ABSTRACT:
Mesostructured inorganic-organic materials, in the form of patterned films, monoliths, and fibers, can be prepared with controllable orientational ordering over macroscopic length scales. They are synthesized by controlling solvent removal rates across material interfaces, in conjunction with the rates of surfactant self-assembly and inorganic cross-linking and surface interactions. A method for controlling the rates and directions of solvent removal from a heterogeneous material synthesis mixture that allows the nucleation and directional alignment of self-assembling mesostructures to be controlled during synthesis is disclosed. The aligned mesostructured inorganic-organic materials and mesoporous inorganic or carbon materials can be prepared in the form of patterned films, monoliths, and fibers with controllable orientational ordering. Such materials possess anisotropic structural, mechanical, optical, reaction, or transport properties that can be exploited for numerous applications in opto-electronics, separations, fuel cells, catalysis, MEMS/microfluidics, for example.
