| dc.description.abstract | 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. | en_US |
