“…The maximum fracture stress is almost comparable to that of PET (61 MPa, [32]), although the young's modulus was one tenth~one fourth relative to that of PET (1.44 GPa, [32]). It should also be noted that the PHPm films show higher maximum fracture strain than the films of poly(L-lactic acid), although the maximum fracture stress is almost same value [33]. All PHPm films showed the yielding points at the relatively small strain of 0.02~0.03 mm/mm, reflecting the nature of incorporated soft alkylene chains.…”

“…In our study it is shown that PLLA/ PBS sponges can be promising scaffolds for neural tissue engineering. According to Shibata et al (2006), PLA/PBS blends have a higher tensile strength compared to pure PLA or PBS. It was demonstrated by Hua et al (2012) that PLA/PBS blends have good biocompatibility and result in a mild and acceptable inflammatory response when implanted in rats subcutaneously.…”

“…In addition, the degradation product of PBS is succinic acid, which is converted to CO 2 and H 2 O in the tricarboxylic acid cycle. Blending PLLA and PBS results in a lower crystallization temperature (Shibata et al, 2006). Besides, by determining a convenient composition, the blend can have high flexibility.…”

In tissue engineering, the use of poly-L-lactic acid (PLLA)/polybutylene succinate (PBS) blend for the construction of scaffold is very limited. Moreover, polymeric sponges fabricated from PLLA/PBS have not been studied for neural tissue engineering. In the present study, the potential of the utility of PLLA/PBS polymeric sponges seeded with Schwann cells was investigated. PLLA and PBS were blended in order to increase the processability and tune the crystallinity, porosity, and degradation rate of the resulted polymeric sponges. These sponges were then seeded with Schwann cells. Porosity analysis showed that there were no significant differences between different compositions of PLLA/PBS blends; however, the porosity was slightly higher in PLLA/PBS (3%, w/v, 2:1) scaffold. Degradation profiles were also investigated for 120 days and almost 25% weight of PLLA/PBS (6%, 4%, 2%, w/v, 1:1) scaffolds and 18% weight of PLLA/PBS (3%, w/v, 2:1) scaffolds were lost at the end of 120 days. In vitro cell culture studies were also performed and the results proved that all PLLA/PBS blended scaffolds were biocompatible. The highest cell proliferation was observed for PLLA/PBS (3%, w/v, 2:1) scaffolds and this construct can be considered a promising biodegradable scaffold for neural tissue engineering.

“…A recent trend for toughening PLA is to adopt degradable, renewable polymers, including starch [26,27], poly (butylene succinate) (PBS) [28,29], poly (hydroxyalkanoates) [30,31], polymerized soybean oil [32] and polyamide11 (PA11) [33]; these are fabricated from renewable resources, and upon disposal are able to degrade completely in the environment within dozens of years. Shibata et al [29] toughened PLLA by poly (butylene succinate-co-L -lactate) (PBSL) and poly (butylene succinate) (PBS); at 10 wt%, these two tougheners achieved 160% and 120% higher elongation at break, respectively. Robertson et al [32] achieved 400% and 600% increase in elongation at break and tensile toughness by using polymerized soybean oil, respectively.…”

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.
