Electrospining Machine: How to design PVA-based Electrospun Nanofbers pads with desired morphology?

Background

Poly(vinyl alcohol) is one of the most widely used polymeric materials because of its water solubility, biocompatibility, low toxicity, good mechanical properties, and relatively low cost. The researchers have published a review highlighting recent advances in the electrostatic spinning of poly(vinyl alcohol) and summarizing the process parameters (voltage, distance, flow rate, and collector), solutions (molecular weight and concentration), and environments (humidity and temperature) in order to understand the effects on the structural, mechanical, and chemical properties of poly(vinyl alcohol)-based electrospun matrices. The results were presented under the title “PVA-Based Electrospun Materials-A Promising Route to Designing Nanofiber Mats with Desired Morphological Shape The results were published in International Journal of Molecular Sciences under the title of “PVA-Based Electrospun Materials-A Promising Route to Designing Nanofiber Mats with Desired Morphological Shape”.
