Porous carbon microspheres (PCMSs) have been prepared by hydrothermal method at low temperatures after the annealing with glucose crystal as raw materials in the reaction vessel. The samples were characterized by electron microscopy, infrared spectroscopy, X-ray diffraction, thermogravimetry and pore size analysis. The results showed that PCMSs, with uniform size, smooth surface, regular morphology and solvent dispersion, were prepared at optimum conditions of 0.3 mol/L glucose, 14 h and 180℃. The annealed PCMSs with a specific surface area of 502.6 m2/g and sizes ranging from 100–700 nm, had pore sizes concentrated at 1.2–1.8 nm and several oxygen-containing functional groups including hydroxyl, carbonyl and carboxyl groups on their surfaces. As-obtained PCMSs will eliminate the surface activation and improve the grafting reactivity in order to solve the complexity of modification in the process of preparingmolecularlyimprintedsurfacematerials.% 以葡萄糖晶体为原料,采用低温水热法和退火处理制得多孔碳微球.利用扫描电子显微镜、红外光谱仪、X-射线衍射仪、热重分析仪和孔径分析仪对所制备的碳微球进行表征.结果表明:通过调节低温水热反应中反应物浓度、反应时间、反应温度等参数,在葡萄糖溶液浓度0.3 mol/L、温度180℃、时间14 h时,得到粒径尺寸均一、表面光滑、形貌规整并且具有一定溶剂分散性的碳微球;退火后碳微球的尺寸均匀介于100~700nm之间,孔径集中分布在1.2~1.8nm之间,比表面积为502.6m2/g,表面具有羟基、羰基、羧基等含氧官能团.此多孔碳微球有望在表面分子印迹聚合物的制备过程中省去表面氧化的步骤,提高进一步接枝的反应活性,解决在表面分子印迹过程中修饰过程复杂的问题.
