“…The price of the material must be competitive, and this material can easily be made into a membrane [81]. Inorganic membranes [82,83], for example, based on zeolites, may offer a solution to the permeability/selectivity trade-off problem. Their selectivity and permeability data are often in the upper right quadrant of a Robeson plot [78].…”

Based on the results of research works reflected in the scientific literature, the main examples, methods and approaches to the development of polymer inorganic nanocomposite materials for target membranes are considered. The focus is on membranes for critical technologies with improved mechanical, thermal properties that have the necessary capabilities to solve the problems of a selective pervaporation. For the purpose of directional changes in the parameters of membranes, effects on their properties of the type, amount and conditions of nanoparticle incorporation into the polymer matrix were analyzed. An influence of nanoparticles on the structural and morphological characteristics of the nanocomposite film is considered, as well as possibilities of forming transport channels for separated liquids are analyzed. Particular attention is paid to a correlation of nanocomposite structure-transport properties of membranes, whose separation characteristics are usually considered within the framework of the diffusion-sorption mechanism.

“…In recent years, membrane technology has been adopted by many industries, including juice production (An, Hu, Wang, Zhou, & Liu, ), chemical industry (Favvas, Katsaros, Papageorgiou, Sapalidis, & Mitropoulos, ; Takht Ravanchi, Kaghazchi, & Kargari, ), and seawater desalination (Amy et al., ). A few literatures revealed that membrane technology had great potentials for concentrating biogas slurry in terms of valorization.…”

Biogas slurry, also called liquid digestate, refers to the liquid part of the anaerobic digestate produced from the anaerobic digestion process, which is an environmental pollution source if it is discharged without proper treatment. To recover the nutrients in the biogas slurry, a membrane system was designed to concentrate in the work. The effects of pretreatment technology including gravity settling and ultrafiltration process were studied via analyzing the chemical oxygen demand (COD), ammonia nitrogen (NH 3 -N), total nitrogen (TN), and conductivity. Reverse osmosis was applied in the biogas slurry concentration. The performance of reverse osmosis membrane used in the concentration process was studied by analyzing the permeate and concentrate (retentate), the volume reduction factor, and the concentration factor. The suitable parameters were selected as 20.0-25.0°C for influent temperature, 0.8-1.0Mpa for operating pressure, and 6.0-8.0 for influent pH. Furthermore, the feasible concentration factor was evaluated as 4. The economic, environmental, and social benefits could be gained if (concentrated) biogas slurry was used as a substitute for chemical fertilizers. © 2019 Water Environment FederationPractitioner points • Reverse osmosis system was established for biogas slurry concentrating. • The operational factors were optimized on biogas slurry concentrating and separation. • The biogas slurry separation mechanism was discussed.

“…In addition, PIs with good mechanical properties, high thermal stability, and excellent film integrity (defect free) are of great potential for commercial products such as high temperature adhesive tapes, alignment layers for liquid crystal display (LCD) [16][17][18][19][20], etc. PIs also played an important role in the applications of polyelectrolytes (for organic memory devices) [21,22], gate insulators (for organic thin film transistors; OTFTs) [22][23][24][25][26], membranes (for gas separation) [22,27], etc. With the intention of using the recycling C5 byproducts for the synthesis of high-performance PIs, we would like to take advantage of the above-mentioned versatile polymer intermediate, bisphenol CP (Scheme 1) [1].…”

Synthesis and Properties of Cyclopentyl Cardo-Type Polyimides Based on Dicyclopentadiene

A crucial polymer intermediate, 4-[1-(4-hydroxyphenyl)cyclopentyl]-phenol (bisphenol CP), was developed from dicyclopentadiene (DCPD), a key byproduct of the C5 fraction in petrochemicals. On the basis of bisphenol CP, a diamine, 4,4′-((cyclopentane-1,1-diylbis(4,1-phenylene))bis(oxy))-dianiline (cyclopentyl diamine; CPDA) was subsequently obtained through a nucleophilic substitution of bisphenol CP, followed by the hydrogenation process. By using the CPDA diamine, a series of polyimides with cyclopentyl (cardo) units on the backbone were prepared along with a reference polyimide (API-6F) based on 4,4′-(4,4′-(propane-2,2-diyl)bis(4,1-phenylene))bis(oxy)dianiline (BPAA), and 4,4′-(hexafluoroisopropylidene)-diphthalic anhydride (6FDA) for the exploration of structure-properties relationship. Thanks to the presence of cyclopentyl units, this type of cardo polyimides exhibited comparable tensile properties, especially a large elongation (25.4%). It is also worth noting that CPI-6F exhibited better solubility in organic solvents, such as NMP, DMAc, THF, and chloroform, than the other PIs. Gas separation properties were also evaluated for these cardo-type polyimides.
