| Abstract:In this study， aerogels were prepared using TEMPO-oxidized nanocellulose (TCNF)， mechanically prepared microcellulose (MFC)， and polyvinyl alcohol (PVA) as raw materials. To further enhance mechanical performance， the aerogel fibers were modified with 3-glycidoxypropyltrimethoxysilane (GPTMS) and polyethyleneimine (PEI). The modified aerogels exhibited excellent elasticity， with plastic deformation remaining below 5% after 50 compression cycles at 50% strain. In addition， the air filtration material with double-layer structure had been successfully prepared. Compared with single-layer materials， the double-layer structured materials exhibited significantly superior filtration performance. The comprehensive performance indicators were as follows： the filtration efficiency reached 77.67%， the pressure drop was 122 Pa， and the quality factor was 0.013 Pa⁻¹. |
