Low dielectric insulating materials with good adhesive properties and flame retardance are becoming increasingly important for achieving high-speed and low-loss communications in electronic devices. In this study, phosphine sulfide (P=S) group-containing aromatic poly(ether)s with low dielectric, good adhesive, and flame-retardant properties were developed. The poly(ether)s exhibited low dielectric constants (ε = 2.55–2.72) and low dielectric dissipation factors (tanδ = 0.0026–0.0045) at 10 GHz. From the discussion based on the DFT calculations, these low dielectric properties are probably due to the low polar nature of the P=S groups, resulting in low atomic and orientational polarization components. In addition, these polymers exhibited self-extinguishing behavior in the flame-retardant evaluation due to the presence of phosphorus atoms and good adhesion to a Cu substrate, which may be due to the coordination ability of the P=S groups. Such polymers are promising candidates for new insulating materials used in high-frequency electronic devices.

具有硫化膦基团的低介电、良好粘合性和阻燃芳香族聚醚

具有良好粘合性能和阻燃性的低介电绝缘材料对于实现电子设备中的高速和低损耗通信变得越来越重要。本研究开发了具有低介电常数、良好粘合性和阻燃性能的含硫化膦（P=S）基团的芳香族聚醚。聚醚在 10 GHz 下表现出低介电常数 ( ε = 2.55–2.72) 和低介电损耗因数 (tan δ = 0.0026–0.0045)。根据基于 DFT 计算的讨论，这些低介电性能可能是由于 P=S 基团的低极性性质，导致原子和取向偏振分量低。此外，由于磷原子的存在和对铜基材的良好附着力，这些聚合物在阻燃评价中表现出自熄行为，这可能是由于P=S基团的配位能力。此类聚合物是高频电子设备中使用的新型绝缘材料的有希望的候选者。
