In this study, the surface of the raw Musa acuminata peduncles fiber (MAPF) was modified by using a 5 (w/v) % alkali solution. MAPF was immersed in an alkali solution for different soaking durations such as 15, 30, 45, 60, and 75 min. After the alkalization, chemical analyses were conducted for raw and alkalized fibers. The outcome of the chemical analysis revealed that 60 min of soaking time is optimal since it has a higher cellulose fraction (74.22 wt.%) than raw (66.43 wt.%) and alkalized fibers with other soaking durations. Reduced diameter (51.46 µm from 64.74 μm) and slightly increased density (992 kg/m³ from 942 kg/m³) of the optimally alkalized MAPF were established through physical analyses. The Fourier transform infrared spectroscopy and nuclear magnetic resonance spectroscopy witnessed the eradication of amorphous fraction from the optimally alkalized MAPF. The suitability of raw and optimally alkalized MAPF as reinforcement in polymer composites used in high-temperature working environments were analyzed through thermogravimetric analysis, which proved that MAPF-reinforced plastics could be used up to 175 °C. Improvements in the bonding ability of the optimally alkalized MAPF with polymer matrix were authorized by scanning electron microscope and atomic force microscope analysis. Enhancement in the single fiber tensile strength (96.5 ± 32.7 to 162 ± 53.7 MPa) and tensile modulus (2.22 ± 0.976 to 3.46 ± 0.846 GPa) of the optimally alkalized MAPF were corroborated by single fiber tensile testing.

在这项研究中，使用 5 (w/v) % 碱溶液对原始芭蕉梗纤维 (MAPF)的表面进行了改性。将 MAPF 浸入碱溶液中，浸泡时间不同，例如 15、30、45、60 和 75 分钟。碱化后，对原纤维和碱化纤维进行化学分析。化学分析的结果表明，60 分钟的浸泡时间是最佳的，因为它的纤维素含量 (74.22 wt.%) 高于原始纤维 (66.43 wt.%) 和其他浸泡时间的碱化纤维。直径减小（从 64.74 μm 变为 51.46 μm）并且密度略有增加（从 942 kg/m ³变为 992 kg/m ³) 的最佳碱化 MAPF 是通过物理分析建立的。傅里叶变换红外光谱和核磁共振光谱见证了最佳碱化 MAPF 中无定形部分的消除。通过热重分析，分析了原始和优化碱化的 MAPF 作为增强材料在高温工作环境中使用的聚合物复合材料的适用性，证明 MAPF 增强塑料可以在高达 175 °C 的温度下使用。优化碱化的 MAPF 与聚合物基体的结合能力的提高通过扫描电子显微镜和原子力显微镜分析得到证实。单纤维拉伸强度（96.5 ± 32.7 至 162 ± 53.7 MPa）和拉伸模量（2.22 ± 0.976 至 3.46 ± 0）的增强。
