Solid wine wastes named wine lees (WL) have been tested as cost‐advantage filler within biopolymers such as poly(3‐hydroxybutyrate‐co‐hydroxyhexanoate) and poly(3‐hydroxybutyrate‐co‐hydroxyvalerate). WL have been first characterized and subsequently mixed within the polymers through a twin‐screw extruder in different concentrations (10, 20, and 40 phr). Moreover, the role of 3‐methacryloxypropyltrimethoxysilane tested as coupling agent has been investigated within the 20 phr formulation. The obtained materials have been characterized from a thermal, mechanical, rheological, and morphological point of view through: differential scanning calorimetry, melt flow rate, tensile and creep tests, dynamic mechanical analysis, and scanning electron microscopy. Results have shown how WL can improve the biopolymers overall properties without compromising their bio‐based origin. Several micromechanical models have been exploited to extend the mechanical behavior and correlations between biocomposites properties and WL contents have been carried out. Finally, the economic analysis has shown how these biocomposites could be suitable also for large‐scale applications. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48869.

酒渣废料作为成本优势和天然填料对聚（3-羟基丁酸酯-共-羟基己酸酯）（PHBH）和聚（3-羟基丁酸酯-共-羟基戊酸酯）（PHBV）的热和机械性能的影响
固体酒废料酒糟（WL）已作为聚（3-羟基丁酸酯-共-羟基己酸酯）和聚（3-羟基丁酸酯-共聚）等生物聚合物中的成本优势填料进行了测试-羟基戊酸酯）。WL的特点是先经过表征，然后通过双螺杆挤出机以不同的浓度（10、20和40 phr）将其混合在聚合物中。此外，已在20 phr配方中研究了经测试的3-甲基丙烯酰氧基丙基三甲氧基硅烷作为偶联剂的作用。从热学，机械学，流变学和形态学的角度对获得的材料进行了表征，包括：差示扫描量热法，熔体流动速率，拉伸和蠕变测试，动态力学分析和扫描电子显微镜。结果表明，WL如何在不损害其生物基来源的情况下改善生物聚合物的整体性能。已经开发了几种微机械模型来扩展机械性能，并且已经进行了生物复合材料性能和WL含量之间的相关性。最后，经济分析表明这些生物复合材料如何也适用于大规模应用。分级为4 +©2019 Wiley Periodicals，Inc.J.Appl。Polym。科学2020，137，48869。
