| 摘要: | 包裝在許多領域扮演著重要的角色，例如食品、藥品、電子產品等。 此 外，氧氣阻隔性能有時是包裝材料最關鍵的討論因素。隨著技術的進步和行業 的進步，我們需要開發智能包裝以應用於不同的領域。
混合基質薄膜 (MMMs) 常用於分離混合氣體。 此外，混合基質薄膜通常是 通過澆鑄方法合成的，即將前體溶液倒在板上，然後通過蒸發去除溶劑。 這項 研究的重點是另一種通過紫外線固化製造膜的方法，與熱固化聚合物塗層相 比，它具有明顯的優勢。 除了固化時間快之外，紫外線固化還涉及較低的資本 投資和運營成本，並且是一種無溶劑工藝。
為了開發一種易於加工的合適的多功能包裝材料，我們在氧化石墨烯上原 位生長了正八面體 的 UiO-66-NH2， 以此作為填料。並使用快速的 UV 固化聚 合物聚乙二醇二丙烯酸酯和無溶劑工藝來製造混合基質薄膜。 並利用 X 射線衍 射儀 (XRD)、傅里葉轉換紅外光譜 (FTIR)、超高解析冷場發射掃描式電子顯微 鏡 (SEM)、動態光散射 (DLS)、熱重分析 (TGA)、Brunauer-Emmett-Teller (BET)、拉曼光譜、機械性能、單一氣體滲透實驗用於表徵填料和膜。
;Packaging plays an important role in our daily life in many fields, such as food, medicine, and electronic products. Besides, oxygen barrier performance is sometimes the most critical discussion factor for packaging materials. With advances in technology and industry progress, we need to develop intelligent packaging to apply to different fields.
Mixed matrix membranes (MMMs) are popular for separating mixed gases. Moreover, MMMs are synthesized using a casting method, wherein the precursor solution is poured onto a plate, and then the solvent is removed through evaporation. This research focuses on another way to fabricate membranes via UV curing, which provides distinct advantages compared to thermally cured polymer coatings. In addition to the fast curing time, UV curing also involves lower capital investment and operating costs and is a solvent-free process.
To develop a suitable and multifunctional packaging material that is easily processable, we synthesized in-situ growth of octahedral amine-functionalized UiO- 66 on the surface of graphene oxide nanosheets as a filler and used UV curable polymer PEGDA and a solvent-free process to fabricate MMMs. X-Ray diffraction (XRD), Fourier-transform infrared (FTIR), scanning electron microscopy (SEM), dynamic light scattering (DLS), thermogravimetric analysis (TGA), Brunauer- Emmett-Teller (BET), Raman spectroscopy, mechanical properties and single gas permeability were used to characterize fillers and membranes. |
