“…Pattern formation, one of the characteristic features of complex systems that results from orderly self-organization of its moieties, has been a key mechanism for providing unique functionalities to synthetic soft materials. [1][2][3][4][5][6][7][8][9][10][11][12][13] Harnessing reactiondiffusion (RD) phenomena through external stimuli, has been a prevalent method for creating spatiotemporal ordered clusters of soft matter, including polymer blends, composites, and gels. [8][9][10][11][12][14][15][16] Here, we develop a noninvasive technique that uses electric field to create self-assembled ordered phase morphologies in polymer ionic liquid (PIL) blends via RD.…”

“…[18] Some of the contactless patterning techniques, such as laser scanning, photolithography, and electron beam lithography, provide more flexibility in terms of pattern replication by directly etching the desired topology onto the substrate using electromagnetic radiation. [1,5,6,19] Here, however, the ordering of domains on the substrate is dependent upon the wavelength of the irradiating beam. [6] In contrast to lithography, recent contactless techniques harness various mechanisms for pattern generation including self-organization, phase separation, surface instabilities, and RD.…”

“…Typically, ILs have been known to possess remarkable properties such as high ionic conductivity, nonvolatility, high chemical, and thermal stability, and have been used as reaction solvents, media for extraction processes, multifunctional agents, and electrolytes in energy conversion and storage devices. [4][5][6][7]23,[29][30][31][32][33][34][35][36][37][38][39][40][41][42] In addition, it has been demonstrated through simulations that ILs, under the influence of electric field, can change from disordered to ordered states. [30] Incorporation of polymer in ILs, which provides good mechanical strength to the system as an added advantage, [34,43,44] is achieved in two ways.…”

“…First is the synthesis route, wherein one of the IL ions (mostly cations) is a repeating unit connected through a polymeric backbone; these are known as poly(ionic liquid) or polymeric ionic liquids (pILs). [5,7,23,35,[37][38][39][40] Second is the mixing route, in which a polymer and an IL, which exist as separate entities, are combined together to form PIL blends. [6,29,31,44] Although pILs have traditionally been used in many applications, [5,33,35,[37][38][39]44] there usage is sometimes discouraged as these materials are usually not able to fully retain the unique features of ILs.…”

Directing reaction-diffusion (RD) phenomena, through the use of external stimuli has been one of the widely used approaches for designing multifunctional soft materials. Using modeling and simulation, it is demonstrated that the nonuniform electric field can be harnessed to create intricate ordered patterns in polymer ionic liquid (PIL) blends. The investigation begins with the establishment of the equilibrium phase diagrams of electroresponsive PIL blends and subsequently, use the Poisson-Nernst-Planck equations to model the kinetics of pattern formation. The simulations reveal that in the presence of nonuniform electric field the ionic liquid (IL) rich domains self-aggregate in high electric field regions. Thus, the ordering of the electric field regions effectively dictates the ordering of the IL-rich phase in the PIL blends. It is also demonstrated that the mechanism of spatiotemporal pattern formation is quite robust and can be dynamically controlled by varying the distribution of electric field. It is believed that the methodology provides a simplistic mechanism for creating ordered patterns in soft materials through RD phenomena that can be exploited for designing other similar stimuli-responsive systems.

Abstractβ-Irradiation (“e-beaming”) as well as swelling in ionic liquids, each process by itself, are common pretreatments in biorefinery scenarios. A combination of both, such as occurs with β-irradiation of biomass that was insufficiently washed and still contains traces of ionic liquids, causes covalent derivatization of the contained cellulose and incorporation of nitrogen. The nitrogen uptake occurred only in the presence of the ionic liquid and correlated linearly with both the irradiation dose and the concentration of the contained ionic liquid. The presence of other wood constituents during β-irradiation decreased nitrogen uptake, but did not prevent it. The derivatization of cellulose did not depend on the degree of crystallinity, but appeared to depend on the content of oxidized groups (carbonyl functionalities), also with a linear correlation. Future work must now clarify the mechanism of this reaction and the influence of other wood constituents, and address the possible potential of e-beaming in the presence of imidazolium ionic liquids for cellulose chemistry.

The directed self-assembly of colloidal nanoparticles (NPs) using external fields guides the formation of sophisticated hierarchical materials but becomes less effective with decreasing particle size. As an alternative, electron-beam-driven assembly offers a potential avenue for targeted nanoscale manipulation, yet remains poorly controlled due to the variety and complexity of beam interaction mechanisms. Here, we investigate the beam−particle interaction of silica NPs pinned to the fluid−vacuum interface of ionic liquid droplets. In these experiments, scanning electron microscopy of the droplet surface resolves NP trajectories over space and time while simultaneously driving their reorganization. With this platform, we demonstrate the ability to direct particle transport and create transient, reversible colloidal patterns on the droplet surface. By tuning the beam voltage, we achieve precise control over both the strength and sign of the beam−particle interaction, with low voltages repelling particles and high voltages attracting them. This response stems from the formation of well-defined solvent flow fields generated from trace radiolysis of the ionic liquid, as determined through statistical analysis of single-particle trajectories under varying solvent composition. Altogether, electron-beam-guided assembly introduces a versatile strategy for nanoscale colloidal manipulation, offering new possibilities for the design of dynamic, reconfigurable systems with applications in adaptive photonics and catalysis.
