Hybrid functional microfibers for textile electronics and biosensors

Fibers are low-cost substrates that are abundantly used in our daily lives. This review highlights recent advances in the fabrication and application of multifunctional fibers to achieve fibers with unique functions for specific applications ranging from textile electronics to biomedical applications. By incorporating various nanomaterials such as carbon nanomaterials, metallic nanomaterials, and hydrogel-based biomaterials, the functions of fibers can be precisely engineered. This review also highlights the performance of the functional fibers and electronic materials incorporated with textiles and demonstrates their practical application in pressure/tensile sensors,chemical/biosensors, and drug delivery. Textile technologies in which fibers containing biological factors and cells are formed and assembled into constructions with biomimetic properties have attracted substantial attention in the field of tissue engineering. We also discuss the current limitations of functional textile-based devices and their prospects for use in various future applications.

A Review on Electrospinning as Versatile Supports for Diverse Nanofibers and Their Applications in Environmental Sensing

Rapid industrialization is accompanied by the deterioration of the natural environment.The deepening crisis associated with the ecological environment has garnered widespread attention toward strengthening environmental monitoring and protection.Environmental sensors are one of the key technologies for environmental monitoring,ultimately enabling environmental protection.In recent decades,micro/nanomaterials have been widely studied and applied in environmental sensing owing to their unique dimensional properties.Electrospinning has been developed and adopted as a facile,quick,and effective technology to produce continuous micro-and nanofiber materials.The technology has advanced rapidly and become one of the hotspots in the field of nanomaterials research.Environmental sensors made from electrospun nanofibers possess many advantages,such as having a porous structure and high specific surface area,which effectively improve their performance in environmental sensing.Furthermore,by introducing functional nanomaterials(carbon nanotubes,metal oxides,conjugated polymers,etc.)into electrospun fibers,synergistic effects between different materials can be utilized to improve the catalytic activity and sensitivity of the sensors.In this review,we aimed to outline the progress of research over the past decade on electrospinning nanofibers with different morphologies and functional characteristics in environmental sensors.

Improved anticorrosion performance of mixed valence Mnmodified ZnO dilute magnetic solid solution with multilevel selfassembled network structure

The design and performance prediction of efficient anticorrosion materials is a work full of value,novelty,and challenges.In this work,from the perspective of nanostructure and composition,ZnO-based dilute magnetic solid solution(DMSs)with hydrophobic micronano network structure was synthesized through the self-induced effect of raw materials,the impact-resistant network structure,complex micro-channels,and densely nested layers resisted electrolyte intrusion.Further,the doping of mixed valence Mn element endowed the solid solution with dilute magnetic properties,so the Lorentz force from micromagnetic field changed the movement path of electrons produced by the anode reaction to improve the corrosion inhibition ability of the protective layer.Under the synergy of morphology and magnetism,the corrosion resistance of the DMSs materials was 555.4%and 173.8%higher than that of epoxy resin and ZnO shielding layer,respectively.Besides,a valuable phenomenon was found that the photocatalytic property of DMSs materials was positively correlated with their corrosive defense.In conclusion,this research provided a novel design idea for new high-efficiency anticorrosion materials.
