“…The matrix was melt-blended with each of the fillers at the weight percentages shown in Table 15 . Although there are several polymer composites processing technique [8] , [9] , [10] , [11] , the melt-blending technique was used because it is environmentally benign, cost-effective, best for mass production, toxin-free [12] and allows for the addition of higher weight per cent of fillers. The weight per cent formulation of the fillers was obtained from the mass of the fillers ( Table 15 ) according to Eq.…”

Polylactide (PLA), a biopolymer, was reinforced with three fillers (two organic reinforcements and one inorganic filler). The processing technique used to fabricate the composites was the melt-blending technique. The composites and the unreinforced PLA were subjected to microhardness, compression and biodegradation characterisations. Data obtained are presented in this article as raw data. Data from microhardness and compression tests were used to predict the fracture toughness. The biodegradation of the composites was also examined, and the data obtained reported in this article. The data presented in this article allow for a comprehensive understanding of the mechanical behaviour and the biodegradation profile of three composites of PLA with respect to their applications as biodegradable implants. It also helps in the selection of fillers for biopolymers such as PLA.

“…Therefore, toughening is a perennial topic of PLA modifications. [1][2][3] Renewable polymers including poly (butylene succinate) (PBS), 4,5 poly (butyleneadipate-co-terephthalate) (PBAT), [6][7][8] poly (butylene succinate-co-butylene adipate) (PBSA), 9 nature rubber (NR), [10][11][12] poly (butylene 2,5-furan dicarboxylate) (PBF) 13 have been utilized to toughen PLA. The elongation at break of the PLA blend can be increased significantly; however, the enhancement of the impact strength is limited due to the poor interfacial adhesion.…”

Reactive interfacial compatibilization is the most efficient way to prepare super-tough poly (lactic acid) (PLA) materials. Introducing a post-reactive group into a toughening agent that can react with PLA is the key issue. Herein, we reported a series of fully bio-based polyesters (PBSePM) synthesized with sebacic acid, diethyl malate, 1,3-propanediol, and 1,4-butanediol via transesterification in one pot. Super-tough PLA materials can be obtained by reactively blending with PBSePM in the presence of hexamethylene diisocyanate (HDI). In the processing, the side hydroxyl group of the PBSePM reacted with HDI and formed polyurethane elastomer to improve the toughness of PLA.Moreover, the in-situ formed PLA-g-PBSePM grafted copolymer enhanced the interfacial adhesion. With increasing diethyl malate moiety in PBSePM, the PBSePM phase morphology transformed from co-continuous phase structure to semi-continuous and "sea-island" phase structure. When adding 20 wt% PBSePM, all PLA/PBSePM blends have a notched impact strength higher than 53 kJ m À2 , suggested a super toughness effect. Maximum impact strength of 83 kJ m À2 was realized while the PBSePM containing 20% diethyl malate moiety. In addition, super-tough PLA materials can be achieved by only adding 15 wt% PBSePM20, exhibited a highly efficient toughening effect.
