Electrospining Machine:IF as high as 39.5! Seeram Ramakrishna Fellows Nature Subjournal Review: Electrostatic Spinning Nanofibers

Background

Electrospinning is a technique for preparing Electrospun Nanofbers by stretching polymer solutions or molten polymers into fibers under the action of an electric field. The electrospinning technology has promising applications in nanomaterial preparation and functional material design.

Recently, academician Seeram Ramakrishna of National University of Singapore published a review titled “Electrospinning of nanofibres” in the journal Nature Reviews Methods Primers ( IF 39.5 ). The review summarizes the electrostatic spinning technology, material preparation, limitations of the electrostatic spinning technology, and its future directions.

The main points of this paper

1.This paper summarizes the principles, material selection, process parameters, equipment and application areas of electrospinning technology.

2.Introduction of electrospinning technology for the preparation of Nanofiber Membrane, stents, biomedical materials, energy memory devices and so on.

3.It also discusses the scalability of electrospinning machine, optimization strategy and future development direction.

How can electrospun materials be adapted to different applications in the environmental, energy, medical, textile and agricultural fields?

Environmental applications:

Electrospun Nanofbers can be used for environmental remediation by effectively removing harmful ions, particles and pollutants from polluted water and air due to their electrostatic force and high specific surface area.

energy applications: 

In the energy sector, by optimizing conductivity, energy density and stability, electrospun materials can be used in batteries, fuel cells and solar cells. Optimization of nanostructures or hybridized components of the new electrospun materials can improve energy storage and conversion performance.

Medical applications: 

Controlled release of drugs can be achieved by adjusting the properties of electrospun materials to suit the biological environment and ensuring biocompatibility.

Textile applications: 

Electrospun Nanofilaments can be used in functional textiles for a variety of purposes, such as smart sensors, actuators, substrates and templates. With appropriate process modifications, sequential deposition layers can enhance the functionality and performance of textiles.

Agricultural applications: 

Electrostatically spun materials can be used in agriculture to control the release of fertilizers, pesticides or growth regulators.These materials can also be used for crop protection, soil improvement and water management in agricultural practices.

Limitations of current electrostatic spinning technology:

Limitations of current electrostatic spinning technology include mass production, consistency, and scalability issues. There are also limitations in controlling fiber properties, environmental concerns, and cost-effectiveness. Understanding the complex dynamics of polymer behavior during electrostatic spinning remains a challenge.
