Evaporation-induced self-assembly EISA

The next three chapters (Chapters 9-11) focus on the deposition of nano-structured or microstructured films and entities. Porous oxide thin films are, for example, of great interest due to potential application of these films as low-K dielectrics and in sensors, selective membranes, and photovoltaic applications. One of the key challenges in this area is the problem of controlling, ordering, and combining pore structure over different length scales. Chapter 9 provides an introduction and discussion of evaporation-induced self-assembly (EISA), a method that combines sol-gel synthesis with self-assembly and phase separation to produce films with a tailored pore structure. Chapter 10 describes how nanomaterials can be used as soluble precursors for the preparation of extended... 

As powders are unfavorable with respect to the potential applications in nonlinear optics and in the optical characterization of the composites, ordered mono and bifunctionalized organo-silica thin films were prepared through evaporation-induced self-assembly (EISA) and characterized. 

Brinker et al. developed a simple evaporation-induced self-assembly (EISA) process that allows the rapid production of patterned porous or nanocomposite materials in the form of films, fibers, or spheres. Starting from a homogeneous solution of soluble silica and surfactant below the critical micellar concentration, evaporation of ethanol increased surfactant concentration, driving self-assembly of silica-surfactant micelles and their further organization. By...

Use of Dilute Solutions, The reactivity of the inorganic precursors can also be controlled by using low concentrations to lower the reaction rates. Consequent evaporation of solvent results in the formation of organized structure. This approach, introduced by Brinker et al. and termed as evaporation induced self-assembly. (EISA), allows the formation of powders, films, gels, and monoliths. 

Evaporation-Induced Self-Assembly (EISA) The method called evaporation-induced self-assembly (EISA) was introduced by Jeffrey Blinker and coworkers (144) and describes syntheses producing mesostructured materials starting from dilute... 

Alternatively, thin layers of mesoporous silica can be prepared in a single step by a so-called evaporation-induced self-assembly (EISA) procedure [234] the sol solution is deposited onto the electrode surface, and water evaporation occurs concomitantly with micelle formation and condensation of the material the template surfactant is extracted after that complete dryness is reached. A well defined voltammetric response is obtained at the resulting electrode system, due to the species that can diffuse throughout the coating after surfactant removal. 

Route B corresponds to the use of an initial solution containing molecular reactive sol-gel precursors combined with molecular surfactants or amphiphilic block copolymers. It allows generating mesoporous microspheres via evaporation-induced self-assembly (EISA) [15] or evaporation-induced micelle packing...
