What is Morphology Controlled Carbon Aerogel with Enhanced Thermal Insulation and Mechanical Properties: a Simple Route for the Regulated Synthesis about?

A simple route was proposed to prepare size-controlled carbon aerogel with superior thermal insulation and mechanical properties. Boron-modified phenolic resin (BPR) and hexamethylene-tetramine (HMTA) were crosslinked to build three-dimensional network structure initially followed by CO 2 supercritical drying and carbonization. In order to regulate the microstructure of BPR aerogels, the best proportion of HMTA to BPR was confirmed as H/P = 1/5 based on the micromorphology performance in SEM. The interaction between HMTA and BPR was also studied by FTIR spectra, and microstructure evolution of the target product-carbon aerogels were illustrated by SEM technique. SEM patterns indicated that the carbon aerogels maintain a stable porous structure at 1000 • C (carbonization temperature), and pore size distribution were between 321~612nm based on N 2 adsorption-desorption method. The synthesis method is convenient and flexible, permitting a tailor of porous structure, mechanical strength, density and thermal conductivity by adjusting carbonization temperature and time. Consequently, the obtained carbon aerogel with high compressive strength (1.0~2.3 MPa), low density (0.16~0.26 g‧cm -3
