Incorporation of nanoparticles in membranes has recently been reported to lead to enhancement of the membrane performance for various applications. In this study, ZnO nanoparticles were synthesized via sol-gel method using zinc acetate and oxalic acid as starting materials. However, the influence of additive, in this case ethylene glycol (EG), on the size of ZnO nanoparticles produced was investigated. All diffraction peaks of XRD patterns indicated the wurtzite structure and the hexagonal phase of ZnO nanoparticles. Uniform spherical particle sizes with lower sizes and reduced agglomeration were observed when EG was used under the same experimental conditions. The particle size was found in the range of 20-30 nm when EG was used as compared to those without EG, which was between 50-60 nm. Dispersion property of the ZnO NPs was further verified by zetasizer analysis. Subsequent incorporation of the smaller size ZnO nanoparticles in membranes has shown improvement in the characteristics and performance of the membranes. Membranes incorporated with ZnO showed improved hydrophilicity and enhancement of membrane performance in terms of permeability, porosity, and rejection ability.

“…15 Ion exchange capacity (IEC) and the degree of sulfonation (DS) of the prepared SPEEK were determined by H + release amount. For this, minced SPEEK ($1 g) was suspended in 2 M NaCl solution (100 mL) for 24 h. The resulting solution was titrated using 0.1 M NaOH solution with phenolphthalein as indicator.…”

A promising avenue to preserve harvested fruits and vegetables can be achieved by designing a "breathable" membrane named as equilibrium modified atmosphere packaging (EMAP). In this work, such "breathable" packaging was prepared using a gas conductor -gas barrier (GC-GB) blending membrane (BM). The miscibility between the GC and GB in the BM was displayed using structural scanning and thermal analysis, and the physicochemical properties of the BM were characterized by a series of assays. By changing the SPEEK content in the BM, CO 2 permeabilities of the BM in pure gas can be adjusted from 105 to 1494 kPa, while the O 2 permeabilities can be adjusted from 19 to 297 kPa. Thus, the CO 2 /N 2 and O 2 /N 2 ideal selectivity of the BMs were 20.48-33.95 and 5.38-6.75, respectively. On this basis, the membrane was used to preserve oranges and cauliflower. The equilibrium internal atmospheres included 4.6-7.9% of CO 2 + 7.8-4.4% of O 2 (p/p) and 3.6-8.7% of CO 2 + 9.2-4.2% of O 2 (p/p), which were respectively recommended to preserve the stored products. The results indicated such adjustable membranes will have promising applications to preserve different kinds of fresh products.
