Effect of polyaniline on resistivity-temperature behavior of polyurethane / carbon black composite |
| 초록 |
To avoid the negative temperature coefficient (NTC) effect in the polyurethane (PU) / carbon black (CB) composite, the homogeneity of dispersion of CB should be improved. In this study CB was coated with polyaniline prepared by in-situ polymerization of aniline. The result of PTC intensity and the reproducibility of resistivity-temperature curve in heating / cooling cycles of polyaniline coated CB was compared with those of CB filled polyurethane composite. In the measurement of PTC/NTC curve, a digital multimeter and programmable oven was used. The degree of aggregation of polyurethane / CB and polyurethane / CB-PANI composites was compared from SEM image. The effect of synthetic condition to the resistivity-temperature characteristics will be discussed. |
