1. Fabrication of bilayer actuator composed of a hygroscopically active layer with aligned nanofibers and an inactive layer.
Fabrication of bilayer actuator composed of a hygroscopically active layer with aligned nanofibers and an inactive layer. (A) Experimental apparatus to directionally electrospin nanofibers of polymer solution. (B) Formation of bilayer structure by detaching the active layer from the collector drum with the adhesive inactive layer. (C) Schematic of the bending deformation of the bilayer and SEM images. Left: Top view of the active layer. Right: Cross-section of the bilayer.
