Seed capsule-inspired hygro-responsive structures via liquid crystal templating assisted VPP

Inspired by the seeds release strategy by hygroscopic deformation, a 4D printing method utilizing photopolymerization induced phase separation and electro-alignment is established to fabricate liquid crystal (LC) based composites with anisotropic porous structures that can undergo fast and programable hygro-responsive deformation. This versatile LC template-driven nanofiller arrangement approach can lead to novel actuating and sensing nanocomposites fabrication.
