A Novel Positive Temperature Coefficient Composite with Low Curie Temperatures for Thermal Management.

Positive temperature coefficient (PTC) materials exhibit significant potential in thermal management due to their adaptive temperature regulation. However, current PTC materials are often constrained in the thermal regulation within the low-temperature range due to the high Curie temperatures. Achieving low Curie temperatures often requires small-molecule polymer matrices, which can compromise mechanical properties and lead to phase change material leakage.
