“…The materials selected for the preparation of polymer blend films were a commercial poly(ethylene oxide) (PEO) powder with a number‐average molecular weight M n of 200,000 g mol −1 (Sigma Aldrich, Saint Quentin Fallavier, France) and pellets of PBSA (statistic copolyester with 80% of succinic acid ) was purchased from NaturePlast (PBE 001 reference, Caen, France). For fluorescein migration studies, PEO was formulated with fluorescein sodium salt (Sigma Aldrich, Saint Quentin Fallavier, France) as described below.…”

Varying the formulation and processing conditions of polymer blends allows the design of materials with a large range of morphologies. Active materials embedding active compounds in a devoted phase are promising applications of such blends, offering possible various transport properties. In this study, 13 poly(butylene succinate-co-butylene adipate) (PBSA)/polyethylene oxide (PEO) blends were extruded in a slit die. Their morphologies were characterized by water extraction (selective PEO dissolution), FTIR spectroscopy, and differential scanning calorimetry. Transport properties were assessed by water vapor permeation and fluorescein release as model migrant. Indeed, the desorption in water of fluorescein (previously entrapped in PEO) was monitored to preliminary investigate the release properties of these materials: two morphologies were obtained (i) pseudo multilayer films made of PEO-rich layer/ PBSA-rich layer/PEO-rich layer and (ii) PEO nodules dispersed in the PBSA-rich matrix for the highest PBSA contents. The first systems were erodible ones with an uncontrolled fast delivery by PEO dissolution whereas the second ones showed a controlled release by permeation through the PBSA matrix from PEO nodules.

Starch (PS) isolated from fresh pasta by‐product was plasticized with different amount of glycerol (10, 15, and 20%). X‐ray diffraction highlighted that after PS plasticization, the obtained bio‐films showed a partial change in the crystallinity and typical saccharide bands were put in evidence by peaks associated with C‐C, C‐O, C‐H, and ‐OH stretching from the Fourier transform infrared spectroscopy spectra. The differential scanning calorimetry measurements demonstrated that glass transition temperature (Tg) of bio‐films decreased with increasing glycerol content. In addition, their total soluble matter released in distilled water increased with increasing the glycerol content; and an increase in relative humidity and in plasticizer content resulted in the highest values of water uptake. The tensile properties revealed a significant decrease in both Young's modulus and tensile strength but an increase in elongation at break with increasing the glycerol content. The biodegradation tests proved that bio‐films were more biodegradable than the extracted starch implying a strong connection between plasticizer and biodegradability. © 2018 American Institute of Chemical Engineers Environ Prog, 38: 527–533, 2019

“…The same is true of composite plastics mixed with biodegradable materials, for instance, lDPE/starch 6 or lDPE/chitosan (sunilkumar et al, 2012;Rutkowska et al, 2002) blends that are sometimes mislabeled as "biodegradable plastics." On environmental exposure, only the starch or chitosan fraction in these will readily biodegrade, and the resulting porous recalcitrant lDPE residue crumbles into small fragments (Jbilou et al, 2013). The mn (g/mol) of the lDPE particles so produced is not reduced in the process.…”
