Summary: The effect of lactic acid grafted starch nanocrystals (g-SNCs) on the soil burial degradation rate of Poly (lactic acid) (PLA) was studied. The results showed that the addition of g-SNCs nanoparticles accelerated the degradation rate of PLA. Furthermore, the chemical bonds and material structure of PLA/g-SNCs changed after soil burial.

Summary: The addition of L-LA into PLLA scaffold promoted its degradation rate by weakening intermolecular forces and introducing hydrophilic functional groups, leading to reduced crystallinity and increased weight loss. The scaffold also exhibited good cytocompatibility for cell adhesion and growth with enhanced cell numbers and adhesion area over time.

Summary: In this research, a hydroxyapatite-Al2O3 reinforced poly (lactic acid) hybrid coating was synthesized on magnesium to improve interface strength, corrosion properties, and dissolution rate. The coatings were produced using the spin-coating technique of the synthesized solutions. The characterization, mechanical properties, and in-vitro bioactivity of the hybrid coatings were investigated.

Summary: The production of biocompatible composite scaffolds using additive manufacturing is growing in popularity. This study focuses on the effects of different grades of polymers and the addition of hydroxyapatite (HAp) on the degradation behavior and thermal stability of the scaffolds. The results show that a higher HAp content slows down the degradation of the polymer and improves its thermal stability, as evidenced by morphological changes and differences in glass transition temperatures throughout the samples.

Summary: In this study, three bio-based flame-retardant plasticizers derived from l-lactic acid and phosphorus-containing monomers were synthesized and their effects on PLA resin were investigated. The additives improved the flame retardancy and mechanical properties of PLA while maintaining excellent optical transparency. Thus, they have the potential to be green options for future electronic products.

Summary: A random terpolymer was used to improve the foaming behavior of poly (lactic acid) (PLA) through chain extension reaction, forming a branched/micro-crosslinked structure to enhance the crystallization properties and dynamic rheological behavior of PLA. Increasing the content of EGMA accelerated crystal nucleation and growth rate of PLA, resulting in reduced cell size and increased cell density of PLA foams.

Summary: The anisotropic hierarchical structures of naturally derived materials have been used as design principles to fabricate high-strength and functional materials. In this study, a structure-by-bionics approach was used to create pea pod-mimicking architecture for poly(lactic acid) (PLA) composites incorporated with hydroxyapatite nanowhiskers (HANWs). The resulting structured PLA composites showed improved mechanical properties and bioactivity, making them promising for guided bone/tissue regeneration therapy.
