4D Printing of Seed Capsule‐Inspired Hygro‐Responsive Structures via Liquid Crystal Templating‐Assisted Vat Photopolymerization (Adv. Funct. Mater. 5/2023)

摘要

Hygroscopic Anisotropic Porous Structure In article number 2211602, Xiangjia Li, Kailong Jin, and co-workers present a versatile 4D printing technology, namely liquid crystal templating-assisted vat photopolymerization, which can fabricate bioinspired porous structures with hygro-responsive capabilities, opening an intriguing perspective for fabricating next-generation self-responsive structures with spatially gradient distributed pores and further provides opportunities for novel applications, including biomimetic soft robots, smart anticounterfeiting devices, flexible sensors, and ultrafiltration membranes.
