合成了聚苯二亚胺衍生物(PPBs)，并在流动的Ar气氛下从室温到900℃进行热解炭化，得到了高产率的多孔炭材料。用X射线衍射仪、拉曼光谱、电子显微镜和氮气吸附等方法研究了碳化材料的纳米结构和石墨化行为。碳化材料由平均尺寸为2~4 nm、层间距为0.4 nm的碳化层基本结构单元组成。纳米空间是通过组织基本结构单元而形成的，这导致了材料的微孔率。碳化材料在较高温度下很难石墨化。
Poly(phenylenebutadiynylene) derivatives (PPBs) were synthesized and carbonized by thermolysis from room temperature to 900°C under flowing argon, affording porous carbonaceous materials in high yields. The nanostructures and the graphitization behavior of the carbonized materials were investigated by XRD, Raman, electron microscopy, and N2adsorption methods. The carbonized material was made up with basic structural units of carbonaceous layers having an average dimension of 2–4nm and a wide interlayer distance of 0.4nm. The nano-space was created by organization of the basic structural units, which resulted in microporosity of the material. The carbonized materials were hard to graphitize by heat treatment of higher temperature.
