Design and Preparation of Nanostructured Tio2 Materials by Using Supercritical Co2 Silanization, and Post-functionalization
The present work presents the latest advances for the modification of TiO2 surfaces by their functionalization with complex organic molecules through a scCO2 strategy. Two strategies were followed: the first strategy involved the deposition under anhydrous conditions onto the TiO2 surface of laboratory prepared silane containing nitro-phenyl and nitro-formyl groups, leading to the products desi...
متن کاملFunctional Nanostructured Molecular Materials
The Electrochemical Society Interface • Fall 2001 here has been tremendous recent interest in the design and assembly of porous nanostructured materials.1 Synthetic approaches range from coordination-polymer formation to surfactant-templated alumino-silicate growth to semiconductor nanoparticle aggregation, while functions include chemical catalysis, chemical sensing, energy storage, and energy...
متن کاملPreparation of Nanostructured Membranes by Reactive Depositions from Supercritical Fluids NSF Functional Nanostructures Grant 9811088
Introduction: The fabrication of structured materials for applications in optics, microelectronics, sensors, membranes, and catalysis often requires the deposition of metal or metal oxides onto or within supports or templates. Due to various fundamental constraints of deposition reactions in vapor and liquid media, current metallization techniques are typically impractical for supports with com...
متن کاملSupercritical Fluids as Processing Media for Nanostructured Devices
Supercritical fluids including carbon dioxide offer a combination of properties that are uniquely suited for device fabrication at the nanoscale. Liquid-like densities, favorable transport properties, and the absence of surface tension enable solution-based processing in an environment that behaves much like a gas.These characteristics provide a means for extending “top-down” processing methods...
متن کاملNew Functional Materials from Nanostructured Polymers
The dispersion of nanoscale particles or domains in a polymer matrix can provide nonlinear enhancement of the material properties and produce novel nanostructured materials with unique and controllable properties. Our group is currently examining systems that will provide an understanding of how manipulation and control of the structure of polymeric components can be utilized to efficiently and...
