This study addresses the inherent issues surrounding surface modification methods of nanofibers and proposes an environmentally friendly and less toxic strategy for the surface modification of hydrophilic nanofiber. From the continuation of our previous work, which discussed the easy production of nanofiber (average size: 127 nm) from oil palm mesocarp fiber (OPMF), in this work, the surface of nanofibers (M-IL-OPMF) were modified through vapor-phase-assisted surface polymerization (VASP) to improve the affinity of interface between the polymer grafted M-IL-OPMF and non-polar matrix. VASP of ε-caprolactone was successfully proceeded from the [M-IL-OPMF] at 70 °C for 24 h and 72 h, and compositions were estimated to be 35.7% fiber/64.3% polymer and 27.8% fiber/72.2% polymer. To confirm the grafting of PCL, size-exclusion chromatography (SEC) and Fourier transform infrared (FT-IR) spectroscopy, thermogravimetry (TG), and dispersibility test in hydrophobic solvent were carried out. © 2019 Wiley Periodicals, Inc.

气相辅助表面聚合对纳米木质纤维素纤维的表面改性

本研究解决了围绕纳米纤维表面改性方法的固有问题，并提出了一种环保且毒性较小的亲水性纳米纤维表面改性策略。继续我们之前的工作，讨论了从油棕中果皮纤维（OPMF）轻松生产纳米纤维（平均尺寸：127 nm），在这项工作中，纳米纤维（M-IL-OPMF）的表面通过蒸汽改性相辅助表面聚合（VASP）提高聚合物接枝的M-IL-OPMF与非极性基质之间的界面亲和力。ε-己内酯的 VASP 在 70 °C 下成功地从 [M-IL-OPMF] 进行 24 小时和 72 小时，其组成估计为 35.7% 纤维/64.3% 聚合物和 27.8% 纤维/72.2% 聚合物。为了确认 PCL 的嫁接，进行尺寸排阻色谱（SEC）和傅里叶变换红外（FT-IR）光谱、热重分析（TG）和在疏水溶剂中的分散性测试。© 2019 Wiley Periodicals, Inc.
