“…The PBAT, present in the greater quantity of the composition, wrapped the PLA, which assumed the fibrillar form inside the material. At the surface, It is possible to identify the PLA and PBAT domains the poor adhesion and a well‐defined separated interface between them by formation of pores, indicated by an arrow in Figure (a), also present in the cross‐section image [Figure (b)], which is likely to reduce blend properties. In Figures (c–f), the samples 66 PBAT 24 PLA 10 C and 56 PBAT 24 PLA 20 C , unlike the neat blend, demonstrated an improved interface between the polymers; in other words, there was less phase segregation between PBAT and PLA, indicating that CaCO 3 affects blend compatibility .…”

The use of flexible films in agriculture has increased intensely in the last 15 years bringing benefits to producers. However, environmental impacts increased due to their incorrect post‐use disposal which leads the degradable films to emerge as an alternative. The production films of poly(butylene adipate‐co‐terephthalate) and poly(lactic acid) reinforced with calcium carbonate (CaCO3) was studied focusing on producing lower cost materials and flexible films. Four different films (reinforcement compositions) were prepared by melt extrusion with 10 and 20 wt % of CaCO3. Mechanical and thermal properties, crystallinity, water absorption, and soil degradation, were evaluated. The addition of reinforcement leads to improved compatibility between the polymers in the matrix, which usually presented phase segregation. The films showed better mechanical properties with the addition of CaCO3. Highly orientated amorphous structures were obtained leading to low water absorption and low degradation in the simulated soil. This low degradation, suggests that the obtained films would be of interest in flexible mulch films manufacturing, particularly for Muridori plantation system, where long‐term plantations are needed. © 2018 Wiley Periodicals, Inc.

“…Numerous works had shown that the dispersion of particles can improve the properties of the immiscible blend (23)(24)(25). Moustafa et al (24) showed that organoclay modification by toxicity-free expanded rosin (ROC) or stearic acid (SOC) enhanced the biocompatibility of PLA/PBAT blends.…”

Biodegradable nanocomposites were prepared by melt blending biodegradable poly(lactic acid) (PLA) and poly(butylene adipate-co-butylene terephthalate) (PBAT) (70/30, w/w) with diatomite or talc (1–7%). From the SEM test, the particles were transported to the interface of two phases, which acted as an interface modifier to strengthen the interfacial adhesion between PLA and PBAT. Talc and diatomite acted as nucleating agents to improve the crystallization of PBAT in the blends by DSC analysis. Moreover, adding the particles improved the tensile and impact toughness of the blends. The elongation at break with 5% talc was 78% (vs ∼21%) and the impact strength was 15 kJ/m2 (vs ∼6.5 kJ/m2). The rheological measurement revealed that the talc and diatomite reduced the viscosity of the blends. The results showed a good possibility of using talc- and diatomite-filled PLA/PBAT blends with high toughness for green-packaging and bio-membranes application.

“…Melt‐blending PLA in an extruder with other flexible polymers is an excellent method to modify PLA. Poly(lactide acid) was blended with ductile modifiers such as poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate), poly(ε‐caprolactone), poly(butylenes succinate), and poly(butylene adipate‐co‐terephthalate) (PBAT) to make fully bio‐based and/or biocompostable materials.…”

Biodegradable poly(lactic acid) (PLA)/poly(butylene adipate‐co‐terephthalate) (PBAT) blends and films were prepared using melt blending and blowing films technique in the presence of chain extender‐Joncryl ADR 4370F. The ADR contains epoxy functional groups and used as a compatibilizer. The morphological, mechanical, rheological, thermal, and crystalline properties of the PLA/PBAT/ADR blown films were studied. Scanning electron microscopy micrographs of the films revealed more ductile deformation with increasing PBAT content. The addition of PBAT enhanced the toughness of the PLA film. Tensile tests indicated that the elongation at break increased from 20.5% to 334.6% in the machine direction and from 7.1% to 715.9% in the transverse direction. The Young modulus increased from 2690.5 to 395.6 MPa in the machine direction and from 2623.5 to 154.0 MPa in the transverse direction. The sealing strength of 40/60/0.15 PLA/PBAT/ADR film was the highest among all the samples up to 9.4 N 15 mm−1. These findings gave important implications for designing and manufacturing polymer packaging materials.
