This work evaluated the effects of cold plasma treatment on kapok fibers (Ceiba pentandra L.). Fourier-transform infrared (FTIR) spectra showed changes in characteristic absorption bands, indicating modification of the chemical composition of the fiber. Surface roughness, observed by field-emission gun scanning electron microscope (FEG-SEM), increased. Furthermore, the water uptake was significantly affected, the ability to uptake oil increased and a mechanism of reaction was suggested. The thermal behavior, analyzed by thermogravimetric analysis (TGA), was slightly altered and it was also shown that fiber surface was activated by the plasma treatment. Ultimately, cold plasma may prove as a feasible approach to improve fiber-matrix adhesion for the production of biodegradable polymer composites.

这项工作评估了冷等离子体处理对木棉纤维（Ceiba pentandra L.）的影响。傅立叶变换红外（FTIR）光谱显示了特征吸收带的变化，表明纤维化学成分的改变。通过场发射枪扫描电子显微镜（FEG-SEM）观察到的表面粗糙度增加了。此外，显着影响了水的吸收，增加了吸收油的能力，并提出了反应机理。通过热重分析（TGA）分析的热行为略有改变，并且还显示出通过等离子体处理可以活化纤维表面。最终，冷等离子体可能被证明是提高纤维基质粘附性以生产可生物降解的聚合物复合材料的可行方法。
