Due to their profusion, high durability, and rigidity, lesser weight and biodegradable nature nanocellulose (NC) is observed as the challenging tasks for the aspirants in making of the green composites. The continuous network of the cellulose nanoparticle connected through hydrogen bonding is happened mainly due to the reinforcing effect allocated to the mechanical reoccurrence phenomenon of the NC. When comparing with the nanocrystalline cellulose, the NC has significant convincing progress in the durability and rigidity, and the aspect ratio of the NC is higher than that of the NC crystal. The reinforcement effect of NC is the characteristic of the NC polymer interaction as well as the reinforcement effect eventualizing through stress transfer at the NC–polymer interface. Thus, the concentration of the reinforcement particle rises to the saturation level due to the frailty of the NC reinforcement constituent and due to surface compliance between the matrix and the filler. Due to its structural firmness and mechanical behaviors, the NC compounds are used in many industrial applications like tissue engineering, food packaging, and electronic applications. The stretchable electronic systems and instruments are awaiting the maximal attention due to its essential applications in certain domains, such as robotics artificial intelligence, brain control and machine interface, clinical devices, and health care electronic monitoring devices. In addition to that, when realizing the operational performance of electronic devices, the electronic instruments and systems must be physically expandable and flexible. The proposed study deems the technique of reinforcing the NC compounds as green agent in electronic applications, which has been associated with the composites of polymer matrix. The elongation could be achieved through the formulation of composition via elastomers. In addition, it is being focused on the illustration of functional soft development of materials that is inclusive of the conductive intrinsic polymers for the elongated electrodes and electrothermal conversion and vice versa, occupying the maximal area along with tactile sensing elements.

In this work, we produced cross-linked electrospun hybrid scaffolds composed of gelatin/poly-d,l-lactide (PDLLA), gelatin/PDLLA/nanocellulose, and gelatin/PDLLA/cellulose nanocrystals/elastin. Fourier-transform infrared spectroscopy, X-ray diffraction, and high-performance liquid chromatography demonstrated the complete embedding of each component in the hybrid scaffolds. The degree of cross-linking was quantified by the 2,4,6-trinitrobenzenesulfonic acid assay, and attenuated total reflectance spectroscopy revealed the effectiveness of the cross-linking reaction. Notably, the interconnected porous structure revealed in uncross-linked scaffolds persisted even after cross-linking. Scaffolds were characterized in water through their contact angle showing total wettability. We investigated their mechanical properties by uniaxial tensile testing, which showed that even in the dry state, nanocellulose- and elastin-containing scaffolds exhibit higher elongation at rupture compared to those with pure gelatin/PDLLA. Therefore, we succeeded in tuning the toughness of the scaffolds by modulating the composition. In order to use scaffolds as medical devices, we assayed fibroblasts on scaffold extraction media, indicating that they were noncytotoxic. Finally, the attachment and proliferation of fibroblasts on the surface of different scaffolds were evaluated.

Owing to their abundance, high strength and stiffness, and low weight and biodegradability, nanocellulose (NC) is regarded as a promising candidate for the preparation of green composites. The high reinforcing effect assigned to the mechanical percolation phenomenon of NC is due to the stiff continuous networks of cellulosic nanoparticles linked via hydrogen bonding. Compared to nanocrystalline cellulose, NC fibers result in more significant improvement to the modulus, stiffness, and strength as aspect ratio NC fiber is higher compared to NC crystal. Indeed, in the case of biopolymer composites, the reinforcement effect of NC is attributed to the NC‐polymer interactions and the reinforcing effect occurring through effective stress transfer at the NC‐polymer interface. The NC‐reinforced composites tend to become more brittle as the concentration of the reinforcing particles increase up to the saturated level, due to the reduction in surface adhesion between filler and matrix. Due to its promising mechanical and structural stability, NC composites have been used widely in many industrial applications such as food packaging, electronic applications, and tissue engineering.
