Abstract The growing field of 4D printing has spurred extensive exploration into applications stimulus-responsive materials, such as hydrogels for micro-actuators. However, the hydrogel-based micro-actuators fabricated by one-step, single-material are typically bilayer, and their actuation capabilities limited. This study proposes a novel gradient strategy via two-photon polymerization (2PP) based to enhance performance hydrogel feasibility this approach was demonstrated investigating shrinkage rates elastic moduli poly( N -isopropylacrylamide) (PNIPAm) micro-cuboids printed at different laser doses using confocal scanning microscope atomic force microscopy nano-indentation respectively. 2PP-based used fabricate bilayer trilayer PNIPAm micro-actuators, with dose programmed modulate crosslinking degree each layer. These were actuated near-infrared (NIR) light in gold nanorods (AuNRs) solutions. effects NIR powers, micro-actuator sizes, layer thicknesses on behaviors systematically investigated. Compared 12-µm-thickness micro-actuation, introduction transitional one significantly enhanced amplitude speed (the bending angle curvature increased about 150 70%, respectively, cycle time recovery shortened 35%). advancements have significant implications microscale materials enhancing applications.

Multiresponsive Bilayer Hydrogel Actuator with Switchable Shape Morphing Capability and Visible Color/Fluorescence Change

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(26), P. 34125 - 34134

Published: June 18, 2024

Bilayer hydrogels, endowed with multiresponsive and switchable color-changing properties, have garnered significant attention for bioinspired artificial intelligent materials. However, the design fabrication of such hydrogels that can fully mimic adaptation live organism, i.e., simultaneous changes in shape, fluorescent, and/or visible color, still remain challenges. Herein, a (e.g., temperature, salt, pH) multiadaptive (shape, fluorescent color changes) hydrogel was fabricated by employing monomers featuring pH-responsive fluorescence 4-(2-(4-(dimethylamino) phenyl)-1-isocyanovinyl) phenol (DP) 4-(2-sulfethyl) −1-(4-vinylbenzyl) pyridinium betaine (VPES). The bilayer comprises temperature- gel layer, poly(N-isopropylacrylamide-co-2-(dimethylamino) ethyl methacrylate), along pH-, temperature-, salt-responsive poly(acrylamide-co-2-(dimethylamino)ethyl methacrylate-co-VPES)@DP. Due to opposite swelling/shrinking behavior between two layers, prepared exhibits shape response thermal, pH stimuli, change originate from DP polyVPES, respectively. Apart behavior, this also shows an excellent antifatigue property high sensitivity, which makes it hold potential many applications. We anticipate strategy realize capability work inspire biomimetic smart
