The aim of this work was to develop new biodegradable polymeric materials with high loadings of chicken feather (CF). In this study, the effect of CF concentration and the type of biodegradable matrix on the physical, mechanical and thermal properties of the biocomposites was investigated. The selected biopolymers were polylactic acid (PLA), polybutyrate adipate terephthalate (PBAT) and a PLA/thermoplastic copolyester blend. The studied biocomposites were manufactured with a torque rheometer having a CF content of 50 and 60 wt %. Due to the low tensile strength of CFs, the resulting materials were penalized in terms of mechanical properties. However, high-loading CF biocomposites resulted in lightweight and thermal-insulating materials when compared with neat bioplastics. Additionally, the adhesion between CFs and the PLA matrix was also investigated and a significant improvement of the wettability of the feathers was obtained with the alkali treatment of the CFs and the addition of a plasticizer like polyethylene glycol (PEG). Considering all the properties, these 100% fully biodegradable biocomposites could be adequate for panel components, flooring or building materials as an alternative to wood⁻plastic composites, contributing to the valorisation of chicken feather waste as a renewable material.
这项工作的目的是开发具有高含量鸡毛（CF）的新型可生物降解聚合物材料。在本研究中，研究了CF浓度和可生物降解基质类型对生物复合材料物理、机械和热性能的影响。所选的生物聚合物为聚乳酸（PLA）、聚己二酸丁二醇酯对苯二甲酸酯（PBAT）和PLA/热塑性共聚酯共混物。所研究的生物复合材料是用CF含量为50%和60%（重量）的转矩流变仪制造的。由于CF的拉伸强度较低，所得材料在机械性能方面受到影响。然而，与纯生物塑料相比，高负载CF生物复合材料制成了轻质且隔热的材料。此外，还研究了CF与PLA基质之间的粘附性，通过对CF进行碱处理并添加聚乙二醇（PEG）等增塑剂，鸡毛的润湿性得到了显著改善。综合考虑所有性能，这些100%完全可生物降解的生物复合材料可作为木塑复合材料的替代品，适用于面板组件、地板或建筑材料，有助于将鸡毛废料作为可再生材料加以利用。
