Abstract Nano-copper/paraffin/expanded graphite thermo-sensitive composites were prepared by high energy ball milling. The samples were characterized by scanning electron microscope(SEM) and transmission electron microscopy(TEM). The thermal expansion, thermal sensitivity and thermal stability were investigated. The results reveal that copper particles are well coated by paraffin. The particles milled for 98 h are near-spherical in shape and the size of particles is about 100 nm. Nano-copper/paraffin composite particles are embedded in the pores of expanded graphite. Moreover, the expansion decreases with increasing the expanded graphite content, and the thermosensitivity can be improved effectively. Nano-copper/paraffin composites are stable above the phase transition temperature.
