三嵌段共聚物F127为模板剂,线性酚醛树脂为碳前驱体,采用溶剂挥发诱导有机-有机自组装法(EI-SA)制备了具有二维六方结构的有序介孔碳.利用FT-IR、XRD、TEM、N2吸附/脱附等方法对有序介孔碳的结构进行了表征,研究了不同焙烧温度和模板剂用量对有序介孔碳结构的影响.结果表明,当模板剂的用量一定时,有序介孔碳的孔径、孔容和孔壁厚度都随着焙烧温度的升高而降低,但比表面积却随着微孔含量的增加而增大.随着模板剂用量的增加,介孔碳的有序性降低.有序介孔碳PF-2-500的比表面积、孔径、孔容、孔壁厚度和微孔比表面积比分别为583.82m2/g、3.05nm、0.31cm3/g、3.40nm和361.18m2/g,而有序介孔碳PF-1-500的比表面积、孔径和孔容相对于PF-2-500有所提高,分别为647.79m2/g、3.44nm和0.41cm3/g,但微孔比表面积和孔壁厚度分别降低为309.46m2/g和3.35nm.
