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。 Carbon nanotubes / epoxy acrylate (CNTs / EA) photosensitive resins were prepared by the reaction of functional groups on the surface of carbon nanotubes (CNTs) with epoxy acrylate (EA) oligomers. United prepared a new type of composite coating. The barrier IR / UV performance of the coating was studied. The results showed that the transmittance of the coating was 68.55% in the near infrared (4000 ~ 12000 cm-1) and 85% in the visible (380 ~ 780 nm) UV completely blocked. At the same time, the mechanical property of the composite coating is also improved compared with the EA coating, which has potential application prospect in the photoresist barrier coating.
