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。
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.
