    摘要: The invention provides a carbon-based polymer PTC ink composition with enhanced heating uniformity to reduce the risk of hot spots across the PTC thick film fabricated from the PTC ink by addition of boron nitride. The added boron nitride is thermo-conductor and electric non-conductor. The presentation of boron nitride in carbon-based polymeric PTC film improves the temperature homogeneity across the film and maintains the desired PTC effect of the heating device. The content of boron nitride based on the total PTC composition in the invented PTC ink composition is 10-50 wt. %.
