Outline of Final Research Achievements

Mesoporous siloxane materials have been utilized variety of applications including drag delivery, catalyst, and micro container for chemical processing. The pore characteristics largely affect the performance of the materials. A control of the pore structure by external stimuli has long been one of the central issue of the research of the msoporous materials. In the present project, meso pore structure of mesoporous organo siloxane thin film is controlled by an external mechanical stimulus for attaining switchable gate property. It was found that the meso structure of organosiloxane film largely depends on a degree of deformation of PDMS substrates. The deformation is confirmed as a reversible process. The responsible mesostructured siloxane films are expected for application in drag delivery, dynamic polarizer, responsive catalyst and others.
