Role of Macromolecular Factor in Polymer Solution Electrospinning Process

Resumo

The problems associated with theoretical concepts of electrospinning and determination of the influence of macromolecular factor (precisely molecular mass), molecular mass distribution, chain flexibility, and solution quality on electrospinning are studied. This concept is pitted against the previously known theory supporting decisive influence of electrophysical properties of solutions without regard for the nature of the dissolved substances, including polymers. The domestic and foreign works confirming the chosen concept are reviewed. Various empirical models that allow prediction of transition of electrospraying process to process of electrospinning of defect-free fibres are proposed.
