摘要

考察了碱、硅烷和复合处理对苎麻纱线纤维力学性能和热性能的影响。用5%的氢氧化钠（NaOH）和3-（氨基丙基）三甲氧基硅烷（APTES）分别以1%和3%的浓度处理纤维。复合处理增强了纤维的疏水性，接触角达到80.02°，XRD分析证实结晶度提高到96.26%，界面抗剪强度提高到5.05 MPa，使纤维更坚硬，更耐用。FTIR分析显示，这种处理在破坏木质素和半纤维素键方面的有效性，证明了苎麻在材料复合长丝3D打印中的可持续增强潜力。

Characterization of alkali and silane treated ramie yarn fibers as sustainable reinforcement for polymer composite

The effect of alkali, silane, and combined treatments has been evaluated to enhance the mechanical and thermal properties of ramie yarn fiber. The fibers were treated with 5 % sodium hydroxide (NaOH) and 3-(Aminopropyl) trimethoxy silane (APTES) at 1 % and 3 % concentrations. Combined treatments enhanced fiber hydrophobicity, achieving a contact angle of 80.02°, and XRD analysis confirmed crystallinity increased to 96,26 % and interfacial shear strength improved to 5.05 MPa, contributing to stiffer and more durable. FTIR analysis revealed the effectiveness of this treatment in breaking lignin and hemicellulose bonds, demonstrating ramie potential for sustainable reinforcement in material composite filament 3D printing.
