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 کاملcrystallization behavior of poly(l-lactide) films in presence of mg(oh)2 and l-lactide
the effects of magnesium hydroxide and l-lactide dimer as additives on thermal properties and morphology of poly(l-lactide) (plla) films were studied. hence, neat plla films and films containing additives (10% w/w) were prepared in dichloromethane at room temperature via solution casting. to evaluate thermal history on polymer properties, plla films were annealed by different processes. in one ...
متن کاملIn Vitro Degradation of Borosilicate Bioactive Glass and Poly(l-lactide-co-ε-caprolactone) Composite Scaffolds
Composite scaffolds were obtained by mixing various amounts (10, 30 and 50 weight % [wt %]) of borosilicate bioactive glass and poly(l-lactide-co-ε-caprolactone) (PLCL) copolymer. The composites were foamed using supercritical CO₂. An increase in the glass content led to a decrease in the pore size and density. In vitro dissolution/reaction test was performed in simulated body fluid. As a funct...
متن کاملVascularization Potential of Electrospun Poly(L-Lactide-co-Caprolactone) Scaffold: The Impact for Tissue Engineering
BACKGROUND Electrospun nanofibers have widespread putative applications in the field of regenerative medicine and tissue engineering. When compared to naturally occurring collagen matrices, electrospun nanofiber scaffolds have two distinct advantages: they do not induce a foreign body reaction and they are not at risk for biological contamination. However, the exact substrate, structure, and pr...
متن کاملEncapsulation and Controlled Release of Heparin from Electrospun Poly(L-Lactide-co-ε-Caprolactone) Nanofibers.
Poly(L-lactide-co-ε-caprolactone) nanofibers with heparin incorporated were successfully fabricated by coaxial electrospinning. The morphologies of electrospun nanofibers were studied by scanning electron microscopy (SEM), and a significant decrease in fiber diameter was observed with increasing heparin concentration. The transmission electron microscopy (TEM) images indicated that coaxial elec...
