“…Also, the amide II band (1554 cm −1 ) of CNCs shifts to lower wavenumber of 1550 cm −1 in the composite. So, FTIR data confirm the interfacial interactions between CNCs and S-xSBR via hydrogen bonds [12]. The interfacial interactions are benefit for the improvement of the composite properties, which will be illustrated in following section.…”

“…Additionally, it also can be reinforced by different nanoparticles [21][22][23][24][25]. Our previous work focused on the influence of CNCs on the preparation and properties of xSBR films without addition of crosslinking agent [12]. The CNCs can significantly improve the mechanical properties of xSBR film without sacrifice of transparency.…”

“…CNCs can form filler network in polymer matrix via hydrogen-bonded interactions, even when the CNCs volume fraction was only a few percent [19]. The formation of the rigid network leads to a high reinforcing effect on the polymer composites and enhanced waterresponsive mechanical properties [12,20].…”

“…Among the used reinforcing materials, polysaccharide nanocrystals (nanowhisker), such as cellulose [1,2], starch [3][4][5], and chitin nanocrystals [6][7][8][9][10][11][12], show great potential to improve the polymer's mechanical properties, thermal stability, and solvent responsibility without significant affecting the transparency. Many studies have shown that incorporating a small amount (1-10 %) of these nanocrystals into polymers can induce vast improvement in properties [1,13].…”

This study aims to develop and characterize the nanocomposites using sulfur cross-linked carboxylated styrene-butadiene rubbers (S-xSBR) as the matrix and chitin nanocrystals (CNCs) as nanofillers. The composites' morphology and properties were examined by light transmittances, fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), X-ray diffraction (XRD), dynamic mechanical analysis (DMA), thermo gravimetric analyzer (TGA), and tensile properties determination. The addition of CNCs has slight effect on transparency of the composite films. FTIR data confirm the interfacial interactions between CNCs and S-xSBR via hydrogen bonds. CNCs are uniformly dispersed in the matrix from SEM result. The addition of CNCs can significantly improve the tensile strength and modulus both in static and dynamic states. The tensile modulus and tensile strength of S-xSBR/CNCs composites with the 4 wt.% CNCs is 62.5 % and 97.6 % higher than that of pure S-xSBR. The storage modulus, glass transition temperature, and the thermal stability of the composites are higher than those of the neat S-xSBR. The mechanical properties of the composite films are water-responsive, as the swollen samples exhibit obviously decreased strength and modulus. The greatest mechanical contrast is shown in the S-xSBR/CNCs composites with 2 wt.% CNCs loading whose tensile modulus decrease from 60.4 to 6.1 MPa after swelling equilibrium. The significant reinforcement effect of CNCs on S-xSBR is attributed to the unique structure of CNCs and the interfacial interactions in the composite.

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.
