ABSTRACT

The main objective of this investigation is to study the physical, chemical, and morphological analysis of the optimal alkali-treated Perotis indica fiber (PIF). The PIF is treated with 5% (w/v) NaOH in different soaking times (i.e., 15 min, 30 min, 45 min, 60 min, and 75 min). Through thermogravimetric analysis, treatment is optimized at 5% NaOH in a soaking time of 60 min. That optimized alkali – treated PIF is used for further study. Fourier Infrared spectrum (FT-IR) analysis revealed that treatment has leached hemicellulose, lignin, and wax in the fiber. X-Ray Diffraction (XRD) showed improvement in Crystalline size (15.12 nm to 18.51 nm) and Crystalline index (48.3% to 55.43%). Morphological analysis was compared between untreated PIF and treated PIF by atomic force microscopic (AFM) analysis which exposed surface improvements after treatment.

摘要

本次调查的主要目的是研究最佳碱处理籼稻的物理、化学和形态分析。光纤 (PIF)。PIF 在不同的浸泡时间（即 15 分钟、30 分钟、45 分钟、60 分钟和 75 分钟）中用 5% (w/v) NaOH 处理。通过热重分析，在 60 分钟的浸泡时间内优化了 5% NaOH 的处理。该优化的碱处理 PIF 用于进一步研究。傅里叶红外光谱 (FT-IR) 分析表明，处理已浸出纤维中的半纤维素、木质素和蜡。X 射线衍射 (XRD) 显示结晶尺寸（15.12 nm 至 18.51 nm）和结晶指数（48.3% 至 55.43%）有所改善。通过原子力显微镜 (AFM) 分析比较未处理的 PIF 和处理的 PIF 之间的形态分析，该分析显示处理后的表面改进。
