Laser Fusion Research Center, CAEP, Mianyang 621900, China

摘要

摘要: 在惯性约束聚变（ICF）实验中，可通过在低密度聚合物泡沫中引入氯、氩、锗、铜等元素来调控辐射不透明度、改善流体力学稳定性及实现温度、密度示踪诊断。本文综述了掺杂聚合物泡沫的制备研究现状，分析了当前掺杂过程中存在的问题，并展望了未来面向高重复频率、高掺杂精度需求的技术发展趋势。该综述可为ICF实验靶材料的设计与制备提供参考。

Abstract: This paper focuses on the element doping technology of low-density polymer foams for inertial confinement fusion (ICF) experiments and summarizes their research status and development trends. As key target materials for ICF, low-density polymer foams can optimize radiation transport, suppress hydrodynamic instability, and achieve diagnostic functions by introducing doping elements such as chlorine, argon, and germanium. The paper systematically analyzes the principles, advantages, disadvantages, and application bottlenecks of two major types of technologies: physical doping (particle dispersion, physical vapor deposition) and chemical doping (copolymerization, monomer functionalization, polymer substitution), with an emphasis on core issues such as uniformity control and doping precision. Finally, it looks forward to cutting-edge directions including composite doping, two-photon polymerization, and ion implantation, providing technical references for the high-performance and precise preparation of ICF target materials and facilitating the development of high-repetition-rate ICF experiments.
