PTC Thermistors with Low Resistivity at Room Temperature
Wu Boyuan; Zou Xiang; Jiang Meiyu
V2O3 filler is added to polymer matrix to produce composite having low resistivity to 0.4 ohm. cm at room temperature and large PTC to the extent of 10 orders of magnitude. Dependence of V2O3 content,polymer kinds and content on thermistor resistivity at room temperature and PTC is discussed. Microstructure of the composite is analysised and PTC effect is explained in term of tunneling.
