“…Solution casting methods are used not only for the preparation of monolayer microporous separators but multilayer separators are also synthesized through the multisolution coating on the substrate. The morphology and pore size of separator prepared through the solution casting method depend upon the solubility of polymers, type of phase separation used (nonsolvents, thermal, or evaporative), the evaporation rate of solvents, and miscibility of solvents and nonsolvents in case of nonsolvent phase separation . The morphology of separator prepared through the solution casting method is shown in Figure d.…”

metric tons of carbon dioxide (CO 2 ) and other pollutants per year, which accelerate global warming and major climate changes. [2] In order to mitigate these serious issues caused by fossil fuels and to compete with the energy generating devices based on fossil fuels, renewable energy sources like solar energy, wind energy, bioenergy, and geothermal energy are potential alternative power resources. However, these renewable energy resources need highly efficient energy storage devices for integrating and well distribution of energy. Rechargeable battery technology with high energy, high power density, long life cycle capability, fast cycling rate, and reasonable cost is the possible solution to store energy obtained from these renewable sources. [3] Among many rechargeable energy storage devices, lithium-ion batteries (LIBs) are the promising energy sources for integrating renewable resources and high power applications, owing to high energy density, lightweight, high flexibility, slow self-discharge rate, high rate charging capability, long battery life, and environmental benignity. [4,5] The aforementioned attractive properties of rechargeable LIBs promote its utilization in the wide range of applications like laptops, cell phones, electric vehicle, hybrid electric vehicles, renewable power stations, stationary electric power, defense arsenal, subsurface exploration, thermal reactors, and space vehicles. [6][7][8][9] From the last 30 years, rapid development has been observed in LIBs technology. Presently, LIBs hold twofold energy density as compared to the first commercial LIBs developed by Sony in 1991, but still, there are some challenges associated with LIBs that need to be solved for achieving high power density and efficient performances at high and low temperatures. Safety, cost, and enhancement in energy and power densities are the major concerns in next generation LIBs. [10][11][12] Separator is one of the important components of LIBs that is not directly involved in the electrochemical reaction, however, its properties, structure, and composition greatly influence the performance of batteries with respect to internal resistance, long cycle performances, high capacity, and safety. [13] The basic functions of the separator are to prevent the contact between anode and cathode to avoid internal short circuits, store liquid electrolyte, and permit the migration of ions during the chargedischarge process. [14][15][16] The ideal separator should possess Lithium-ion batteries (LIBs) are promising energy storage devices for integrating renewable resources and high power applications, owing to their high energy density, light weight, high flexibility, slow self-discharge rate, high rate charging capability, and long battery life. LIBs work efficiently at ambient temperatures, however, at high-temperatures, they cause serious issues due to the thermal fluctuation inside batteries during operation. The separator is a key component of batteries and is crucial for the sustainability of LIBs at high-temperatures. Th...

“…The use of PV processes for industrial applications has increased steadily over recent decades, with initial applications being explored as early as 1958 by Binning et al [12,13] and patents being published in the 1960s by Binning et al [14] and Loeb et al [15], then being further developed in the years afterwards [6,16,17]. During that time it was noted that the fluxes obtained from the membranes then available were too low to be economically viable for industrial use [18].…”

The potential of polymers of intrinsic microporosity (PIMs) and PIM/graphene composites for pervaporation membranes

Pervaporation (PV), a membrane process in which the feed is a liquid mixture and the permeate is removed as a vapour, offers an energy-efficient alternative to conventional separation processes such as distillation, and can be applied to mixtures that are difficult to separate, such as azeotropes. Here the principles of pervaporation and its industrial applications are outlined. Two classes of material that show promise for use in PV membranes are described: Polymers of intrinsic microporosity (PIMs) and 2D materials such as graphene. The literature regarding PV utilizing the prototypical PIM (PIM-1) and it hydrophilic hydrolysed form (cPIM-1) is reviewed. Self-standing PIM-1 membranes give competitive results compared to other membranes reported in the literature for the separation of alcohols and other volatile organic compounds from aqueous solution, and for organic/organic separations such as methanol/ethylene glycol and dimethyl carbonate/methanol mixtures. Blends of cPIM-1 with conventional polymers improve the flux for dehydration of alcohols. The incorporation of fillers, such as functionalised graphene-like fillers, into PIM-1 to form mixed matrix membranes can enhance the separation performance. Thin film composite (TFC) membranes enable very high fluxes to be achieved when a suitable support with high surface porosity is utilised. When functionalised graphene-like fillers are introduced into the selective layer of a TFC membrane, the lateral size of the flakes needs to be carefully controlled. There is a wide range of PIMs and 2D materials yet to be explored for PV applications, which offer potential to create bespoke membranes for a wide variety of organic/aqueous and organic/organic separations.

“…Great prospects in this field of membrane science are associated with the appearance of special techniques for the inclusion of nanoparticles in the material [43,52,151], with the expansion of the spectrum of nano-fillers from which a useful effect is expected [45,52,148,152,153], as well as with the appearance of methods for analyzing and visualizing the distribution and the state of fillers in matrices of different morphologies [29,51,135,154]. New polymeric materials are engaged in the synthesis of nanocomposite membranes, including those responsive to stimuli, and are also capable of self-organization or forming compositionally heterogeneous films [92,97,102,[155][156][157]. Their use makes it possible to influence the nature of the distribution of nano-fillers in the matrix.…”

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.
