Electrospining Machine: Materials Today Review: Advances in Nanofiber Membrane at Liquid-Liquid and Solid-Liquid Interfaces by Sai Ram Fellows

Background

A membrane is a thin layer or sheet at the interf

ace of two material chambers used in separation and purification processes. Membranes made using Electrospun Nanofbers are known as nanomembranes. In electrospinning machine technology, electrospinning is an industrially viable method of preparing Nanofiber Membrane due to its adjustable performance and economy.Nanofiber Membrane has received a lot of Nanofiber Membrane

A recent review by Fellow Sai Ram and others at the National University of Singapore focuses on the use of Nanofiber Membrane in various applications, surface modification techniques and the potential for innovation in this field. The review, entitled ‘Electrospun nanomembranes at the liquid-liquid and solid-liquid interface - a review’, was published in the journal Materials Today. The article was published in the journal ‘Materials Today’ ( IF 24.2 ).

The main point of this paper

1.This paper reviews techniques for modifying Nanofiber Membrane by post-treatment, coating, additives, interfacial polymerisation, surface chemistry control, pore size and porosity control, hydrophobicity/hydrophilicity and flux retention efficiency at liquid-liquid and solid-liquid interfaces.

2.ENMs in desalination, textile wastewater remediation, agriculture, biomedicine, renewable energy, electrical and food industries were also investigated.

3.The potential of ENM in liquid gating, which has been ranked as one of the top ten emerging technologies, is reviewed. This review also identifies areas where ENM needs to be innovative and sustainability aspects of electrospinning technology.
