外文摘要：Electrospinning of dispersions with higher viscosity and limited flow may be carried out, based on the solvent assisted coaxial technique, where the flow of the core dispersion is supported by a free flowing sheath solvent. In the present work, the sheath solvents used are chloroform, toluene and dimethyl formamide and we discuss the fiber formation of Poly Methyl Methacrylate (PMMA) (dispersion-25 wt%). PMMA dispersed in chloroform is taken as the core solution and the sheath is pure solvent. The In-Situ effect of different sheath solvents in fiber formation at two different tip to collector distances are studied. The fibers formed are subjected to SEM analysis and the characteristics are analysed. The fiber formation of high viscos polymer dispersions makes the same materials subjectable to electrospinning and further applications.
