Abstract
To improve the mechanical properties of conductive polypyrrole film and to maintain its high electric conductivity, polypyrrole composite film with hostpolymer has been prepared by electrochemical method. The composite film was prepared in aqueous and nonaqueous systems with PVC(polyvinyl chloride) and PVA(polyvinyl alcohol) for hostpolymer. As a result of these electrochemical synthesis in H2O+PVA+TSA(p-toluene sulfonic acid)+ pyrrole system, we obtained conductive film of which mechanical properties were more excellent than that of the conductive film obtained in other systems. The conductivity of these films was about 50∼70 S/cm, and tensile strength was 45∼50 N/㎟, and elongation at break was 15∼18% . The characteristics of the film structure were examined and confirmed with FT-IR and SEM.

전해중합 Polypyrrole 필름의 우수한 전도성을 유지하며 역학적 물성을 향상시키기 위하여 전기화학적 방법으로 host polymer와 복합체를 구성하였다. host polymer로 PVA(polyvinyl alcohol)를 사용하여 수용액계와 비수용액계에서 복합차한 결과 H2O+PVA+TSA(P-toluene sulfonic acid) +Py(pyrrole) 계에서 전해중합했을 때 다른 계에서 얻어진 복합체를 필름 보다 역학적 물성이 우수한 전도성 복합체 필름을 얻었고 이때 필름의 전도도는 약 50∼70 S/cm, 인장강도는 45∼50N/㎟, 신도는 15∼18%였다 생성 필름의 구조 특성은 FT-IR과 SEM으로 조사 확인하였다.
