Conductive, stretchable, environmentally‐friendly, and strain‐sensitive elastomers are attracting immense research interest because of their potential applications in various areas, such as human–machine interfaces, healthcare monitoring, and soft robots. Herein, a binary networked elastomer is reported based on a composite hydrogel of polyvinyl alcohol (PVA) and polyethyleneimine (PEI), which is demonstrated to be ultrastretchable, mechanically robust, biosafe, and antibacterial. The mechanical stretchability and toughness of the hydrogels are optimized by tuning the constituent ratio and water content. The optimal hydrogel (PVA2PEI1‐75) displays an impressive tensile strain as high as 500% with a corresponding tensile stress of 0.6 MPa. Furthermore, the hydrogel elastomer is utilized to fabricate piezoresistive sensors. The as‐made strain sensor displays seductive capability to monitor and distinguish multifarious human motions with high accuracy and sensitivity, like facial expressions and vocal signals. Therefore, the elastomer reported in this study holds great potential for sensing applications in the era of the Internet of Things (IoTs).

“…Electrospinning is a simple and straightforward process which can be used to create nanofibers from polymer solutions or melts. It has attracted much attention in the research literature because the resultant nanofibers have many advantageous properties, such as large surface areas, high porosity, and a continuous 3-D web structure (Jiang, Uch, Agarwal, & Greiner, 2017;You, et al, 2018;Wang, et al, 2017;Habiba, et al, 2018;Wali, et al, 2018). The process involves the ejection of a polymer solution through a needle, termed the spinneret, towards a collector plate.…”

In this study, novel core-shell nanostructures were fabricated through a modified triaxial electrospinning process. These comprised a drug-protein nanocomposite coated with a thin cellulose acetate (CA) shell. They were generated through the simultaneous treatment of an outer solvent, an unelectrospinnable middle fluid, and an electrospinnable core solution in triaxial electrospinning. SEM and TEM results revealed that the core-shell nanofibers had linear and cylindrical morphologies with a diameter from , and distinct core-shell structures with a shell thickness from 1.8 to 11.6 nm. The presence of a CA coating eliminated the initial burst release of ibuprofen seen from a monolithic drug-protein composite, and allowed us to precisely manipulate the drug release (for a 90% percentage) over a time period from 23.5 to 43.9 h in a tunable manner. Mathematical relationships between the processing conditions, the nanostructures produced, and their functional performance were elucidated.

“…The elasticity of fibers increased by more than 100% with the addition of zeolite to chitosan/PVA which increased the brittleness and UV–vis spectra of treated dye confirmed that methyl orange is present on the dye due to characteristic of benzene and azo linkage from methyl orange with a capacity of 153 mg g −1 . Another study on the inclusion of silica composite to PVA‐chitosan was reported by Mahmoodi which induced the property of gel and provided more sites for electrospinning with a recovery of 96% for Direct Red 80 . Loading ZnO nanoparticles on PVA composite nanofibers effectively decolorized dye methyl orange with a removal efficiency of more than 99.99%…”

Studies involving bio‐based nanofibers are well utilized in the field of energy, catalysis, electronics, and environmental science. In this review, the importance of utilizing bio‐based materials for the development and optimization of multiplexed nanofibers and the modifications adopted to overcome the drawbacks of conventional electro‐spinning to facilitate better production rates, enhanced adsorption, and its potential in removing heavy metal ions, dyes, and other contaminants polluting the environment are highlighted. This work provides the readers the ability to understand the complexity in fabrication of bio‐based nanofibers focusing primarily on chitosan, cellulose, and protein‐based nanofibers and their mechanism toward quenching/degradation of water contaminants. In addition, it also provides the advantages of using bio‐based materials over synthetic materials for the development of nanofibers.
