Preparation and characterization of phloroglucinol-formaldehyde aerogel
Phloroglucinol-formaldehyde(PF) aerogels and carbonized PF(CPF) aerogels were prepared from Phloroglucinol(P) and Formaldehyde(F) by sol-gel,solvent exchanging,supercritical drying and carbonization processes.The aerogel has a large specific surface area,continuous nano-network and porous structure.The density and mean porosity radius will enlarge after being carbonizied,while the specific surface area will be influenced little.The micro-structure and density of aerogel are controlled by concentration of total reactants and catalyzer,respectively.Aerogels with different micro-structure and different density fit for ICF targets can be prepared by optimizing synthesis conditions.
