Infrared emissivity study of polypropylene/silver nanocomposites

摘要：

Polypropylene(PP)/Silver nanocomposites were prepared by melt blending by twin-screw extruder. The morphology and distribution of silver nanoparticles in PP matrix were investigated by transmission electron microscopy (TEM). Differential scanning calorimetry (DSC) results indicated that the silver nanoparticles is an effective nucleating agent for PP. The infrared emissivity study showed that the infrared (wave length 3-5μm,8-14μm,1-22μm) emissivities decrease significantly with the increase of the fraction of silver. The dielectric and electrical conductive properties of the composites were studied subsequently. The relationship between the electrical properties and infrared emissivity was discussed, and the mechanism were illustrated by optical theories related to infrared emissivity.
