Study on Temperature Sensibility of Nano-Copper/Paraffin Materials

Abstract

In this paper, nano-copper/paraffin thermosensitive composite materials were prepared by high-energy ball milling, and pressed into the glass cylindrical tube by hot press molding. The micro-morphology and particle shape and microstructure of composite particles were observed by SEM, FI-IR, etc, the temperature sensibility of thermosensitive composite materials were tested by self-manufactured thermosensitive testing device. It shows that the way by which high-energy ball milling are prepared, the composite particle coated with good results, dense arrangement of particles, copper particles on the paraffin structure does not produce damage. With copper mass ratio increasing, the thermal conductivity of temperature sensitive composite is improved.
