Abstract

Abstract Natural fibre composites are widespread for being eco-friendly and having unique properties. This study prepared nanocomposites by water evaporation using cellulose nanofibres (CNFs) as fillers and natural rubber (NR) latex as the matrix. Here, CNFs were extracted from the “pineapple fruit residue,” a waste material in juice industries. These fibre-reinforced nanocomposites were prepared under three different weight/volume percentages (5%, 10%, and 15%) and analysed for their mechanical and thermal properties. Furthermore, the morphology and distribution of CNFs in the NR matrix were examined by scanning electron microscopy and Fourier transform-infrared (FT-IR) analysis. The study found that CNFs were randomly oriented and evenly distributed in the nanocomposite. CNFs were detected by FT-IR spectroscopy in the NR matrix, as indicated by absorption peaks at 1,033 and 1,057 cm−1. Thermogravimetric analysis reveals increased thermal stability with more CNFs. Tensile strength and elastic modulus also increase. Pineapple fruit residue-based CNFs enhance mechanical and thermal properties of NR composites and can be considered an ideal natural reinforcing material.

菠萝果渣基纳米纤维复合材料:制备与表征

摘要天然纤维复合材料因其环保性和独特性能而得到广泛应用。本研究以纤维素纳米纤维（CNFs）为填料，天然橡胶（NR）胶乳为基体，通过水蒸发法制备了纳米复合材料。在这里，CNFs是从“菠萝果渣”中提取的，这是果汁行业的一种废料。这些纤维增强纳米复合材料在三种不同的重量/体积百分比（5%、10%和15%）下制备，并分析其机械和热性能。此外，通过扫描电子显微镜和傅里叶变换红外光谱（FT-IR）分析，研究了CNFs在NR基体中的形态和分布。研究发现，CNFs在纳米复合材料中呈随机取向，分布均匀。通过FT-IR光谱在NR基体中检测到CNFs，如1033和1057处的吸收峰所示 cm−1。热重分析显示，CNF越多，热稳定性越高。拉伸强度和弹性模量也增加。菠萝果渣基CNFs可提高NR复合材料的力学性能和热性能，是一种理想的天然补强材料。
