crystallization 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 ...

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...

Plasticization of poly (L-lactide) bioplastic films with poly (propylene glycol)-b-oligo (-caprolactone)

Liquid -caprolactone (CL) oligomers were synthesized by a ring-opening reaction of CL using a propylene glycol (PPG) as the initiator for use as new plasticizers of poly (L-lactide) (PLA) films. PPG-CL oligomers containing two (PPG-2CL) and four (PPG-4CL) units of CL at both PPG end-chains were prepared. The PLA/oligomer blend films were prepared by solution blending before film casting. The t...

Surface Hydrophilicity of Poly(L-Lactide) Acid Polymer Film Changes the Human Adult Adipose Stem Cell Architecture

Current knowledge indicates that the molecular cross-talk between stem cells and biomaterials guides the stem cells’ fate within a tissue engineering system. In this work, we have explored the effects of the interaction between the poly(L-lactide) acid (PLLA) polymer film and human adult adipose stem cells (hASCs), focusing on the events correlating the materials’ surface characteristics and th...

NMR 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...
