“…The supramolecular nature of the gel matrix means it can be easily 35 removed by washing or chemical treatment of the composites to leave an imprint of the gel structure in the polymer. 12,[18][19][20][21] A number of fibrillar, 19,22,23 helical, 21, 24 tubular and macro-porous structures 25 have been imprinted in this way giving rise to porous materials with different pore size, shape and connectivity profiles. 40 Such mesoporous materials have found use in applications such as filtration, storage, catalysis, cell growth, drug delivery and as rewritable materials.…”

Small changes in the molecular structure of the gelator can therefore be used to produce polymeric materials with very different pore shapes, sizes and adsorption characteristics.

“…In a nonpolar environment the molecules will aggregate to minimize the contact between polar and nonpolar regions. According to this concept rod formation was found with tris(alkoxy)benzamides (Beginn et al, 2000c). N-sorbitoyl-3,4,5-tris(alkoxy)benzamides , and crown ether amphiphiles (Beginn et al, 2000a).…”

Porous membranes consisting of poly[2-ethyl-hexyl methacrylate-co-2-diethylaminoethyl methacrylate-cross-1,4-butane diol dimethacrylate] have been prepared by means of the ''gel template leaching'' strategy. Well-defined cylindrical pores with diameters of 6-15 nm have been obtained on applying N-(2-desoxy-sorbityl)-3 0 , 4 0 ,5 0 -tris(dodecyloxy)benzamide as organogelator. Chemical modification of the pores' inner walls with methyl iodide to introduce tetra alkyl ammonium surface groups yielded functional membranes with cationic charged pores. The membranes exhibited anion:cation selectivities depending on the electrolyte concentration. At an ion strength of 1 mM the anion:cation selectivity exceeded values of 100.

“…The aggregates can be later removed to provide nanostructured porous polymeric materials. [43][44][45] The groups of Stupp, [46,47] Kostopoulus, [48] and Korley [49] have reported the toughening of polymers using supramolecular polymers or gels. In addition, the composition of organogelators and polymerizable components used particularly in dental composite to reduce shrinkage and/or to improve mechanical properties have been reported.…”

Supramolecular assembly for superhydrophobic coatings is known for its efficiency and efficacy. However, the mechanical fragility of the coatings limits their use as coating materials. Herein, the combination of (±)‐N,N'‐(trans‐cyclohexane‐1,2‐diyl)‐bis(perfluorooctanamide) CF7, a cyclohexyl diamide‐based low molecular weight gelator, with acrylate polymers for the generation of semi‐transparent omniphobic coatings with significantly enhanced scratch proofness is presented. CF7 has shown the ability to self‐assemble in common solvents into highly entangled fibrous networks with extreme water repellency. The incorporation of covalent polymers, specifically poly(methyl methacrylate) (PMMA) and poly(trifluoroethyl methacrylate) (PTFEMA), helps to fixate the supramolecular CF7 fibers without interfering with the self‐assembled structures. The resulting coatings, namely CF7/PMMA and CF7/PTFEMA, show significantly improved mechanical resistance as well as optical transparency while maintaining excellent water and oil repellency. Furthermore, the homogeneity of the coating in bulk is confirmed by depth profiling of the 3D distribution of the components using time‐of‐flight secondary ion mass spectrometry imaging, which turns out to be an essential technique in order to characterize such materials.
