Abstract
In this study the influence of modifying ZnO filler with surfacetreating agents on the thermal conductivity of the ethylenevinyl acetate copolymer EVA composites was reported Fourier transform infrared FTIR spectroscopy and scanning electron microscopy SEM were applied to analyze the surface modification of ZnO filler and the fractured surface morphology of the EVA–ZnO composites The test results indicated that surfacetreating ZnO filler with the valid modifying agents stearic acid OLAT16 KH560 or NDZ132 at right dosage and treating temperature the thermal conductivity of the EVA–ZnO composites can be enhanced effectively on account of reducing the interfacial phonon scattering while the dosage of modifying agents exceed a right amount the thermal conductivity of EVA–ZnO composites modified with the smallmolecule treating agents F1 nOctylic acid or stearic acid descend more evidently with the dosage increase
