Abstract Interfacial compatibilization is essential to generate compatible blend structures with synergistically enhanced properties. However, the effect of molecular structure on the reactivity of compatibilizers is not properly known. This study investigates the compatibilization effect of multifunctional, epoxy-based Joncryl chain extender in blends of polylactide (PLA) and polybutylene adipate-co-terephthalate (PBAT) using PLA with varying D-lactide contents and molecular weights. These PLAs were high molecular weight amorphous PLA (aPLA) with D-content of 12 mol% and semi-crystalline PLA (scPLA) grades with D-contents below 1.5 mol% at both high (h) and low (l) molecular weights. The reactivity of Joncryl… More >

Abstract In recent years, degradable materials to replace petroleum-based materials in preparing high-performance foams have received much research attention. Degradable polymer foaming mostly uses supercritical fluids, especially carbon dioxide (Sc-CO₂). The main reason is that the foams obtained by Sc-CO₂ foaming have excellent performance, and the foaming agent is green and pollution-free. In current research, Poly (butylene adipate-co-terephthalate) (PBAT), poly (lactic acid) (PLA), and other degradable polymers are generally used as the main foaming materials, but the foaming performance of these degradable polyesters is poor and requires modification. In this work, 10% PLA was added to PBAT to… More > Graphic Abstract

Abstract In this manuscript, we conveniently prepared a series of polyester-polycarbonate copolymer (PPC-P)/polybutylene adipate terephthalate (PBAT) blends that exhibit both flame-retardant properties and toughness. Piperazine pyrophosphate (PAPP), melamine phosphate (MPP) and ZnO were used as synergistic flame retardants for PPC-P/PBAT blends. The effects of synergistic flame retardants on thermal stability, combustion behavior and flame retardancy of PPC-P/PBAT blends were investigated. The results showed that when the ratio of PAPP/MPP/ZnO was 18.4:9.2:2.4, the LOI of PPC-P/PBAT composite was 42.8%, and UL-94 reached V-0 level. The results of cone calorimetry showed that the mass loss rate (MLR), the… More >

Abstract Poly(butylene adipate-co-terephthalate) (PBAT) and poly(butylene succinate-co-adipate) (PBSA) blend films were prepared with different contents of a multifunctional epoxide chain extender Joncryl ADR-4468 (ADR) or benzoyl peroxide (BPO). The long-chain-branching (LCB) introduced by ADR and branched/crosslinked entanglement induced by BPO increased melt elasticity, viscosity and compatibility, as indicated by thermal properties, rheological and morphological analyses. It was found that the elongation at break and the tensile strength were significantly improved, due to the enhancement of compatibility and the interfacial adhesion by the incorporation of ADR or BPO. The best mechanical properties were obtained in PBAT/PBSA/ADR (60/40/0.3) (A4T6A_0.3) More > Graphic Abstract

Abstract Polylactide (PLA)/poly (butylene adipate-co-terephthalate) (PBAT) blend nanocomposites including 3 wt% of cellulose nanocrystals (CNCs) were prepared by melt compounding method in a twin-screw extruder and an internal mixer. Blend nanocomposites were formulated by diluting three different masterbatches prepared by solution casting method that contained 7 wt% of CNC. These masterbatches were: (m1) PLA/PBAT/CNC masterbatch; (m2) PLA/CNC masterbatch; and (m3) PBAT/CNC masterbatch. These were to explore how different preparation methods affect the dispersion and localization of CNC and hence the properties of PLA/PBAT/CNC blend nanocomposites. Scanning electron microscopy (SEM) was used to study the structural changes… More >

Abstract Poly(lactic acid)/poly(butylene adipate-co-terephthalate) (PLA/PBAT)-based nanocomposites were prepared by melt blending of PLA and PBAT with 5 wt% of unmodified (Cloisite Na) and modified (Cloisite 30B) montmorillonites. X-ray diffraction (XRD) revealed an intercalated structure in both nanocomposites. The extent of the intercalation was higher for nanocomposites based on modified clays (OMMT) with chemical affinity with the polymer matrix. Rheological measurements have shown an increase in viscosity and a better degree of clay dispersion for nanocomposites containing OMMT. Nanocomposites with OMMT showed lower PBAT separated phase particle size and improvements in thermal stability, mechanical properties and water More >
