间苯二酚-甲醛有机气凝胶粉末经过高温碳化处理得到其碳气凝胶粉末。利用全自动吸附仪进行了液氮温度下有机气凝胶粉末和碳气凝胶粉末的N2吸附孔结构表征,主要研究了有机气凝胶碳化前后孔径分布的变化。并采用透射电镜(SEM)和X射线衍射(XRD)对粉末进行分析,结果表明,经碳化后其比表面积有较大的提高(>500m2/g),粉末粒径减小(<100nm)。 Resorcinol - formaldehyde organic airgel powder after high temperature carbonization to obtain its carbon airgel powder. N2 adsorption pore structure characterization of organic airgel powder and carbon airgel powder at liquid nitrogen temperature was carried out by using a fully automatic adsorber. The changes of pore size distribution before and after carbonization of organic airgel were mainly studied. The powders were analyzed by transmission electron microscopy (SEM) and X-ray diffraction (XRD). The results showed that the specific surface area of ​​the powders increased greatly (> 500m2 / g) and the particle size decreased (<100nm).
