Stimuli‐responsive mechano‐adaptive materials, capable of reversibly changing their mechanical properties when exposed to an external stimulus, are the next generation of smart materials with immense transformative potential for various technological applications. Although the concept of adaptive mechanical properties has been proven for some materials, it remains very challenging for soft elastomeric materials. The aim of this review is to provide new ideas and strategies for the development of mechano‐adaptive elastomeric composites using commercial rubber as the matrix polymer. The fundamental question addressed here is: How do the phase‐responsive functional fillers alter the mechanical properties? For a given physical network environment, what is the mechanism that gives rise to the stimuli‐responsive properties of the resulting composites?? This paper summarizes the preparation, structure and properties of recently developed mechano‐adaptive elastomeric materials. Furthermore, based on their structure‐property relationships, plausible applications of these smart materials in various technology‐specific applications such as soft robotics, actuators, sensors, smart tires, automotive design, aerospace etc. are demonstrated with representative examples. Finally, the paper critically discusses the existing challenges in the field of mechano‐adaptive elastomers in order to provide valuable insights in this area.This article is protected by copyright.

“…Mainly, GO can interact strongly with a variety of macromolecules as well as small molecules (such as drugs, proteins, metals, biomolecules, and cells) via π-π stacking, covalent bonds, hydrophobic interactions, electrostatic forces, and hydrogen bonds. 11,12 Reductive exfoliation can convert GO into reduced graphene oxide (rGO). rGO is most commonly prepared by the chemical reduction of GO.…”

The article discusses the synthesis of a novel biodegradable poly(ester-imide) (PEI) based on L-alanine, utilizing N-trimellitylimido-L-alanine diacid and curcumin. The degradation tests of polymer in Tris-Hcl buffer at 37.5 C after 2 weeks showed a decrease in average molecular weight from 2.38 Â 10 4 to 1.85 Â 10 4 , which confirms the biodegradability of PEI. The PEI was further enhanced through in situ polymerization with reinforcing nanoparticles, rGO, and rGO-EDA. Various characterization techniques were employed to evaluate the synthesized polymer and composites, including NMR, elemental analysis, FT-IR, thermogravimetric analysis (TGA), and X-ray diffraction (XRD). PEI composites exhibited higher thermal stability than pure PEI. Tensile strength also improved significantly, with increases of 29.55% and 87.42% for rGO and rGO-EDA compared to pure PEI. We suggest that these polymers have tunable properties, which may potentially be considered for biodegradable polymer scaffolds.
