Abstract
Shape memory polymers (SMPs) are a class of smart materials that can be programmed to recover from temporary shape to permanent shape by applying external stimuli (temperature magnetic field light electric field and moisture etc.). This unique property of SMPs makes them an appealing candidate in application for soft robotics such as smart actuators artificial muscles and biomedical devices. In this contribution we have developed multi-stimuli-responsive SMPs from bio-based benzoxazine resin and iron oxide nanoparticles (Fe3O4 NPs) that could be actuated by magnetic field and light. The nanocomposites were characterized by infrared spectroscopy in which molecular interaction between benzoxazine/epoxy copolymers and Fe3O4 NPs was observed. Effects of nanoparticle content (0�wt%) on magnetic mechanical thermal and thermo-mechanical properties of nanocomposites were investigated. Shape memory performance of nanocomposites was significantly improved with incorporation of Fe3O4 NPs. Shape fixity increased from 85% of neat copolymers to 93% of copolymers filled with 3 wt% Fe3O4 NPs while shape recovery increased from 94% to 98%. Moreover shape fixity could be done without external force contact by 808 nm-light actuation and magnetic attraction due to photothermal and magnetic properties of nanocomposites. Shape recovery was tested under actuation by magnetic field. The highest shape recovery ratio was 99% within 26 s for copolymers filled with 5 wt% Fe3O4 NPs. Lastly preliminary application of nanocomposites was demonstrated as they could push a 1 g-object within 10 s of actuation by magnetic field. In overall these nanocomposites with multi-stimuli-responsive shape memory property had a good potential to be applied for soft robotics. ? 2023 Kingfa Scientific and Technological Co. Ltd.
