Raw material eggshells were dried in an oven and blended into a powder. 1-methyl-2-pyrrolidinone was added to PANI powder to produce a PANI solution and activated charcoal powder was then added. The solution was placed into a heating mantle with a controlled temperature until a uniform solution was produced. The resultant conductive polymer was then analysed by scanning electron microscopy SEM Fourier transform infrared FTIR Brunauer Emmett and Teller BET and X-ray diffraction XRD . The results of these analyses show that PANI-ESP did not undergo a chemical structural change. The only interaction that occurred was between the filler reinforced with carbon black CB and the matrix. The structure of the composite was a face centred cubic FCC structure with an average lattice parameter of nm. The surface morphology of the composites shows that agglomeration occurred to complete the connection of the conductive path thus improving the conductivity behaviour. The conductivity of the PANI-ESP composite was also studied and measured in situ during the mixing process.

Bahan mentah iaitu kulit telur telah dikeringkan di dalam ketuhar dan dikisar sehingga menjadi serbuk. 1-metil-2-pyrrolidinone ditambah ke dalam serbuk PANI untuk menghasilkan larutan PANI dan seterusnya serbuk arang yang diaktifkan ditambah. Larutan tersebut diletakkan dalam mantel pemanasan dengan suhu terkawal sehingga larutan yang sekata dihasilkan. Polimer .
