摘要

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。

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.
