摘要: A novel fabrication process for preparing continuous thermoplastic nanofibrillary structures by using the conventional melt spinning method of polymer fibers is developed. Poly(lactic acid) nanofibrils with average diameter 60 nm are obtained processing water soluble poly(vinyl alcohol) (PVA) and poly(lactic (PLA) blends at weight ratio 70/30 subsequent removal PVA matrix. The textile physical properties (tensile elongation properties) PVA/PLA filaments investigated interpreted. Produced 2D 3D PLA promising candidates as scaffolds tissue engineering. Using selecting “green polymer” a matrix component, this therefore provides an optimal solution to handle important scientific challenges present time: economic environmental friendly highly specialized products medical purposes.
