Figure 4. (A) Photographs and (B) SEM images of PGAA-PTA under different compressive strains; (C) Rf and Rr of PGAA-PTA; (D) Thermomechanical curves of PGAA-PTA-60% during the shape memory process; (E) Schematic illustration of the shape-memory mechanism of PGAA-PTA; (F) 3D RL curves under different compressive strains. SEM: Scanning electron microscopy; PGAA-PTA: polyimide/reduced graphene oxide/AgNW-poly(thioctic acid) aerogel; 3D: three-dimensional; RL: reflection loss; EAB: effective absorption bandwidth.
