Toughening of biodegradable polylactide/poly(butylene succinate-co-adipate) blends via in situ reactive compatibilization.
Polylactide and poly(butylene succinate-co-adipate) (PLA/PBSA) were melt-blended in the presence of triphenyl phosphite (TPP). An increase in the torque during melt mixing was used to monitor the changes in viscosity as compatibilization of the blends occurred. Scanning electron micrographs showed not only a reduction in the dispersed-phase size with increased TPP content but also fibrillated l...
متن کاملBiodegradable polylactide/montmorillonite nanocomposites.
Our continuing research on the preparation, characterization, materials properties, and biodegradability of polylactide (PLA)/organically modified layered silicate (OMLS) nanocomposites has yielded results on PLA/montmorillonite nanocomposites. Montmorillonite (mmt) modified with dimethyldioctadecylammonium cation was used as an OMLS for nanocomposite preparation. The internal structure of nano...
متن کاملFeasibility of Using Multilayer Platelets as Toughening Agents
It is known that the toughness of brittle ceramics can be improved significantly with the addition of hard platelets. In the present study, platelet-shape multilayer ceramic laminates are utilized as a toughening agent for alumina ceramics. They are prepared by laminating the BaTiO3-based ceramic tapes. Although the elastic modulus of the BaTiO3based platelets is lower than that of the alumina ...
متن کاملSynthesis of Polylactide-grafted Dextran and Their Application as Biodegradable Biomedical Materials
Biodegradable, biocompatible polymers are of interest for use in several biomedical and pharmaceutical applications. Based on its biodegradability, biocompatibility, high mechanical strength, and good shaping and molding properties, polylactide (PLA) is frequently utilized as an implantable carrier for drug delivery systems, as well as a surgical repair material. However, its high crystallinity...
متن کاملGrafting Modification of the Reactive Core-Shell Particles to Enhance the Toughening Ability of Polylactide
In order to overcome the brittleness of polylactide (PLA), reactive core-shell particles (RCS) with polybutadiene as core and methyl methacrylate-co-styrene-co-glycidyl methacrylate as shell were prepared to toughen PLA. Tert-dodecyl mercaptan (TDDM) was used as chain transfer agent to modify the grafting properties (such as grafting degree, shell thickness, internal and external grafting) of t...
