超低密度碳气凝胶的制备与研究
Preparation and Study of Ultra-low Density Carbon Aerogel
摘要
Abstract
The ultra-low density resorcinol (R)-formaldehyde (F) aerogel and carbon aerogel were prepared via a sol-gel route, which density are 10 mg/cm3 and 20 mg/cm3, respectively. The microstructures and properties of the carbon areogel were investigated by using scanning electron microscope, transmission electron microscope, pore size distribution measurement, and so on. The ultra-low density products are some tortuous chains consisting of carbon nanospheres ranging from 10 to 15 nm. The carbon nano-sphere consists of nanoparticles whose sizes are about several nanometers. The surface area of the low-density carbon aerogel is 1 783.7 mVg. The hydrogen adsorption capacity of the ultra-low density carbon aerogel is 4.4% (mass fraction) at liquid nitrogen temperature under atmospheric pressure.关键词
