With the rapid development of AI technology, AI servers have raised higher requirements for the dielectric properties of polyphenylene ether (PPO) materials. Conventional PPO has a high dielectric constant, making it difficult to meet the requirements of high-frequency signal transmission in AI servers for low dielectric constant, low dielectric loss, and excellent thermal stability. This paper reviewed the research progress of low-dielectric and low-dielectric loss PPO materials in recent years from both physical and chemical modification perspectives, summarized the application and development of modified PPO in core components of AI servers, and provided an outlook on its future development prospects.
