“…The ILs examined here exhibit glass transition temperatures between À120 and À75 C with 0.2 nm 3 < V m < 0.5 nm 3 and have lower T g than the alkali inorganic salts [55] with lower V m . Moreover, imidazolium and other organic IL cations can be synthesized with either vinyl, acryl or methacryl groups so that the IL monomers (substituted with polymerizable functional groups) can be easily polymerized to create PILs, which carry an ionic liquid species in each of the repeating units [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36].

“…These materials have shown tunable mechanical behavior and high ionic conductivities [66][67][68][69], which enable applications in electrochemical devices [70][71][72]. Inspired by the enhanced CO 2 separation performances of PIL composite materials reported by Bara et al [58], we further developed an ABA-triblock copolymer ion gel with a PIL midblock for CO 2 separation applications [73]. Gas permeation studies showed that this ion gel has both high permeability and favorable selectivity for CO 2 /N 2 and CO 2 /CH 4 gas pairs which exceeded the famous ''upper bound'' on the respective Robeson plot [74,75].…”

“…Furthermore, BCPs allow for a precise control on the internal morphology of the membranes, so that different levels of tortuosity and connectivity in between domains can be achieved. 144,145 Similar strategies have been already implemented in membranes for fuel-cell applications. 146 This type of membranes can incorporate a broad range of ion-conducting groups such as the ones described in the In terms of the gas barrier blocks, polymers with high level of crystallinity, high glass transition temperatures, and/or low free volume could be incorporated to reduce gas crossover.…”

The conception of practical solar-hydrogen generators requires the implementation of engineering design principles that allow photo-electrochemical material systems to operate efficiently, continuously and stably over their lifetime. At the heart of these engineering aspects lie the mass transport of reactants, intermediates and products throughout the device. This review comprehensively covers these aspects and ties together all of the processes required for the efficient production of pure streams of solar-hydrogen. In order to do so, the article describes the fundamental physical processes that occur at different locations of a generalized device topology and presents the state-of-the-art advances in materials and engineering approaches to mitigate masstransport challenges. Processes that take place in the light absorber and electrocatalyst components are only briefly described, while the main focus is given to mass transport processes in the boundary-layer and bulk liquid or solid electrolytes. Lastly, a perspective on how engineering approaches can enable more efficient solar-fuel generators is presented. Broader contextSolar-hydrogen generators have the potential to trigger the incorporation of a much larger share of solar energy sources in our current energy landscape. These technologies can directly capture and store energy from the sun in the form of hydrogen molecules. As hydrogen can be transported, and stored for long periods of time, solar-hydrogen devices allow for the spacio-temporal decoupling of the energy generation and consumption processes, and in this way provide a larger flexibility to the electrical grid. While significant focus has been given to the development of photoelectrochemical materials for solar water-splitting, equally important are engineering aspects related to the materials' integration into devices that can operate stably, and produce pure hydrogen streams continuously over long lifetimes. This review provides a broad view on these engineering challenges and approaches to conceive practical solar-hydrogen generators.
