摘要：
The polyamide (PA) aerogels with good-formability via a sol-gel technology were facilely fabricated by using melamine and aroyl chloride followed by CO2 supercritical drying. The synthesis procedure was straightforward and simple, relying on no nitrogen-based protective atmosphere. The influences of aroyl chloride monomer on the gelation time and aerogel structure were discussed. The structural properties of PA aerogels were characterized by the scanning electron microscopy (SEM) and Brunauer-Emmett-Teller methods (BET). The results indicated that the PA aerogels had a typical three-dimensional porous structure. The PA aerogels exhibited well multifunctional properties, such as flame resistance, thermal insulation, dielectric characteristics and mechanical properties. Due to well multifunctional properties, the PA aerogels had potential for the use in construction and building materials.
