碳纳米材料如氧化石墨烯、碳纳米管等作为高性能填料近年来得到诸多关注与研究.通过物理共混法制备了氮掺杂石墨烯/水性聚氨酯(N-GO/WPU)和氨基化碳纳米管/水性聚氨酯(CNT-NH2/WPU)两种复合材料.研究结果表明,当碳纳米材料用量为 2%时,复合材料的物理力学性能最好,N-GO/WPU和CNT-NH2/WPU的拉伸强度、断裂伸长率、杨氏模量分别为41.3 MPa、745.2%、10.3 MPa和 43.2 MPa、825.1%、12.4 MPa.5%碳纳米材料用量下,复合材料电磁屏蔽性能和疏水性能最佳,N-GO/WPU和CNT-NH2/WPU的电阻、水接触角分别为 2.10×109 Ω、78.3°和8.70×1010 Ω、76.6°.从粒子性能上看,复合材料的综合性能与碳纳米材料在聚氨酯基质中的分散能力有关.
Effect of Cationic Carbon Nanomaterials on the Properties of Waterborne Polyurethane
Carbon nanomaterials such as graphene oxide and carbon nanotubes have received a lot of attention and research as high-performance fillers in recent years.Two composite materials,N-doped graphene/water-based polyurethane(N-GO/WPU)and aminated carbon nanotubes/water-based polyurethane(CNT-NH2/WPU),were prepared by physical blending method.Research results showed that when the amount of carbon nanomaterials was 2%,the composite material had the best physical mechanical properties.The tensile strength,elongation at break,and Young's modulus of N-GO/WPU and CNT-NH2/WPU were respectively 41.3 MPa,745.2%,10.3 MPa and 43.2 MPa,825.1%,12.4 MPa.At the dosage of 5%carbon nanomaterials,the electromagnetic shielding performance and hydrophobic performance of the composite material were the best.Respectively,the resistance and water contact angle of N-GO/WPU and CNT-NH2/WPU were 2.10×109 Ω,78.3°and 8.70×1010 Ω,76.6°.From the perspective of particle properties,the overall performance of composite materials was related to the dispersion ability of carbon nanomaterials in the polyurethane matrix.
