“…The shape memory mechanism of unidirectional SMPs is the foundation for understanding all SMP deformation processes . As shown in Figure A, taking thermally triggered dual-SMP as an example, under the appropriate stimulus, such as increasing the temperature, the dynamic interactions are disrupted, and the moving and deforming ability of polymers is enhanced.…”

In recent years, shape memory polymers (SMPs) and self-healing polymers (SHPs) have been research hotspots in the field of smart polymers owing to their unique stimulus response mechanisms. Previous research on SHPs has primarily focused on contact repair. However, in instances where substantial cracks occur during practical use, autonomous closure becomes challenging, impeding effective repair. By integration of the shape memory effect (SME) with SHPs, physical wound closure can be achieved via the SME, facilitating subsequent chemical/physical repair processes and enhancing self-healing effectiveness. This article reviews key findings from previous research on shape memory-assisted self-healing (SMASH) materials and addresses the challenges and opportunities for future investigation.

Smart soft materials are the focus of extensive research efforts due to their potential applications in various fields. Inspired by nature, embedding smart micro‐inclusions in a soft substrate provides a feasible strategy to integrate the smartness of individual microparticles for creating smart materials at the macroscale, broadening the capabilities and applications of smart soft materials. This strategy decouples the design of intelligence and substrate materials, leading to a broader design space for both the smartness and the mechanical properties of the composites. In this Perspective, recent advances in creating smart soft materials using smart microparticles are summarized. The methods developed to construct composites of microparticles in a soft matrix are first introduced, followed by detailed discussions on the material compositions, stimuli and responsiveness, and properties of individual microparticles and the composite systems. Various applications based on advanced functionalities and capabilities that are enabled by those smart soft materials are highlighted. This study also points out research directions to further advance unconventional smart soft materials following this bioinspired approach.

Natural mollusks perform complex mechanical actions through reversible large‐strain deformation and stiffness switching, which are challenging to achieve simultaneously in synthetic materials. Herein, it is shown that a set of polyacrylates designed according to a chain friction and lubrication balanced strategy shows ultra‐stretchability (λ up to 324), high resilience (near 100% recovery at strain ≥ 100), and wide‐span stiffness switching (up to 2073 times). The typical emulsion polymerization method and casting technique are adopted to fabricate the polyacrylate films. Quaternary ammonium surfactants are used as the emulsifier and reserved in the polymer matrix to enhance the chain segment lubrication with their long alkyl group but improve the whole chain friction through the formation of nano‐eutectics. These polyacrylates undergo multimodal mechanical responses, including temperature‐ or time‐programmed deformation and load‐bearing like artificial muscles. This molecular design principle and synthetic method provide a robust platform for the fabrication of ultra‐tough polymers for soft robots with multiple customized functions.
