“…These changes are due to the increase in the polymer chain mobility, indicating a plasticization effect. Moreover, degree of crystallinity (χ c ) of the blends decreased with increasing limonene content, due to enhanced polymer chain mobility [40] and the plasticization effect [39]. The low χ c values obtained indicate that the all films are essentially amorphous.…”

Polymers derived from renewable resources are now considered as promising alternatives to traditional petro-polymers as they mitigate current environmental concerns (raw renewable materials/biodegradability). d-limonene can be found in a variety of citrus, indeed is the main component of citrus oils and one of most important contributors to citrus flavor. The incorporation of limonene in PLA matrix was evaluated and quantified by Pyrolysis Gas Chromatography Mass Spectrometry (Py-GC/MS). Transparent films were obtained after the addition of the natural compound. Mechanical properties were evaluated by tensile tests. The effect of limonene on mechanical properties of PLA films was characterized by an increase in the elongation at break and a decrease in the elastic modulus. The fracture surface structure of films was evaluated by scanning electron microscopy (SEM), and homogeneous surfaces were observed in all cases. Barrier properties were reduced due to the increase of the chain mobility produced by the d-limonene.

“…On the other hand, this polymer has some drawbacks as well, including moisture sensitivity, fast physical ageing, poor impact resistance and relatively high price [4][5][6]. As a consequence, many attempts have been made to modify it by plasticization [7][8][9][10][11][12][13], copolymerization [14][15][16][17][18][19], blending [20,21] or by the production of particulate filled or fiber reinforced composites [11][12][13][22][23][24][25][26][27][28][29][30].…”

“…Low-molecular weight plasticizers toughened PLA moderately but this was obtained at the cost of losing stiffness [7][8][9][10][11]. Inorganic fillers such as clay improved toughness little, although enhancing stiffness obviously [12][13][14].…”

ABSTRACT. Biodegradable, biocompatible polylactide (PLA) synthesized from renewable resources has attracted extensive interests over the past decades and holds great potential to replace many petroleum-derived plastics. With no loss of biodegradability and biocompatibility, we highly toughened PLA using a novel bioelastomer (BE)-synthesized from biomass diols and diacids. Although PLA and BE are immiscible, BE particles of ~1 µm in diameter are uniformly dispersed in the matrix, and this indicates some compatibility between PLA and BE. BE significantly increased the cold crystallization ability of PLA, which was valuable for practical processing and performance. SEM micrographs of fracture surface showed a brittle-to-ductile transition owing to addition of BE. At 11.5 vol%, notched Izod impact strength improved from 2.4 to 10.3 kJ/m 2 , 330% increment; the increase is superior to previous toughening effect by using petroleum-based tougheners.
