摘要
Melamine-formaldehyde(MF) aerogels modified by phloroglucinol were prepared using melamine, phloroglucinol and formaldehyde by means of sol-gel and CO2 supercritical drying process. The lowest density of the modified MF aerogels is about 44 mg/cm3. The aerogel samples are transparent and unbroken. It is proved that shortening gelation time is caused by phloroglucinol through the Materials-Studio computer simulation. The samples were also characterized by SEM, FT-IR and TGA. These tests show that: the modified aerogels have the three dimensional space network structure, with uniform pore size distribution and thermostability.
