Abstract
It is known that organic acids doped Polypyrrole (PPy) will conduct electricity, and the electrical characteristics of the polymer is presented in this paper. The PPy is deposited on a glass substrate using a spin coater, resulted in a thin film with of 0.0823 μm thickness. The I/V characteristics of the PPy thin film were measured using two-point and four-point probe at room temperature. The finding shows that the I/V characteristic is nonlinear. Comparison between these two methods is further explored, and statistically it shows that there is no mean difference between the two methods. Hence, it helps in designing future experiment to measure I/V characteristics at elevated temperature.
