【[Macromol. Rapid Commun]】A Novel Anisotropic Hydrogel with Integrated Self‐Deformation and Controllable Shape Memory Effect
Although shape memory polymers have been highlighted widely and developed rapidly, it is still a challenging task to realize complex temporary shapes automatically in practical applications. Herein, a novel shape memory hydrogel with the ability of self‐deformation is presented. Through constructing an anisotropic poly(acrylic acid)–polyacrylamide (PAAc–PAAm) structure, the obtained hydrogel ex...

【[Chem. Commun]】Actuating and memorizing bilayer hydrogels for a self-deformed shape memory function
A general strategy for fabricating a double layer self-deformed shape memory hydrogel which includes a thermo-responsive actuating layer and a pH-responsive memorizing layer is presented. Compared with traditional shape memory polymer systems, the temporary shape of the hydrogel could be generated by a thermo-responsive actuating layer upon the trigger of heat without the need for an external forc...

[Macromol. Rapid. Commun.] A novel anisotropic hydrogel with integrated self-deformation and controllable shape memory effect
With the development of
shape memory polymers, temporary shapes created by simple manual deformation
could not meet many practical applications. Here, a novel controllable
self-driven hydrogel with shape memory effect is presented. Through
constructing an anisotropic poly(acrylic acid)-polyacrylamide (PAAc-PAAm)
structure, the obtained hydrogel exhibits stable self-driven behavior in
response to e...

Comparison of hydrogenated bisphenol A and bisphenol A epoxies: curing behavior, thermal and mechanical properties, shape memory properties
Hydrogenated bisphenol A epoxy resin was cured using different kind of curing agents,
resulting in epoxy networks with better shape memory properties than bisphenol A epoxy networks. The non-isothermal curing kinetics investigated by differential scanning calorimetry (DSC) demonstrated that hydrogenated bisphenol A epoxy showed lower curing reactivity than bisphenol A epoxy, while it stil...

Multiple-Responsive Shape Memory Polyacrylonitrile/Graphene Nanocomposites with Rapid Self-Healing and Recycling Properties
It
still remains a great challenge to endow the polymer materials with multiple
superior material properties by precise molecular design. Herein, we reported a
Diels-Alder (DA) based crosslinked polyacrylonitrile/graphene nanocomposite
(PAN-DA/GR), which has the multiple-responsive properties
of shape memory, self-healing, and reprocessing in addition to the enhanced
mechanical property. The graph...

【[Chemical Society Reviews]】Supramolecular shape memory hydrogels: a new bridge between stimuli-responsive polymers and supramolecular chemistry
Supramolecular shape memory hydrogels (SSMHs) refer to shape memory polymers, in which temporary shapes are stabilized by reversible crosslinks such as supramolecular interactions and dynamic covalent bonds. Following a brief introduction of the conventional shape memory polymers (SMPs), this tutorial review is focused to summarize the recent advancement in various reversible crosslinks employed t...

【Macromolecules】Fabrication of Liquid Protrusions on Non-Cross-Linked Colloidal Particles for Shape-Controlled Patchy Microparticles
The use of single particles as building blocks for the design and construction of advanced materials is generally recognized as a promising approach. This paper reports a novel double-speed swelling (DSS) technique to fabricate solid–liquid asymmetric monomer-swollen particles (MSPs) with adjustable and removable liquid protrusions on the surface of non-cross-linked poly(glycidyl methacryla...

Construction of Small-Diameter Vascular Graft by Shape-Memory and Self-Rolling Bacterial Cellulose Membrane
Bacterial cellulose (BC) membranes with shape-memory properties allow the rapid preparation of artificial small-diameter blood vessels when combined with microfluidics-based patterning with multiple types of cells. Lyophilization of a wet multilayered rolled BC tube endows it with memory to recover its tubular shape after unrolling. The unrolling of the BC tube yields a flatm...

[ACS Appl. Mater. Interfaces] Fe3+-, pH-, thermo-responsive supramolecular hydrogel with multi-shape memory effect
Poor, non-tunable mechanical properties as well as finite shape memory performance pose a barrier to shape memory hydrogels to realize practical applications. Here, a new shape memory hydrogel with tunable mechanical properties and multi-shape memory effect was presented. Three programmable reversible systems including PBA-diol ester bonds, AAc-Fe3+ and coil-helix
transition of agar were applied t...
