采用悬浮缩聚法制得烯丙基COPNA-BMI树脂微球,然后经过炭化处理后得到新型炭微球.采用SEM观察这种树脂微球及炭微球的表面形貌;采用FT-IR分析该树脂微球炭化过程官能团的变化;采用元素分析仪对不同温度下该树脂微球C、H、O、N元素的含量进行测定;采用XRD对炭微球的微晶结构进行分析.研究表明,炭微球到具有很好的球形和表面光洁度,其结构为无定形炭;随着炭化温度的升高,炭微球的C含量逐渐增加,H、O含量明显降低.

The copolymer of allyl condensed polynuclear aromatic (COPNA) resin and bismaleimide (BMI) was used to prepare resin microspheres by suspension method, and then novel carbon spheres were prepared by di-rect pyrolysis of the resin microspheres. The morphologies of the resin microspheres and carbon spheres were investigated through SEM. The chemical structures of the resin microspheres at different temperatures were characterized by FT-IR. The C, H, N, O contents were determined using element analyze instrument, and the structure of the carbon spheres were characterized by XRD. Results show that the carbon spheres with amor-phous carbon structure have good sphericity and smoothness. Moreover, the C content of the carbon spheres in-creases with increasing carbonization temperature, while H and O contents markedly decrease.
