In this study, peppermint ( L.), German chamomile ( L.) and yarrow ( L.) were applied as natural fibrous fillers to create biocomposites containing substances of plant origin. The purpose of the work was to investigate the activity and effectiveness of selected plants as a material for the modification of natural rubber composites. This research was the first approach to examine the usefulness of peppermint, German chamomile and yarrow in the field of polymer technology. Dried and ground plant particles were subjected to Fourier transmission infrared spectroscopy (FTIR) and UV-Vis spectroscopy, thermogravimetric analysis (TGA), goniometric measurements (contact angle) and scanning electron microscopy (SEM). The characterization of natural rubber composites filled with bio-additives was performed including rheometric measurements, FTIR, TGA, cross-linking density, mechanical properties and colour change after simulated aging processes. Composites filled with natural fillers showed improved barrier properties and mechanical strength. Moreover, an increase in the cross-linking density of the materials before and after the simulated aging processes, compared to the reference sample, was observed.
在本研究中，薄荷（唇形科）、德国洋甘菊（菊科）和蓍草（菊科）被用作天然纤维填料，以制备含有植物源物质的生物复合材料。这项工作的目的是研究所选植物作为天然橡胶复合材料改性材料的活性和有效性。本研究是在聚合物技术领域考察薄荷、德国洋甘菊和蓍草实用性的首次尝试。对干燥并研磨后的植物颗粒进行了傅里叶透射红外光谱（FTIR）、紫外可见光谱、热重分析（TGA）、测角测量（接触角）和扫描电子显微镜（SEM）分析。对填充有生物添加剂的天然橡胶复合材料进行了表征，包括流变测量、FTIR、TGA、交联密度、力学性能以及模拟老化过程后的颜色变化。填充有天然填料的复合材料表现出改善的阻隔性能和机械强度。此外，与参考样品相比，观察到模拟老化过程前后材料的交联密度有所增加。
