Shape memory is the capability of a material to be deformed and fixed into a temporary
shape. Recovery of the original shape can then be triggered only by an external stimulus …

Shape memory polymers (SMPs), as a class of programmable stimuli-responsive shape
changing polymers, are attracting increasing attention from the standpoint of both …

Shape memory polymers (SMPs) represent a highly interesting class of materials. As one
representative of the intelligent polymeric systems, these materials gained significant …

Abstract Four-dimensional (4D) printing of shape memory polymer (SMP) imparts time
responsive properties to 3D structures. Here, we explore 4D printing of a SMP in the …

Growing demand in portable electronics raises a requirement to electronic devices being
stretchable, deformable, and durable, for which functional polymers are ideal choices of …

Stimuli-responsive materials with sophisticated yet controllable shape-changing behaviors
are highly desirable for real-world device applications. Among various shape-changing …

They alternate their body color by stretching the skin to enlarge the embedded
chromophores.[23] Mechanical modulation is a common practice to control light …

This review summarizes progress toward programming two-dimensional (2D) polymer
sheets which respond to a variety of external stimuli to form three-dimensional (3D) shapes …

Supramolecular shape memory hydrogels (SSMHs) refer to shape memory polymers, in
which temporary shapes are stabilized by reversible crosslinks such as supramolecular …

Shape memory polymers (SMPs) are capable of changing their shapes in a pre-defined
manner under a stimulus, and have gained considerable interest in the past decades …
