylate for membrane electrolyte in fuel cell system. Synthesized membrane composite polymer of PMMA-RMDiacrylate using methods of UV exposure to polymer solutions and addition of a Benzoyl Peroxide (BPO) initiator. Membrane composites polymer PMMA-RMDiacrylate were made with RMDIACRYLATE weight percent variations of 20%, 30%, and 40%. Membrane composite polymer PMMA-RMDiacrylate was characterized by FTIR that absorption peaks appear at wave numbers 2927 cm-1 indicating the -CH3 functional group, 1722 cm-1 indicating the C=O functional group, 1602 cm-1 indicating the presence of aromatic groups, 1248 cm-1 indicating the C-O-C group, 1060-1144 cm-1 indicating the C-O functional group. Texture and morphology analysis of membrane composite polymer of PMMA-RMDiacrylate showed effect of variations concentrations of RMDiacrylate. Analysis crystallinity by XRD results showed that the composite membrane polymer PMMA-RMDiacrylate is semicrystalline and sharp peaks appear as an indicator of phase crystallinity in the PMMA-RMDiacrylate membrane. Electrical properties of composite membrane of PMMA-RMDiacrylate using an LCR meter shows an increase in capacitance, resistance in sensors with 30% and 40% RMDiacrylate variations showed a decrease. The increasing concentration of RMDiacrylate in membrane composite polymer of PMMA-RMDiacrylate has good electrical properties. © Published under licence by IOP Publishing Ltd.
