Effect of plasticizer and load on melt electrospinning of PLA

摘要：

　　Melt electrospinning was used to produce PLA superfine fibers.The high spun temperature will lead to serious degradation of PLA.To alleviate the thermal decomposition and obtain superfine fibers at low temperature,sucrrose fatty acid esters (SE) was added to decrease the viscosity of PLA melt.The diameter of PLA including SE was 1.5μm while those of pure PLA was 6.4μm.At the same time,pure PLA melt cost a long time to flow out of cylinder.So SE increased the flowability of PLA melt,which ensured PLA fibers of small diameters were get at low temperature.Spinning load or melt velocity has a direct effect on the relative molecular mass of PLA fibers.
