Preparation of Tourmaline and Carbon Nanotubes Based Composite Materials and Its Heat Emission Performance

摘要

The tourmaline-based composite materials as an effective thermal coating of heat exchanger unit were prepared from natural mineral tourmaline, transition metal oxides and carbon nanotubes. The far infrared emission properties and heat emission performance were studied. The results indicated that thermal performance of materials can be adjusted with the chemical composition of materials, and when the mass percentage of carbon nanotubes is 10%, the fractional of 26.77% of energy saving efficiency can be achieved.
