The effect of solvents system, medium cooling, syringe heating on electrospinning of supramolecular polycaprolactone

In this study the electrospinning of supramolecular polycaprolactone with oligomers that self-assembled through non covalent interactions has been investigated. In supramolecular polymers the properties of the fibres produced are subject to changes in solvent, concentration and temperature. the effect of solvents system, supramolecular interactions weakening, medium cooling and these factors altogether, on fibers or droplets morphology have been studied. For solvent systems based on choloroform/dimethyl formamide/acetic acid with increasing DMF content and thus increasing dielectric constant an enhance in fiber formation was observed. On the other hand Syringe heating or medium cooling have clear effect on fibers morphology and in some solvent systems led to tailed droplets or short fibrils formation
