In this work, the miscibility of blends of thermoplastic Achira Starch (AS) and polylactic acid (PLA) was evaluated, assisted by Pluronic® F127 an amphiphilic triblock copolymer that acts as a surfactant and promotes the reduction of surface tension among AS and PLA in solution by emulsion stabilization. Different formulations of AS/PLA blends were obtained at 75:25, 50:50, and 25:75 containing 0 %, 4 %, and 8 % of Pluronic® F127, and glycerol was used as a plasticizer. Solvent casting was the method used to obtain blended polymeric films, which were characterized by Scanning Electron Microscope (SEM), Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), Thermogravimetric Analysis (TGA), differential scanning calorimetry (DSC) and wettability by contact angle measurements. The results demonstrate that miscibility of PLA in AS or vice versa was achieved. The stability of emulsion and posterior drying of the different formulations allows the production of films for packaging, pharmaceutical, or biomedical applications.

在这项工作中，在 Pluronic® F127 的辅助下，评估了热塑性 Achira 淀粉 (AS) 和聚乳酸 (PLA) 共混物的混溶性，这是一种两亲性三嵌段共聚物，可作为表面活性剂并促进 AS 和 PLA 之间的表面张力降低。通过乳液稳定溶液。获得了 75:25、50:50 和 25:75 的不同配方的 AS/PLA 共混物，其中包含 0%、4% 和 8% 的 Pluronic® F127，并使用甘油作为增塑剂。采用溶剂浇铸法获得共混聚合物薄膜，通过扫描电子显微镜（SEM）、傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）、热重分析（TGA）、差示扫描量热法（DSC）对其进行表征) 和通过接触角测量的润湿性。结果表明实现了 PLA 在 AS 中的混​​溶性，反之亦然。乳液的稳定性和不同配方的后干燥允许生产用于包装、制药或生物医学应用的薄膜。
