Stimuli‐responsive polymers (SRPs) are special types of soft materials, which have been extensively used for developing flexible actuators, soft robots, wearable devices, sensors, self‐expanding structures, and biomedical devices, thanks to their ability to change their shapes and functional properties in response to external stimuli including light, humidity, heat, pH, electric field, solvent, and magnetic field or combinations of two or more of these stimuli. In recent years, additive manufacturing (AM) aka three‐dimensional (3D) printing technology of these SRPs, also known as four‐dimensional (4D) printing, has gained phenomenal attention in different engineering fields, thanks to its unique ability to develop complex, personalized, and innovative structures, which undergo twisting, elongating, swelling, rolling, shrinking, bending, spiraling, and other complex morphological transformations. Herein, an effort has been made to provide insightful information about the AM techniques, type of SRPs, and their applications including, but not limited to tissue engineering, soft robots, bionics, actuators, sensors, construction, and smart textiles. This article also incorporates the current challenges and prospects, hoping to provide an insightful basis for the utilization of this technology in different engineering fields. It is expected that the amalgamation of 3D printing with SRPs would provide unparalleled advantages in different engineering arenas.This article is protected by copyright. All rights reserved.

“…3,[6][7][8][9][10][11] The superior intrinsic properties and nano-sized effects of nanoparticles have made them an attractive platform for the fabrication of block copolymers with a wide variety of applications. [12][13][14] Among them, carbonbased nanoparticles, such as multi-walled carbon nanotubes (MWCNTs) and graphene nanoplatelets (GNPs), have proved to be capable of improving various properties in SEBS block copolymers due to the formation of preferential л-л interactions between delocalized electrons in the phenyl group of PS blocks and electron-rich carbon nanoparticles. 3 Wang et al 15 studied the effect of PS block content on the mechanical performance of SEBS/GNPs nanocomposites, finding that as a result of the possibility of forming more interactions, the enhanced mechanical properties of samples with higher PS content were more significant.…”

Polystyrene‐poly (ethylene‐butylene)‐polystyrene (SEBS) nanocomposites have been regarded as promising thermoplastic elastomers for several industries owing to their distinct molecular platforms and properties. However, extending their applications requires a thorough understanding of the microstructural changes that nanoparticles induce in SEBS chains. In this work, we used two types of SEBS varying in polystyrene (PS) hard block contents to study the relationship between the structural changes and viscoelastic/mechanical properties of SEBS hybrid nanocomposites containing different multi‐walled carbon nanotubes: graphene nanoplatelets ratios. According to the results, the viscoelastic responses were strongly influenced by the PS block content and nanoparticles ratio, which had an appreciable contribution to the nanoparticles' dispersion state. This was explained in terms of intensified microphase separation induced by the favorable interactions between the carbon‐based nanoparticles and PS blocks. It was also found that the samples containing higher hard block content demonstrated more significant mechanical performance and toughness, which were enhanced by the addition of nanoparticles such that the highest ultimate strength of 24.58 MPa was obtained for the S30C0.5G0.5 sample. Furthermore, some mechanisms, including molecular disentanglements, dissociation of inter/intra‐molecular interactions, the orientation of the rubbery polyethylene butylene chains, and PS microdomain rearrangement, were supposed to interpret the energy dissipation capability of SEBS nanocomposites.

Direct-ink writing (DIW) printing technology represents a suitable and efficient additive manufacturing technique for producing intricate designs and structures directly on the application surface. This work has demonstrated the potential of combining DIW and screen printing to fabricate an all-printed 7 × 7 capacitive touch sensor based on high dielectric constant (high-k) poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene)�P(VDF-TrFE-CFE). The printed device allows a maximum detection signal-to-noise ratio (SNR) of 20 dB, a large touch sensitivity that demonstrates the touch sensor's ability to detect and respond precisely to user input. Furthermore, by demonstrating the processability of P(VDF-TrFE-CFE) with DIW printing, this research also opens the way for the low-cost fabrication and integration of sensing devices based on this high dielectric constant polymer.
