Ultra-thin zeolite films through simple self-assembled processes

Zeolite thin films are very promising as highly selective separation membra nes, sensors, conductors, and optoelectronic devices, and a wide variety of methods for their preparation have been reported. In this report, the auth ors describe their recent use of self-assembled monolayer techniques to pre pare ultra-thin films of zeolites on silicon wafers. In an aqueous colloida l solution of zeolite particles, an array of the amphiphilic hexanoic acid could induced deposition of a zeolite film through hydrophobic interactions . The method was found to be simpler and less expensive than those previous ly reported.
