“…Likewise, the incorporation of chitosan led to higher water vapor permeability than that of neat PLA films while providing antimicrobial activity against total aerobial and coliform bacteria. PLA-Poly(butylene succinate- co -adipate) (PBSA) and Poly(butylene adipate- co -terephthalate) (PBAT) were obtained by Pivsa-Art et al [ 33 ]. From the morphological study, it was found that an 80:20 PLA-PBSA polymer blend shows a worthy distribution of components and improved mechanical properties after the addition of PBAT, as an interfacial agent, at 10–30 wt.…”

The massive use of synthetic plastics, in particular in the food packaging area, has a great environmental impact, and alternative more ecologic materials are being required. Poly(lactic) acid (PLA) and starch have been extensively studied as potential replacements for non-degradable petrochemical polymers on the basis of their availability, adequate food contact properties and competitive cost. Nevertheless, both polymers exhibit some drawbacks for packaging uses and need to be adapted to the food packaging requirements. Starch, in particular, is very water sensitive and its film properties are heavily dependent on the moisture content, exhibiting relatively low mechanical resistance. PLA films are very brittle and offer low resistance to oxygen permeation. Their combination as blend or multilayer films could provide properties that are more adequate for packaging purposes on the basis of their complementary characteristics. The main characteristics of PLA and starch in terms of not only the barrier and mechanical properties of their films but also of their combinations, by using blending or multilayer strategies, have been analyzed, identifying components or processes that favor the polymer compatibility and the good performance of the combined materials. The properties of some blends/combinations have been discussed in comparison with those of pure polymer films.

“…For example, the chain extension reaction was considered as valuable solution to increase the elongational melt properties where strain‐hardening occurred for modified PLAs with an epoxy‐based chain extender . Preparation of polymer blends using poly(butylene succinate‐ co ‐adipate) (PBSA) and poly(butylene adipate‐ co ‐terephthalate) (PBAT) to improve both mechanical and rheological properties was also studied . In earlier work, using the internal batch mixer, we evaluated the effects of (i) blending PLA with PBSA and (ii) the addition of an epoxy‐based chain extender on rheological and mechanical properties of the corresponding blends .…”

Poly(lactic acid) (PLA), a biosource, biodegradable polymer, is not suitable for some important polymer processing operations, such as film blowing and blow molding, due to its low melt strength. Moreover, while it has high tensile modulus and strength in the solid state, it exhibits low ductility. The present work is an extension of our earlier effort to improve the processability and mechanical properties of PLA by blending with poly[(butylene succinate)‐co‐adipate)] (PBSA), a biodegradable polymer with lower glass transition temperature. We evaluate the influences of incorporation of an epoxy chain extender and nanoclay on the properties of the blend. Since earlier work was conducted in a batch mixer, the influence of melt processing in the twin screw extruder and the differences between products obtained in the extruder and the batch mixer are evaluated and explained. Based on earlier work, the following PLA/PBSA blend ratios of 90:10, 80:20 and 70:30 were selected. All the samples were prepared in the twin‐screw extruder at two different screw speeds (50 and 150 rpm), to evaluate the effects of residence time and shear rates. The morphology and structure of the blends were examined using field emission scanning electron microscopy. Transmission electron microscopy (TEM) and X‐ray diffraction (XRD) were used to evaluate the levels of intercalation and exfoliation in the nanocomposites. The chain extension reaction was evaluated using nuclear magnetic resonance (NMR) spectroscopy and other techniques. Rheological properties (dynamic oscillatory shear and elongational viscosity measurements) and mechanical characteristics of the pure components, blends, and nanocomposites were studied and discussed in light of the composition and morphology of the blends and the nanocomposites. © 2015 Wiley Periodicals, Inc.

Surface wettability of thin films is significant for their functional properties. Poly(L-lactic acid) (PLLA) is proposed as film matrix for building porous topological surfaces. By controlling the dope composition and ambient conditions, the films with ordered pores at micrometer scale are obtained. The results demonstrate that the hydrophilic or hydrophobic surface can be realized by building the porous topological surfaces. Increasing polymer concentration can lead to decreased pore size. The transition behavior of surface pores from discrete bowl-like to interconnected honeycomb-like structure with the increasing humidity is observed. The contact angle of top surface of film is higher than that of bottom surface, which verified the different roughness performance. The morphology and scale of topological structure are markedly related with the template effect of water droplets. V C 2016 Wiley Periodicals, Inc. J.Appl. Polym. Sci. 2017, 134, 44572.
