Paper Title:
Preparation, Characterization and Infrared Emissivity Properties of Cu / Polyurethane Composite
  Abstract

By the addition of flake Cu particles to polyurethane the infrared emissivity of polymers can be decreased significantly. In this work, the flake copper particles were prepared by solution phase reduction method. The PU pre-polymer was prepared by a typical method which using polyether polyol N220 and tolylene diisocyanate (TDI). Cu/Polyurethane composite was prepared by using incorporation method. The structure and morphology of Cu particles and Cu/Polyurethane composite were characterized by Fourier transform infrared spectrum spectroscopy (FTIR), scanning electron microscope (SEM), X-ray diffraction (XRD) and Energy Dispersive X-ray Detector (EDS). Moreover, the effects of copper particles content on infrared emissivity properties of composite were studied too. The results show that the flake Cu particles were prepared and dispersed well in polyurethane matrix. The infrared emissivity of composite was decreased with increasing particles loading. The composites get lowest infrared emissivity 0.546 when the loading of fillers increased to 20%.
