PLA/PAA复合纤维膜的制备及其力学性能研究
Study on the mechanical properties and preparation of PLA/PAA composite fiber films
摘要
Abstract
Polylactic acid/Acrylic acid Polymers (PLA/PAA) composite fiber films were pre-pared by electrospinning.The morphology,crystallinity and mechanical properties of the fi-ber films were examined by field-emission scanning electron microscopy (FE-SEM ),X-ray diffraction(XRD),differential scanning calorimeter (DSC) and tensile testing machine.The effects of PAA addition and the change of electric field on the crystallinity,thermal proper-ties and mechanical properties of nanofibers were investigated.As the study shows :the blending with PAA changes the crystallinity and thermal properties of PLA.When the ratio of PLA /PAA compound is 5:1,4:1,3:1,respectively and the mass percentage of the spinning solution was 8%,under 20 kV of the applied voltage and receiving distance reaching 10 cm,and with electrostatic spinning,the maximum tensile strength and tensile strength of the PLA/PAA fiber membranes are all increased in different degrees bur the elongation at break decreased.关键词
