Effect of Various Chemical Treatments of Prosopis juliflora Fibers as Composite Reinforcement: Physicochemical, Thermal, Mechanical, and Morphological Properties

ABSTRACT

The present environmental regulations enforced by the government authorities have made the investigators around the globe to make use of more and more green materials particularly in composite systems. In this context, natural fibers play an important role and proven to be excellent reinforcements in polymer matrices. However, these natural fibers have got one major limitation: their incompatible hydrophilic behavior which affects their bonding with hydrophobic matrixes. Researchers over the years have come up with several fiber surface modification processes to overcome this defect. So, in this present study, the effect of various chemical treatments like alkaline, benzoyl peroxide, potassium permanganate, and stearic acid on Prosopis juliflora fibers has been discussed. These various chemical treatments on the fiber surfaces impacted on their structure, composition, and properties which were discovered through chemical analysis, Fourier transform-infrared, X-ray diffraction, thermogravimetric analysis, differential scanning calorimetry, scanning electron microscopy, and tensile testing.

摘要

政府当局实施的现行环境法规已经使世界各地的调查人员越来越多地使用绿色材料，特别是在复合系统中。在这种情况下，天然纤维起着重要的作用，并证明是优异的增强聚合物基质。然而，这些天然纤维有一个主要的局限性：它们不相容的亲水性影响了它们与疏水性基质的结合。多年来，研究人员已经提出了几种纤维表面改性方法来克服这一缺陷。因此，本研究探讨了碱、过氧化苯甲酰、高锰酸钾和硬脂酸等化学处理对Paopopijululula纤维（PJFS）纤维的影响。通过化学分析、FTIR、XRD、TGA、DSC、SEM和拉伸试验发现，纤维表面的各种化学处理对纤维的结构、组成和性能均有影响。
