Synthesis of Conducting Polyaniline with Photopolymerization Method and Characterization

Abstract Polymers as they are known as molecules formed by repetition of small molecules known as monomers, polymers that are often used cannot conduct electricity. Along with the development of the polymer era at this time can also conduct electricity known as conductive polymers. One of the conductive polymers that attracts attention is polyaniline. Synthesis of polyaniline conductive polymers is carried out with aniline monomers mixed with Ethylene Glycol Dimetacrylate (EGDMA) as Crosslinkers , and Dimethoxy phenylacetophenone (DMPP) as the initiator. In this reasearch, the polymerization processed with the photopolymerization method with a mixture of Aniline (mL), DMPP (0.1 g), and EGDMA (mL) polymerized with photopolymer. The polymers obtained were tested for electrical conductivity, the composition which showed optimum conductivity was in the ratio of aniline and EGDMA 1 : 1 with the electrical conductivity of 0.001462 Ohm.cm −1 . The conductivity measurement is done by using Four Point Probe (FPP) and other characterization measurements using FTIR (Fourier Transform Infrared) and TGA (Thermo-gravimetric Analysis).
