“…Polymerizable surfactants ("surfmers") have been extensively studied for their wide range of applications [39,40]. Since the pioneer work of Sherrington and Hamid [41], who obtained a polysoap rather than polymerized micelles, all the different types of organized phases have been successfully templated by polymerization of various surfmers [42][43][44][45][46][47][48][49][50]. Generally, the polymerizable groups of surfmers are either in the hydrophobic tail or around the polar head.…”

“…In this case, the surfactant serves as both the templating agent and polymer precursor, and the fidelity of the structure templating is significantly better than for the case of nonreactive surfactants. 16,20,21 Compelling examples of functional materials templated from reactive surfactant-based LLC phases and exhibiting promising transport and separation properties have been presented by Gin and co-workers. 22−24 The inverse hexagonal phase (H II ) is a particularly attractive template for functional materials designed for transport applications, as the aqueous cores of the hexagonally packed, cylindrical micelles provide a direct path for ions and molecules to travel.…”

Magnetic-field-directed assembly of lyotropic surfactant mesophases provides a scalable approach for the fabrication of aligned nanoporous polymers by templated polymerization. We develop and characterize a lyotropic liquid crystalline system containing hexagonally packed cylindrical micelles of a polymerizable surfactant in a polymerizable solvent. The system exhibits negative magnetic anisotropy, resulting in the degenerate alignment of cylindrical micelles perpendicular to the magnetic field. Sample rotation during field alignment is used to effectively break this degeneracy and enable the production of uniformly well-aligned mesophases. High-fidelity retentions of the hexagonal structure and alignment were successfully achieved in polymer films produced upon UV exposure of the reactive system. The success of this effort provides a route for the fabrication of aligned nanoporous membranes suitable for highly selective separations, sensing, and templated nanomaterial synthesis.

“…In general, ordered organic materials can be fabricated from organicorganic phases through several routes including phase separation (77), crosslinked lyotropic liquid crystal (LLC) assemblies (78), and hard templating approach by colloidal particles or porous inorganic materials (79). In the phase separation, the pore structures can be formed after etching or degrading one block (A) from the assembled block copolymer (A-B) (77).…”

The design of ordered nonsiliceous mesoporous materials is illustrated based on the surfactant assembly and confinedspace growth. These materials include mesoporous metal oxides, polymers, and carbons with open framework structures, and single-crystal metal, metal oxide and carbon nanoarrays with replicated mesostructures. A generalized "acid-base pair" concept, which self-adjusts the acidity and homogeneity of the inorganic precursor, is proposed to prepare highly ordered mesoporous metal oxides, phosphates and borates, as well as mixed metal oxides and phosphates, with diverse structures. Mesoscopically ordered polymer frameworks with uniformly large pore sizes are derived from the self-assembly from organic templates and organic precursors. Heating these materials transforms them to homologous carbon frameworks. Microwave digested method is an efficient way to enhance the adsorption property of hard silica templates in fabricating ordered nonsiliceous single-crystal nanoarrays. The coordination of organic surfactants with metal ions is also a method to increase the interaction between hard templates and precursors. A one-step impregnation process is used to fabricate ordered silica monoliths with various metal oxide nanocrystals. Improving the interactions between the precursors themselves plays an essential role in replicating ordered mesoporous CdS, SiC and graphitized carbons. Preliminary applications in bone-forming materials, biosensors and electrodes are presented as well.
