This column mainly introduces the research progress of electrospun nanofibers, innovative products of nanofibers, high-level articles on nanofibers.
In this paper, the basic principles, control parameters, materials, and partial nanofiber structures of electrospinning are described. The electrospinning device, part of the collecting device and the nozzle module designed based on the theory are introduced. In addition, two nanofiber additive technologies, 3D printing and near-field electrowriting, are also introduced.
In the field of sensors, the stable and durable flexible stretchable conductor is still a great challenge that restricts its development. Electrospun nanofibers with high surface area to volume ratio can be used to develop sensors with higher load capacity, better sensitivity and faster response time. This paper has collected five articles about the latest progress of sensors from June to July for everyone to study.
As a new 3D printing technology, melt electrostatic direct writing (MEW) is more flexible. In the new study, a melt electrostatic direct-writing device constructs released mesh curled micropatterns that mimic the natural bone-ligament interface structure.
This paper sorts out five studies on electrospinning published in ACS Nano from April to June 2022, including applications in sensors, drug adsorption, agriculture, etc. these documents can be studied and exchanged for everyone, hoping to provide new ideas for scientific research.
The article "APL Bioengineering" reviews the development trend of wearable devices and shows that electrospinning is a key technology for the development of wearable devices.
Recently, a study was published in the journal "Science" to construct a heart helical structure using a focused jet spinning method, which was improved based on centrifugal spinning technology.
Recently, a research team in Turkey has made a unique functional nano fiber air filter (FNA) composed of polyvinyl alcohol, carbon nanoparticles and tea extract through electrostatic spinning process. This filter has a significant effect in removing PM particle pollutants in the air.
The development of wearable electronics is still restricted by the lack of a stable and durable flexible stretchable conductor. The team from the Ningbo Institute of materials science and engineering of the Chinese Academy of Sciences has developed a new flexible electrode with low resistance, high stability and stretchability. This electrode solves the problems of incompatibility between conductivity and tensile ratio of flexible electrodes, as well as unstable electrical performance under cyclic deformation.
At the Beijing Winter Olympics, a magical mask appeared on the podium. This mask contains a layer of nanofiber membrane. The nanofiber membrane prepared by the electrospinning process can filter bacteria, viruses, and various particles, and also has the functions of breathability and anti-fog. After self-designed electrospinning production equipment, through the improvement of electrospinning process parameters and the use of environmentally friendly solvents, stable and continuous production of nanofibers can be achieved.
Electrospinning nanofiber yarn systems can coat core yarns with nanofibers at an angle. Nanofiber yarns can be made into elastic human tissue, and the coating of cells is conducive to tissue healing.
The composite structure of nanofibers has different functions due to the different properties of the material. The core-shell structured nanofibers are prepared by coaxial electrospinning, which can be composited with catalysts, drug molecules or biological factors, etc.
