Electrical and electromagnetic characteristics of poly (methyl methacrylate)/polyaniline PMMA/PANi conductive film / Helyati Abu Hassan Shaari ... [et al.]
In this study, a conductive film of poly (methyl methacrylate)/polyaniline (PMMA/PANi) was fabricated through a free radical copolymerization reaction using methyl methacrylate (MMA) and aniline monomers at different aniline-to-MMA ratios, namely, 1:1, 1:3, and 1:5. The PMMA/PANi copolymer films exh...
