摘要
为保证医疗器械工作电极材料制备水平,提高医疗器械运行性能,本文制备生物质改性酚醛树脂基碳材料微球,以提高新型树脂材料的应用优势和应用价值。首先,分析LPR微球表征,发现木质素与酚醛树脂缩合反应,促使LPR表现出良好的热稳定性。通过制备生物质改性酚醛树脂基碳材料微球,并探讨该LPR微球在不同活化温度下所呈现的比表面积、孔体积变化。结果发现:在900℃活化温度、炭化温度下,通过制备LPR微球,可以最大限度地提高该LPR微球的比表面积和孔面积,其比表面积和孔面积最大值分别为1843.82 m^(2)/g、0.86 cm^(2)/g。
In order to ensure the preparation level of working electrode materials for medical devices and improve the operational performance of medical devices,biomass-modified phenolic resin-based carbon material microspheres were prepared in this paper to improve the application advantages and application value of new resin materials.First,the characterization of LPR microspheres was analyzed it was found that the condensation reaction of lignin and phe⁃nolic resin promoted the good thermal stability of LPR.By preparing biomass-modified phenolic resin-based carbon microspheres,and exploring the changes of specific surface area and pore volume of the LPR microspheres at differ⁃ent activation temperatures,it was found that the specific surface area and pore volume of the LPR microspheres could be maximized by preparing LPR microspheres at 900℃activation temperature and carbonization temperature,and the maximum specific surface area and pore volume were 1843.82 m^(2)/g and 0.86 cm^(3)/g,respectively.
