摘要:

在碳纤维表面自聚合沉积多巴胺对其改性，制备出碳纤维增强尼龙6复合材料(CF/PA6)。使用扫描电镜(SEM)、原子力显微镜(AFM)、接触角测量仪、傅里叶红外光谱(FTIR)以及X射线光电子能谱仪(XPS)等手段表征碳纤维的表面形貌、粗糙度、润湿性和化学结构，研究聚多巴胺(PDA)沉积时间对复合材料界面力学性能的影响。结果表明：经过改性处理的碳纤维表面被一层均匀的PDA薄膜覆盖，显著提高碳纤维的表面活性、表面粗糙度和化学键能，也极大地提高碳纤维与尼龙6树脂基体之间的界面相容性。PDA沉积16 h的复合材料其界面结合强度最高，层间剪切强度达到31.7 MPa比改性前提高72.3%，弯曲强度达到308.2 MPa比改性前提高56.9%。

Abstract：

Carbon fiber was surface modified with dopamine via self-polymerizing deposition process, then the polyamide 6-based composites (CF/PA6) were prepared with the modified carbon fiber as reinforcement. The morphology, roughness, wettability and chemical construction of carbon fiber were characterized by scanning electron microscope (SEM), atomic force microscope (AFM), contact angle measuring device, Fourier transform infrared spectrometer (FTIR) and X-ray photoelectron spectroscopy (XPS). The effect of deposition time of polydopamine (PDA) on the interface mechanical properties of the composites was also investigated. The results show that the surface of the modified carbon fiber was covered by a uniform PDA film, which significantly increased the surface activity, surface roughness and chemical bond energy of the carbon fiber, and greatly improved the interfacial compatibility between the carbon fiber and polyamide 6 matrix. The optimal PDA deposition time for the modification of carbon fiber was 16h, correspondingly, with the optimally modified carbon fiber as reinforcement, the interlaminar shear strength and bending strength of composites reached 31.7 MPa and 308.2 MPa, which was 72.3% and 56.9% higher respectively than those of the ones reinforced with the blank carbon fiber.
