Abstract

The widespread application of composite materials in diverse fields warrants the need of biocompatible materials to favor environmental sustainability and eco-friendliness. In this context, the rhizome of the lotus aquatic plant has attracted the exploration of its qualities for composite application. The Nelumbo nucifera (NN) is the botanical name of the lotus plant whose unused rhizome has been extracted, dried, crushed, and analyzed. The NN rhizome powder is characterized by Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive X-ray analysis (EDX), dynamic light scattering (DLS), and thermogravimetric analysis (TGA). The rhizome powder has hydroxyl, carboxyl, and ether functional groups with heterogeneous surface morphology, uneven dimensions particle sizes, and coarse structure. The XRD and TGA test reported the crystalline nature of the rhizome powder with CI 57.7%, crystallite size of 2.2 nm, and thermal stability up to 290 °C. These characteristics and results extend the NN rhizome as a natural filler in polymer composites with enhanced biological sustenance.

基于海带生物质废物的生物填料：用作可生物降解填料的综合特性分析

随着复合材料在各个领域的广泛应用，人们需要具有生物兼容性的材料，以促进环境的可持续性和生态友好性。在此背景下，荷花水生植物的根茎吸引了人们对其复合材料应用品质的探索。Nelumbo nucifera（NN）是荷花的植物学名称，其未使用的根茎已被提取、干燥、粉碎和分析。傅立叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）、X 射线衍射（XRD）、能量色散 X 射线分析（EDX）、动态光散射（DLS）和热重分析（TGA）对 NN 根茎粉进行了表征。根茎粉末具有羟基、羧基和醚官能团，表面形态不均匀，粒度不均，结构粗糙。XRD 和 TGA 测试表明，根茎粉具有结晶性，CI 为 57.7%，结晶尺寸为 2.2 nm，热稳定性高达 290 ℃。这些特性和结果拓展了根茎作为天然填料在聚合物复合材料中的应用，增强了生物营养。
