“…Different results were observed in our previous study [23] in which DEA with lower molecular weight promoted greater values of elongation of break than DIA. Xiong et al [21] and Xiong et al [33] evaluated the effects of plant oils such as Tung oil anhydride and epoxidized soybean oil as plasticizers in PLA/TPS blends containing approximately 60% of PLA and reported a decrease in the tensile strength and an increase in the elongation at break of the blends.…”

Poly(lactic acid)/thermoplastic starch sheets: effect of adipate esters on the morphological, mechanical and barrier properties

SbstractBlends of poly(lactic acid) (PLA) and thermoplastic starch (TPS) plasticized with adipate esters (diisodecyl adipate and diethyl adipate) having different molecular weight were used to produce sheets. The calendering-extrusion process at a pilot scale was used, and the mechanical, barrier, and morphological characterization of the obtained materials were performed. The increase in the TPS content affected the mechanical properties of the sheets by increasing the elongation and decreasing the rigidity. TPS conferred a more hydrophilic character to the sheets, as observed from the water vapor permeability results. The sheets plasticized with diisodecyl adipate (DIA), having a higher molecular weight, had better mechanical and barrier properties than diethyl adipate (DEA) plasticized sheets, indicating that DIA was more effective as plasticizer. Micrographs obtained by confocal laser microscopy and scanning electron microscopy showed different morphologies when different proportions of PLA and TPS were used (dispersed or co-continuous structures), which were strongly associated with the mechanical and barrier properties.

“…Although previous studies [24][25][26] have been devoted to preparing various modified starches to increase its hydrophobicity by using this method, their interest was only focused on modifying the surface of starch granules, thus the starch still exists in the form of rigid granules after melt-blending with PLA. However, to the best of our knowledge, very little work has been done to prepare TPS by chemical modification without using any plasticizer, in particular, no literatures have considered the thermoplasticity of the chemically modified starch.…”

“…Blending PLA with thermoplastic starch (TPS) can reduce the material cost, improve the gas barrier properties, and increase the biodegradation rate. However, PLA/starch composites are extremely brittle because of their coarse structure and lack of interfacial adhesion [1,[3][4][5][6][7][8].…”

Adipate and Citrate Esters as Plasticizers for Poly(Lactic Acid)/Thermoplastic Starch Sheets

et al. 2014

View full text Add to dashboard Cite

Poly(lactic acid) (PLA) and thermoplastic starch (TPS) sheets plasticized with different adipate and citrate esters were produced by a calendering-extrusion process. The incorporation of plasticizers significantly reduced the glass transition temperature and increased the PLA chain mobility thus improving the mechanical properties. Among the plasticizers employed, diethyl adipate significantly increased the elongation of the sheets and slightly increased the water vapor permeability. Micrographs revealed the incompatibility between starch and PLA, and there was no plasticizer phase separation, suggesting that the plasticizer concentration was adequate. The incorporation of adipate or citrate esters improves the mechanical properties and processability of PLA/TPS sheets produced by calendering extrusion at a pilot scale.
