摘要

本研究采用水热合成法，通过改变FeCl3与CF（0-1）的质量比，将纳米fe2o3颗粒沉积在碳纤维上。通过XRD和XPS分析证实了γ-Fe2O3的存在。当质量比为0.75时，碳纤维表面能提高57.5%，层间剪切强度（ILSS）提高15.3%，电阻率（CFRP）提高153.1%。此外，复合材料的电化学性能得到了显著改善，腐蚀电位变化了- 58.2 mV，腐蚀电流密度降低了2 - 3个数量级。

Improved interfacial and electrochemical properties of CFRP via nano-Fe2O3 coated carbon fibers

This study employed hydrothermal synthesis to deposit nano-Fe₂O₃ particles on carbon fibers (CFs) by varying mass ratio of FeCl₃ to CF (0–1). The presence of γ-Fe₂O₃ was verified through XRD and XPS analyses. When the mass ratio is 0.75, surface energy of CFs increased by 57.5 %, leading to a 15.3 % enhancement in interlaminar shear strength (ILSS) and a 153.1 % rise in electrical resistivity of carbon fiber reinforced polymer (CFRP). Moreover, the composite exhibited significantly improved electrochemical performance, with a −58.2 mV shift in corrosion potential and a reduction in corrosion current density by2–3 orders of magnitude.
