Abstract
En 中文
• Chitosan forms an interfibrillar membranous network in hierarchically porous aerogels. • A triple defense system diverts PAN degradation from gas release to char formation. • Peak heat release rate and total heat release of aerogel reduces by 39.6% and 56.1%. • The aerogel achieves a sound absorption coefficient above 0.96 from 3000 to 6000 Hz. • The aerogel integrates thermal insulation and antibacterial activity.
