“…The increment of mechanical properties of the PLA-PEG/MgSiO 3 membrane could be related to the filler reinforcement and strong interfacial adhesion between the PLA-PEG matrix and MgSiO 3 . This is because MgSiO 3 has a large surface area that eventually helps in the better transfer of stress through the shear mechanism from the membrane matrix to the filler, thus resulting in effective load transfer [31,32]. In addition, an improvement in the interfacial adhesion between the PLA-PEG matrix and MgSiO 3 , as can be observed in the next morphology section, is also effective in transferring the stress during breaking, as well as propagation of cracks [33].…”

In this work, the effect of magnesium silicate (MgSiO3) as a filler on poly(lactic acid)-poly(ethylene glycol) (PLA-PEG) membrane was investigated towards the enhancement of adsorption capacity for removal of cationic dye. The preparation and fabrication of membranes were performed through copolymerization and phase inversion techniques. Analysis of functional groups, tensile strength, morphology and surface wettability were employed in the characterization of the membranes. After the addition of MgSiO3, it was found that the PLA-PEG/MgSiO3 membrane presented a higher hydrophilic property with improved mechanical strength. Next, the adsorption of methylene blue (MB) was optimized using response surface methodology (RSM) with the parameters mass of membrane and initial concentration of MB solution. The effects of pH and ionic strength were also examined to determine the mechanism involved during adsorption processes, which later were found to be electrostatic interaction and ion-exchange mechanism. From the isotherms and kinetics studies, the PLA-PEG/MgSiO3 membrane was well fitted by the Freundlich model and pseudo second order model, respectively. This membrane also demonstrated reusable character of up to six cycles.

“…However, due to the non-polari NRs, PLA/NR blends are immiscible and not compatible. To improve the interfacial i action between PLA and NR, the reactive compatibilizer PLA-g-MA is used to form a copolymer PLA-g-NR [44,45]. Typically, the compatibilized blend is made in a twin sc extruder at a temperature between 160 and 180 °C and a screw speed of around 30 With the addition of PLA-g-MA, the mechanical properties of the material were sig cantly improved.…”

Poly(Lactic Acid)-Based Graft Copolymers: Syntheses Strategies and Improvement of Properties for Biomedical and Environmentally Friendly Applications: A Review

et al. 2022

As a potential replacement for petroleum-based plastics, biodegradable bio-based polymers such as poly(lactic acid) (PLA) have received much attention in recent years. PLA is a biodegradable polymer with major applications in packaging and medicine. Unfortunately, PLA is less flexible and has less impact resistance than petroleum-based plastics. To improve the mechanical properties of PLA, PLA-based blends are very often used, but the outcome does not meet expectations because of the non-compatibility of the polymer blends. From a chemical point of view, the use of graft copolymers as a compatibilizer with a PLA backbone bearing side chains is an interesting option for improving the compatibility of these blends, which remains challenging. This review article reports on the various graft copolymers based on a PLA backbone and their syntheses following two chemical strategies: the synthesis and polymerization of modified lactide or direct chemical post-polymerization modification of PLA. The main applications of these PLA graft copolymers in the environmental and biomedical fields are presented.
