块状低密度C/SiO2复合气凝胶的制备
Preparation of monolithic C/SiO2 composite aerogels with low density
摘要
Abstract
Resorcin-formaldehyde/Si02 composite ( RF/SiO2) aerogels were synthesized by the sol-gel method and CO2 supercritical fluid drying. C/SiO2 composite aerogels were formed from the RF/SiO2 aerogels after carbonization. The influence of reactant concentration on sol-gel and thermal treatment processes was investigated. The effect of heat treatment temperature on pore structure of C/SiO2 aerogels was discussed. Results showed that the heat treatment had the least impact on RF/SiO2 aerogels with the reactant concentration of 13% , and increasing the carbonization temperature to 1 200 t had an obvious improvement to the network structure of C/SiO2 aerogels.关键词
