【摘要】 利用碳纳米管(CNTs)表面官能团与环氧丙烯酸酯(EA)齐聚物的反应,制备了碳纳米管/环氧丙烯酸酯(CNTs/EA)光敏性树脂,通过紫外光(UV)固化交联制备出新型复合涂层。研究了涂层的阻隔红外/紫外线性能,在近红外区(4000~12000 cm-1)的阻隔率为68.55%,对可见光(380~780 nm)的透过率大于85%,对于<300 nm的紫外线完全阻隔。同时复合涂层力学性能与EA涂层相比也得到提高,在光阻隔涂层方面具有潜在的应用前景。更多还原

【Abstract】 UV curing coating of carbon nanotubes/epoxy acrylate(CNTs/EA) was prepared by the molecule group reaction of CNTs with EA.The anti-infrared/ultraviolet property was characterized by UV-vis and FTIR.The results demonstrate that,its transmittance is greater than 85% in visible spectrum,the ratio of wave shielding is 68.55% in near infrared wave range(4000~12000 cm-1) and it shields all of wave in ultraviolet the region(<300 nm).At same time the mechanical property of composite coating is improved.So these new nano-composite materials would be expected to be a wave shielding thin coating in functional applications.更多还原
