摘　　要：以二乙烯基苯(DVB)为泡沫骨架材料,金纳米粒子为掺杂材料,邻苯二甲酸二丁酯为溶剂,聚(4-乙烯基苯酚)(PVP)为分散剂,5%(质量分数)聚乙二醇(PEG)为水相,通过悬浮聚合制备出纳米金掺杂DVB泡沫微球。分别采用扫描电镜、X射线能谱、傅里叶红外光谱、X射线衍射、热重分析和X射线断层扫描对掺杂DVB泡沫微球化学结构、金纳米粒子掺杂量以及分散性进行了表征。结果表明,分散剂含量为5 mg/mL时,金纳米粒子在泡沫中分布均匀,无明显沉降或团聚,金含量为5.2%,与理论值(5%)接近。该纳米金掺杂DVB泡沫微球在惯性约束核聚变(ICF)物理诊断实验中存在潜在应用。Gold nanoparticles doped DVB foam microspheres are prepared by suspension polymerization with divinyl benzene(DVB)as foam skeleton material,gold nanoparticles as doping material,dibutyl phthalate as solvent,poly(4-vinyl phenol)(PVP)as dispersing agent and 5wt%polyethylene glycol(PEG)as water phase.Scanning electron microscope,X-ray energy spectrum,Fourier-infrared spectroscopy,X-ray diffraction,thermogravimetric analysis and X-ray computed tomography are used to characterize the chemical structure of DVB foam microspheres,the doping amount and dispersion of gold nanoparticles in the DVB foam microspheres.The results show when the dispersant content is 5 mg/mL,the gold nanoparticles are uniformly distributed in the foam without obvious sedimentation or agglomeration.The gold content is 5.2%,which is close to the theoretical value(5%).The gold nanoparticles doped DVB foam microspheres have potential applications in inertial confinement fusion(ICF)physical experiments.
