摘　　要：通过机械球磨将PTFE微粉与环氧树脂混合,经固化后制得不同PTFE添加量的环氧树脂/PTFE复合材料。结果表明:PTFE微粉的添加显著降低了环氧树脂复合材料的介电常数、介质损耗和吸水率,同时也提高了复合材料的热分解温度。An epoxy/PTFE composite with various PTFE content was prepared by mixing epoxy and PTFE powder through mechanical ball milling and curing. It is found that the addition of PTFE pow- der can obviously decrease the dielectric constant （Dk）, dielectric loss （Dr） and water absorption of the epoxy composite and meanwhile increase the decomposition temperature.
