Development and characterization of CFRP using a polyaniline-based conductive thermoset matrix

In this work, we describe the development of carbon fiber reinforced plastics (CFRP) using a polyaniline (PANI)-based electrically conductive thermoset matrix to enhance its electrical properties. The conductive thermosetting resin uses dodecylbenzenesulfonic acid (DBSA) and p-toluenesulfonic acid (PTSA) as dopants and divinylvenzene (DVB) as the crosslinking polymer. The thermal and electrical properties of the PANI-based thermosetting resin are characterized as part of the work. The developed resin is utilized to fabricate CFRP by a prepreg-based hot press method. This paper reports on the electrical properties of the fabricated CFRPs, which exhibit excellent electrical conductivity in the thickness direction. Finally, the electromagnetic shielding properties of the developed CFRP are demonstrated and compared to traditional CFRP.
