NIR-Mediated Deformation from a CNT-Based Bilayer Hydrogel

Polymers, Journal Year: 2024, Volume and Issue: 16(8), P. 1152 - 1152

Published: April 19, 2024

Shape-shifting polymers are widely used in various fields such as intelligent switches, soft robots and sensors, which require both multiple stimulus-response functions qualified mechanical strength. In this study, a novel near-infrared-light (NIR)-responsible shape-shifting hydrogel system was designed fabricated through embedding vinylsilane-modified carbon nanotubes (CNTs) into particle double-network (P-DN) hydrogels by micellar copolymerisation. The dispersed brittle Poly(sodium 2-acrylamido-2-methylpropane-1-sulfonate) (PNaAMPS) network of the microgels can serve sacrificial bonds to toughen hydrogels, CNTs endow it with NIR photothermal conversion ability. results show that embedded P-DN present excellent strength, i.e., fracture strength 312 kPa strain 357%. Moreover, an asymmetric bilayer hydrogel, where active layer contains CNTs, achieve 0°–110° bending deformation within 10 min under irradiation realise complex movement. This study provides theoretical experimental basis for design manufacture photoresponsive actuators.

Deformation and Fracture Behaviors of Tough Plasticized Poly(vinyl butyral) across Broad Temperature and Strain Rate Ranges

Macromolecules, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 12, 2024

Understanding the deformation and fracture behaviors of amorphous polymers, particularly those toughened via dynamic bonds, is crucial for their practical applications further material design. In this study, plasticized poly(vinyl butyral) (p-PVB) chosen as a model system, characterized by heterogeneous distribution hydrogen strong dynamical asymmetry, exhibiting stretch-induced phase separation. Through measuring examining time–temperature superposition principle on viscoelastic modulus in mechanical analysis (DMA) tests, hysteresis energy loading–unloading rupture work uniaxial tensile toughness pure shear tests across broad strain rate temperature ranges, we have specifically elucidated critical roles bulk viscoelasticity separation dissipation during p-PVB. p-PVB, makes significant contribution to its dissipation, retards crack propagation, enlarges strain. The systematic investigations not only enable prediction pathway p-PVB products, such interlayer films used laminated glass, but also provide guidance designing polymers with similar structures great capability fracture.
