The conducting composites were prepared by solution blending of polyaniline (PANI) as a conducting polymer and polycarbonate (PC) as a matrix in chloroform. Also the composites film was prepared by solution casting method. The PANI was protonated with alkylbenzenesulfonic acids, such as camphorsulfonic acid (CSA) or dodecylbenzenesulfonic acid (DBSA). The electrical conductivity of composites prepared by solution casting was enhanced compared with that of compression molding. The electrical conductivity, tensile strength and morphology were observed as a function of the amount of protonating agent as well as PANI complex content. In general, as the PANI complex content was increased, the electrical conductivity increased. In the case of the composite film containing 25 wt% of PANI complex doped with DBSA, the electrical conductivity exhibited 2.18 S/cm.

Polycarbonate (PC)를 matrix로 사용하여 전도성 고분자인 polyaniline (PANI)과의 복합체를 블렌딩 방법에 의하여 제조하였다. 용매로는 chloroform을 사용하였으며 PANI는 전하수송을 가능하게 하고 유기용매에 잘 용해될 수 있도록 camphorsulfonic acid (CSA) 혹은 dodecylbenzenesulfonic acid (DBSA)와 같은 알킬 벤젠 술폰산으로 양성화시켰다. 또한, 전도성 복합체의 전기전도성은 압축성형이 아닌 solution casting 법에 의하여 향상시켰다. 아울러 양성화제 유무, PANI의 함량 또는 온도에 따라 전기전도도, 몰포로지 및 인장강도 등을 측정·분석하였다. PANI 착체의 함량이 많을수록 전기전도도는 증가하였으며 알킬사슬이 긴 DBSA로 양성화된 25 wt% PANI 착체의 전도성 복합체의 전기전도도는 3.18 S/cm까지 향상되었다
