利用自行合成的五种有机高分子树脂作为碳化预聚体,系统分析了碳化处理条件对制备的树脂碳粉末材料比表面积的影响,同时还分析讨论了树脂的空间结构和元素组成对树脂碳粉末材料比表面积的影响。实验结果表明,碳化处理温度和碳化处理气氛对制备的树脂碳粉末材料比表面积有重要的影响,后者的影响程度大于前者。同时还发现,具有一维线性结构的有机高分子树脂制备的树脂碳粉末材料比表面积都高于相同碳化处理条件下的三维立体结构的有机高分子树脂制备的树脂碳粉末材料。对比分析了树脂中氧、硫、氮等元素对树脂碳粉末材料比表面积的影响规律,其影响程度为S>O>N.综合来看,杂原子对树脂碳化产物比表面积的影响大于树脂空间结构效应的影响。
The effects of carbonization conditions on the specific surface area of the prepared resin carbon powder were systematically analyzed by using five kinds of organic polymer resins synthesized by themselves as the carbonized prepolymer. The effects of the spatial structure and elemental composition of the resin on the surface area of the resin carbon Effect of specific surface area of powder material. The experimental results show that the carbonization temperature and the carbonization atmosphere have an important influence on the specific surface area of the prepared resin carbon powder. The influence of the latter is greater than that of the former. At the same time, it is also found that the specific surface area of the resin carbon powders prepared from the organic polymer resins with one-dimensional linear structure is higher than that of the resin materials prepared from the organic polymer resins with the three-dimensional structure under the same carbonization conditions. The effects of oxygen, sulfur, nitrogen and other elements on the specific surface area of the resin carbon powder were compared and analyzed. The influence degree was S> O> N. Taken together, the effect of heteroatoms on the specific surface area of the resin carbonized product is greater than that of the resin’s spatial structure.
