摘要

纤维素是一种令人着迷的生物聚合物和可持续原料。至少具有一个纳米尺度的纤维素颗粒被称为纳米纤维素。红麻纤维是一种用于本研究的天然纤维,因为它具有高的机械性能和与聚合物的强界面附着力,因此它提供了优于其他天然纤维的性能。聚氨酯(PU)泡沫被广泛用作夹层复合材料结构的芯层,以生产轻质材料。本文研究了从印度尼西亚东爪哇红麻纤维中提取的纤维素纳米原纤维(CNF)的合成,分析了在PU泡沫复合材料中添加CNF作为填充剂和增强剂的效果,并提出了一种PU-CNF泡沫复合材料的配方,该复合材料在结构应用中具有最佳的力学性能,是一种坚固而轻质的材料。从红麻纤维中提取CNF,首先对纤维进行碱化和漂白预处理,然后用超细磨机进行机械处理,得到CNF悬浮液。CNF在PU泡沫中的重量变化分别为0、3、5、7、10 wt%。原位聚合法制备PU-CNF复合材料。CNF的表征包括TEM, XRD和FT-IR。透射电镜结果表明,CNF的直径在40 ~ 70 nm之间。红外光谱结果表明,预处理工艺成功地降低了红麻纤维的木质素和半纤维素含量。XRD结果表明,CNF结晶度为75.22%。PU-CNF泡沫复合材料的表征包括压缩测试、三点弯曲测试和扫描电镜。从压缩试验和三点弯曲试验的结果来看,3 wt% CNF增强的PU泡沫复合材料具有最优值,是最佳复合材料。抗压强度值从236.997 kPa增加到284.434 kPa,增加了20.01%;抗压模量从5.67 MPa增加到7.32 MPa,增加了29.21%;三点弯曲强度从572.24 kPa增加到734.15 kPa,增加了28.29%。所有的结果都支持CNF是一种具有高表面积的潜在增强材料,适用于各种应用。

Synthesis and Effect of Nanocellulose Obtained from East Java Kenaf Fiber on Mechanical Properties of Polyurethane Foam Composites as Strong and Lightweight Materials
Cellulose is a fascinating biopolymer and sustainable raw material. Cellulose particles with at least one dimension in the nanoscale are referred to as nanocellulose. Kenaf fiber is a natural fiber used in this study because it has high mechanical properties and strong interface adhesion with polymers so it provides superior properties to other natural fibers. Polyurethane (PU) foam is widely used as a core layer in sandwich composite construction to produce a lightweight material. This study presents a synthesis of cellulose nano-fibrils (CNF) extracted from East Java, Indonesia based kenaf fibers, an analysis of the effect of adding CNF as a filler and a reinforcement in PU foam composites, and a formulation of PU-CNF foam composite that provided the best mechanical properties as strong and lightweight materials in structural applications. The CNF extraction from kenaf fiber started by fiber pre-treatment including alkalization and bleaching, then mechanical treatment with an Ultra Fine Grinder to produce CNF suspension. The weight variations of CNF in PU foam were 0, 3, 5, 7, and 10 wt%. PU-CNF composite fabrication using the in-situ polymerization method. CNF characterization included TEM, XRD, and FT-IR. TEM results on CNF show that the CNF diameter is in the range of 40-70 nm. The functional group from the FT-IR results showed that the pre-treatment process on kenaf fiber was successful in reducing the lignin and hemicellulose content. XRD results showed that the CNF crystallinity was 75.22%. The PU-CNF foam composite characterization included a compressive test, 3-point bending test, and SEM. The PU foam composite with 3 wt% CNF reinforcement is the best composite which has the optimum value from the results of the compression test and the 3-point bending test. The compressive strength value increased by 20.01%, from 236.997 kPa to 284.434 kPa, the compressive modulus value increased by 29.21% from 5.67 MPa to 7.32 MPa, and the 3-point bending strength value increased 28.29% from 572.24 to 734.15 kPa. All the results expected to support that CNF was a potential reinforcement material with a high surface area for a wide variety of applications.
