摘要：
Branched aramid nanofibers (ANFs) form hydrogel or aerogels with highly porous frameworks having mechanical properties exceeding those from non-branched nanomaterials with higher elastic crystalline moduli. ANF 3-D percolating networks (3DPNs) are made into different shapes by controlling the assembly conditions. In an embodiment, polymers such as epoxy are impregnated into the 3DPNs through a spin-coating assisted gelation layer-by-layer deposition (scg LBL) process. The nanocomposite fabrication process enables control of the film structure and thickness with nanometer resolution.
