Biodegradable Poly

In this study, biodegradable poly(butylene succinate)/poly(lactic acid) (PBS/PLA) in-situ submicrofibrillar composites with various PLA content were successfully produced by a triple-screw extruder followed by a hot stretching−cold drawing−compression molding process. This study aimed to investigate the effects of dispersed PLA submicro-fibrils on the thermal, mechanical and rheological properties of PBS/PLA composites. Morphological observations demonstrated that the PLA phases are fibrillated to submicro-fibrils in the PBS/PLA composites, and all the PLA submicro-fibrils produced seem to have a uniform diameter of about 200nm. As rheological measurements revealed, at low frequencies, the storage modulus (G’) of PBS/PLA composites has been increased by more than four orders of magnitude with the inclusion of high concentrations (15 wt % and 20 wt %) of PLA submicro-fibrils, which indicates a significant improvement in the elastic responses of PBS melt. Dynamic Mechanical Analysis (DMA) results showed that the glass transition temperature (Tg) of PBS phase slightly shifted to the higher temperature after the inclusion of PLA. DSC experiments proved that fiber morphology of PLA has obvious heterogeneous nucleation effect on the crystallization of PBS. The tensile properties of the PBS/PLA in-situ submicrofibrillar composites are also improved compared to neat PBS.

The Impact

The advanced development of biocomposites made of biodegradable polymers and natural fibers has initiated great interest because the resultant polymer will degrade absolutely and will not emit toxic substances. Among the biodegradable polymers, the poly(butylene succinate) and poly(lactic acid) have diverse commercial applications and the natural fiber such as wood flour is renewable and cheaper alternative to synthetic fiber. The properties of the composite made of poly(butylene succinate)/poly(lactic acid) blend and wood flour are not compatible due to the poor wettability and interfacial adhesion. Therefore, in the study presented, the Fusabond MB 100 D has been used to improve the interfacial bonding between poly(butylene succinate)/poly(lactic acid) blend and the dispersed wood flour. The results reveal that the addition of FB not only increases the tensile strength but also improves the impact strength of poly(butylene succinate)/poly(lactic acid)wood flour composite under high dynamic loading. Moreover, when Fusabond MB 100 D is added as a coupling agent to the poly(butylene succinate)/poly(lactic acid)wood flour composite results of X-ray photo spectroscopy, fracture surface morphology and dynamical mechanical property indicate the interaction between the poly(butylene succinate)/poly(lactic acid) blend with the wood flour.

Physical And Chemical

Abstract Poly(butylene succinate) (PBS) has good impact strength and high elongation at break. It is used to toughen biodegradable poly(lactic acid) (PLA) materials because it can considerably improve the toughness of PLA without changing the biodegradability of the materials. Therefore, this approach has become a hotspot in the field of biodegradable materials. A review of the physical and chemical modification methods that are applied to improve the performance of PLA/PBS blends based on recent studies is presented in this article. The improvement effect of PLA/PBS blends and the addition of some common fillers on the physical properties and crystallization properties of blends in the physical modification method are summarized briefly. The compatibilizing effects of nanofillers and compatibilizing agents necessary to improve the compatibility and toughness of PLA/PBS blends are described in detail. The chemical modification method involving the addition of reactive polymers and low-molecular-weight compounds to form cross-linked/branched structures at the phase interface during in situ reactions was introduced clearly. The addition of reactive compatibilizing components is an effective strategy to improve the compatibility between PLA and PBS components and further improve the mechanical properties and processing properties of the materials. It has high research value and wide application prospects in the modification of PLA. In addition, the degradation performance of PLA/PBS blends and the methods to improve the degradation performance were briefly summarized, and the development direction of PLA/PBS blends biodegradation performance research was prospected.
