“…This is because MIL-68 has a high-porosity hexagonal window with an extremely high multi-layer adsorption capacity. The framework is also capable of providing strong hydrogen bonds for acetic acid with a corresponding adsorption energy reaching −119.32 kJ mol −1 , 11 thus the high adsorption capacity is recorded. A summary of the pore sizes of the MOFs as well as the kinetic diameters of the VOCs are presented in Table S1 (ESI†) to provide a better comparison.…”

“…Synthesis of MIL-68. Synthesis was carried out in accordance with our previous work 11 with minor modifications as follows: 120.7 g (500 mmol) of AlCl 3 Á6H 2 O was dissolved in 2 L of IPA, and 41.7 g (250 mmol) of H 2 BDC was added afterwards. It was stirred for 5 days in a 100 1C oil bath and the obtained product was washed 3 times with 1 L of MeOH and dried in an oven at 75 1C for 1 day to obtain 36.6 g (yield: 70.3%) of the white powdered product.…”

“…9 In the published literature, two examples of scalable MOFs, or MOFs that may be synthesized on a larger scale with no apparent changes in their properties include HKUST-1 10 and MIL-68(Al). 11 These two MOFs may be synthesized on a large scale without encountering many problems. Other promising MOFs that may be evaluated for their capability to undergo large scale production include ZIF-8 12 and A520.…”

“…The coating agent components are listed in components were selected as the standard of economics or safeness with reliable references. Isopropyl alcohol (IPA) is used as a chemical intermediate and in solvent applications in medicine and industry (Logsdon et al, 2000) and has the advantage of being low-cost (So et al, 2021). Regarding selecting an optimal coating agent for application to greenhouses some agents incorporate IPA as a solvent; however IPA is a volatile organic compound classified as a harmful atmospheric substance.…”

Comparative study of coating agents for prevention of fine-dust-induced light transmittance reduction in greenhouse covering materials

et al. 2022

Recently, rapidly growing industry and abnormal climate change have generated high concentrations of fine dust. This fine dust settles on greenhouses and hinders photosynthesis of the plants within. In this study, the greenhouse environment was reproduced using fine dust devices, and the fine dust adhesion and washing efficiency were compared. The optimal coating agent was selected by performing a coating experiment to assess the changes in the light transmittance and contact angles of eight greenhouse coatings incorporating different coating agents. The most pronounced adhesion rate was observed in an ion humidification test for (NH4)2SO4. The coating agent with Teflon, which exhibited the largest contact angle in this study, had the highest washing efficiency, followed by the coating agent with the highest polydimethylsiloxane ratio using isopropyl alcohol (IPA) as a solvent, and the coating agent with the highest polydimethylsiloxane using water as a solvent. However, the ingredients added to the agents with Teflon or IPA were judged inappropriate for greenhouse use due to environmental reasons. Therefore, the coating agent with the highest polydimethylsiloxane using water as a solvent, which is the most suitable coating agent and satisfies both the washing efficiency and contact angle requirements, is expected to be used as a greenhouse coating agent to prevent light transmittance reduction in greenhouses due to fine dust accumulation.

“…Various water stable MOFs with varying pore windows including UiO-66, UiO-66-NH 2 , MIL-68(Al), MIL-100(Fe) and A520 were used for the preparation of the MMMs. These MOFs were also considered for use due to their easy and sustainable large-scale synthesis suitable for industrial application [34][35][36][37][38].…”

Zeolitic imidazole framework (ZIF-8) was incorporated into poly(ether-block-amide) (Pebax-1657) in differing ratios to prepare mixed matrix membranes (MMMs) for gas separation. As ZIF-8 loading is increased, gas separation selectivity also gradually increases. For economic considerations, the proportion of the increase in selectivity to the amount of MOF loaded per unit was calculated. The results show that mixing 5% MOF gives the best unit performance. With this, a variety of MOFs (UiO-66, UiO-66-NH2, A520, MIL-68(Al) and MIL-100(Fe)) were mixed with PEBAX at 5 loading to prepare MMMs. In this work, metal-organic frameworks (MOFs) were processed using the dry-free method, where in the synthesized MOF was not dried prior to incorporation. The gas separation performance test carried out shows the highest separation performance was exhibited by P-UiO-66, wherein the CO2/N2 gas selectivity was 85.94, and the permeability was 189.77 (Barrer), which was higher than Robeson’s Upper bound in 2008, and obtained a high permeability and selectivity among mixed matrix membranes. In the preparation of high quality MMMs for gas separation, details regarding the interface phenomenon were assessed.
