“…451 PLA-OLA films showed a single step degradation process 452 in all cases, with T max values similar to those of the neat 453 polymer, which was 365°C, in agreement with previously 454 reported values [11,31,32]. However, the thermal stability 455 of these materials was reduced by the addition of OLAs.…”

“…On the basis of the micrographs it can be inferred that the presence of the compatibilizers in the ternary blends leads to a finer PE dispersed phase and improves the adhesion between PLA and PE due to reactions between PLA functional end-groups and the GMA groups present in both compatibilizers [13,17] . These reactions may be favored by molecular weight reduction that occurs during processing, thereby increasing the number of PLA end-groups [18,19] . The compatibilizers also have affinity with the polyethylene due to the presence of ethylene blocks in their structures.…”

Abstract:In this work, Polylactide/Biopolyethylene blends were developed. Although some studies have been carried out on polylactide/polyethylene blends, none of them has used polyethylene synthesized with raw material obtained from natural sources. Due to the incompatibility between polylactide and polyethylene, E-GMA and EMA-GMA compatibilizers were used. These compatibilizers present glycidyl methacrylate groups in their structure, which may react with the functional end-groups of polylactide. To evaluate the properties, the blends were characterized by mechanical tests, scanning electron microscopy (SEM) and melt flow index (MFI). The results indicated that the compatibilizers played an important role in the blends, interacting with the blends components, modifying the morphology and improving the mechanical properties.

“…Both SiV AM -PLA and CC-PLA showed a peak at 16°, which was assigned to the diffraction peak from the crystalline part of PLA. 16), 17) The SiV AM and SiV AM -PLA particles were estimated to contain 2.0 and 1.6 wt % of silicon, respectively, from the ICP-AES analysis. To achieve insight into the structure of these trace amounts of APTES-derived siloxane, 29 Si CP/MAS-NMR was performed on the particles (Fig.…”

Siloxane-containing vaterite (SiV) particles with red-blood-cell-like morphologies were prepared by a CO 2 gas carbonation process for application as osteogenic devices in bone tissue engineering. The particles release soluble silica species and calcium ions, which are expected to genetically stimulate osteoblasts to enhance bone reconstruction. The released particles possessed the mean diameter of 2¯m¯with the thickness of approximately 0.7¯m. The BrenauerEmmettTeller surface area was estimated to be 76 m 2 ·g ¹1 . In addition, the shape of the nitrogen adsorptiondesorption hysteresis of the particles indicated the presence of slit-or wedge-shaped mesoporous structures. The particles were primarily composed of vaterite with aminopropyl-functionalised siloxanes in the silicon mass percentage of approximately 2 wt %. Soluble silica species and a trace amount of calcium ion were released into the physiological pH buffer solution (pH 7.4) during the initial 1 h of soaking. To estimate its potential for loading functional molecules, polylactide (PLA) was used as the model molecule and the SiV particles were prepared in their presence. Fourier transform infrared spectrometry of the sample revealed that PLA formed a carboxylate salt with the calcium ions and was loaded into the mesoporous structures. Upon contact with the buffer solution, the calcium-salt PLA and siloxane were released simultaneously within the initial 1 h of soaking.
