Electrospinning of Poly(L-lactide-co-D, L-lactide)
Electrospinning method was used to fabricate poly(L-lactide-co-D,L-lactide) (PLDLA) nanofiber non-woven membranes. The structure and morphology of the electrospun membranes were investigated by a scanning electron microscope (JEOL) after a gold coating. The diameter of the electrospun fiber was measured by Adobe Photoshop 5.0 software from the SEM pictures. SEM images showed that the fiber diam...
متن کاملSynthesis and Biodegradation of Poly(l-lactide-co-β-propiolactone)
Although the copolymerizations of l-lactide (LA) with seven- or six-membered ring lactones have been extensively studied, the copolymerizations of LA with four-membered ring lactones have scarcely been reported. In this work, we studied the copolymerization of LA with β-propiolactone (PL) and the properties of the obtained copolymers. The copolymerization of LA with PL was carried out using tri...
متن کاملNMR crystallography of α-poly(L-lactide).
A complementary approach that combines NMR measurements, analysis of X-ray and neutron powder diffraction data and advanced quantum mechanical calculations was employed to study the α-polymorph of L-polylactide. Such a strategy, which is known as NMR crystallography, to the best of our knowledge, is used here for the first time for the fine refinement of the crystal structure of a synthetic pol...
متن کاملAngiogenic and Osteogenic Coupling Effects of Deferoxamine-Loaded Poly(lactide-co-glycolide)-Poly(ethylene glycol)-Poly(lactide-co-glycolide) Nanoparticles
Angiogenesis and osteogenesis coupling processes are essential for bone regeneration, and human bone marrow stromal cells (hBMSCs) along with endothelial cells (ECs) are crucial participants. Deferoxamine (DFO), a hypoxia-mimetic agent, could activate the hypoxia-inducible factor (HIF)-1α signaling pathway and trigger angiogenic and osteogenic effects in these cells. However, the lifetime of DF...
متن کاملSolid-state microstructure of poly(l-lactide) and l-lactide/meso-lactide random copolymers by atomic force microscopy (AFM).
Tapping mode atomic force microscopy was used to investigate the lamellar morphology of poly(l-lactide) and two poly(l-lactide-co-meso-lactide) random copolymers containing 3% and 6% meso-lactide. Samples were isothermally crystallized at selected temperatures, and qualitative and quantitative analyses of lamellar structure were performed using height and phase images. This is the first study o...
