“…170 Recently, the rise of soft robotics has led to the design of biomimetic actuators and artificial muscles. 19,125,163 In general, actuators are devices that can convert an external stimulus to mechanical motion. Taking advantage of the multiple shape-memory behaviors of ionomers, many actuators were designed using ionic polymeric materials.…”

“…Therefore, multidisciplinary research efforts have been directed toward developing tissue‐engineered constructs that could display sufficient mechanical properties, bioactivity, and resorbability. [ 6,91–104 ] Amongst the different materials explored in this direction, nanoclay reinforced materials have recently opened new perspectives for T/L and cartilage repair [ 24,32,87,92,97,104–113 ] mainly due to their improved mechanical performance and capacity to stimulate new tissue formation. For example, in vivo studies using a rat‐based artificial cartilage‐ligament reconstruction model observed that unidirectional‐braided silk‐based hybrid fibers with bioactive nanoclay Laponite RD displayed better cartilage remodeling compared with pristine counterparts ( Figure ).…”

Nanoclay‐reinforced biomaterials have sparked a new avenue in advanced healthcare materials that can potentially revolutionize treatment of musculoskeletal defects. Native tissues display many important chemical, mechanical, biological, and physical properties that engineered biomaterials need to mimic for optimal tissue integration and regeneration. However, it is time‐consuming and difficult to endow such combinatorial properties on materials via feasible and nontoxic procedures. Fortunately, a number of nanomaterials such as graphene, carbon nanotubes, MXenes, and nanoclays already display a plethora of material properties that can be transferred to biomaterials through a simple incorporation procedure. In this direction, the members of the nanoclay family are easy to functionalize chemically, they can significantly reinforce the mechanical performance of biomaterials, and can provide bioactive properties by ionic dissolution products to upregulate cartilage and bone tissue formation. For this reason, nanoclays can become a key component for future orthopedic biomaterials. In this review, we specifically focus on the rapidly decreasing gap between clinic and laboratory by highlighting their application in a number of promising in vivo studies.

“…After 48 h, the swollen sample was taken out from the solvent and gently pressed with tissue paper to remove the solvent from the surface before being weighed ( W ). After that, the percentage of swelling [ 42 ] of the sample was calculated as per Equation ()

Swelling (%) = \frac{(W - H)}{H} \times 100

Introduction of the self‐healing property in the commercially available elastomers promotes the development of high‐end elastomeric products with an extended lifespan. Herein, a smart functionalized carboxylated nitrile rubber (XNBR) is prepared based on dynamic phototriggered disulfide metathesis and thermoreversible Diels–Alder (DA) “click chemistry.” In this case, the XNBR is functionalized with furfuryl amine (FA) followed by crosslinking with a dual functional crosslinker having a maleimide as well as a disulfide functionality for participating in the DA reaction and to induce the UV‐triggered disulfide metathesis reaction, respectively. The self‐healing properties are studied by thermal, mechanical, and microscopy analyses. The crosslinked materials present an impressive self‐healing efficiency of ≈88% and a tensile strength of ≈10 MPa without affecting its oil‐resistance property whereas pristine XNBR and furfuryl‐functionalized XNBR (FXNBR) show tensile strengths only 0.4 and 0.6 MPa, respectively. Furthermore, the crosslinked rubber is demonstrated to be recyclable, without much loss of its mechanical properties. In a nutshell, the use of this smart dual pathway of self‐healing can pave a new direction in sustainable development in NBR elastomers.
