Abstract

Polyaniline (PANi) is a polymer that potentially has the electrical characteristic. In this report, we reported electrical conductivity and microwave characteristics of PANi that successfully synthesized through a chemical oxidative polymerization process using Ammonium Peroxidisulfate initiator of various concentrations (50 g/l, 100 g/l, and 200 g/l). The complete reaction of aniline polymerization was observed with the rise in temperature up to 42°C at concentration 200 g/l. It was accompanied by the increase in viscosity value indicating polymer chain formation. The structure of the PANi was confirmed by Fourier Transform Infra Red (FTIR) spectrophotometer. The electrical conductivity of PANi was generated through doping treatment using Perchloric acid (HClO4) as a doping agent. The results of four point probe evaluation of the dopant free PANi and HClO4 doped PANi at a room temperature showed a dramatic increase of the electrical conductivity of doped PANi. The result also showed that the electrical conductivity value of doped PANi decreased with an addition of the initiator concentration. Microwave absorption properties were characterized by measuring the permeability, permittivity and reflection loss (RL) at a frequency in the range 8-12.4 and 10-15 GHz using the Vector Network Analyzer (VNA).
