The Preparation Characteristic of Polyphenylenediamine -V$_2$O$_5$ Composite film

Polyphenylenediamine-V$_2$O$_5$ 복합 필름의 제막특성

A composite films were prepared by using Polyphenylenediamine(PPD) synthesized in our lab. and crystalline V$_2$O$_{5}$ in various mixture ratio for using positive active material of polymer film battery. The thermal stability of prepared composite film was carried out by using TGA. Electrical conductivity of composite film were also measured by using four-probe method in dry box. The thermal stability of prepared composite film is more than 35$0^{\circ}C$. The electrical conductivity of composite film increased and showed the highest value(about 23 S/cm) when doped at 0.4% LiCiO$_4$solution.n.
