摘要:

用二步法对气相生长碳纤维(VGCF)进行表面改性处理, 然后用溶液混合法制备了VGCF/形状记忆聚氨酯(SMPU)复合材料. 用扫描电镜观察分析了VGCF在SMPU基体中的分散性以及与基体的界面结合情况, 研究了复合材料的力学性能和热学性能. 结果表明：与未经二步法处理的VGCF相比, 用二步法表面处理使VGCF在基体中的分散性及与基体的界面结合能力得到较大的提高, 且使其对复合材料的拉伸强度及拉伸弹性模量的增强效果更为明显; 虽然SMPU与VGCF复合后的断裂伸长率有所降低, 但是与未处理的VGCF制备的复合材料相比, 断裂伸长率有明显增大; 表面处理的VGCF更有利于提高复合材料的热稳定性.

Abstract：

Surface modification of vapor grown carbon fiber (VGCF) was performed with the two-step method. VGCF/shape memory polyurethane (SMPU) composites were prepared via a solutionmixing method thereafter. The dispersion of VGCF in SMPU and VGCF-matrix interfacial adhesion were observed through scanning electron microscope (SEM). Moreover, the mechanical and thermal properties of the VGCF/SMPU composites were investigated. The results show that the dispersion and interfacial adhesion for the two-step surface modified VGCF are greatly improved than that of the pristine VGCF; The composites prepared with two-step surface modified VGCF have much better tensile strength and modulus reinforcement than that with the pristine VGCF. The elongation at break of the composites are all reduced after compounding of VGCF and SMPU, while the surface modified VGCF reinforced composites show higher elongation at break comparing with the pristine VGCF reinforced composites; The two-step surface modified VGCF is propitious to improve the thermal stability of the composites comparing with the pristine VGCF.
