| 摘 要： | 以聚-4-甲基-1-戊烯（PMP）为泡沫骨架，m量级钨为掺杂材料，超高分子量聚乙烯（UHWPE）为溶液粘度控制剂，通过热诱导倒相技术实现了低密度钨掺杂聚合物泡沫的制备。实验结果表明：当UHWPE质量分数为25%时，能够实现粒径10 m的钨在泡沫体内的均匀掺杂；泡沫密度为20 mg/cm3时，钨掺杂质量分数最高可达60%。

| Abstract: | Low-density tungsten-doped poly(4-methyl-1-petene) (PMP) polymer foams were prepared with thermal induced phase inversion method using PMP as the foam skeleton material, tungsten in micron dimension as doping materials, and upper ultra-high molecular weight polyethylene(UHWPE) as solution viscosity control agent. The results indicated that 10-m tungsten particle doped foams were synthesized uniformly when the mass content of UHWPE was 25%. The density of foam was 20 mg/cm3, while the mass content of doped tungsten reached up to 60%. |
