摘要：Aluminum nitride/polyphenylene sulfide (AlN/PPS) composites were prepared using a melt-blended method, and the thermal, mechanical, morphology, and dielectric properties of the composites were systematically investigated. The results showed that the thermal conductivity of AlN/PPS composites increased with the addition of AlN, in various amounts, by forming a conductive network in the composites due to the filler. Wide-angle X-ray diffraction and scanning electron micrograph/energy dispersive spectrometry were employed to investigate the effects of AlN addition on the crystal property of the matrix. The test results showed that the crystallinity of the PPS increased with higher AlN content at first, and dropped when the volume content of AlN was over 15 vol%, that is because the AlN filler provided a heterogeneous nucleation effect on the PPS. Several thermal conductivity models were applied to predicate the thermal conductivity of AlN/PPS composites. The mechanical tests showed that the impact and flexural strength of the composites initially increased and decreased as the AlN contents increased. Thermogravimetric analyses showed that the thermal stability of PPS increased with the addition of AlN. The thermal conductivity of AlN/PPS composites was tested at different temperatures and it was found that by increases in temperature the thermal conductivity of the composites decreased. The electrical properties of the composites were also investigated.
