A simple, flexible, and general means for the rapid fabrication of different metal films.
Florida International University (FIU) is pursuing a business partner interested in developing and commercializing Rapid, Room-Temperature Preparation of Highly Conductive Porous Paper-Based Gold Thin Films. FIU inventors have created a new approach for preparing paper-based gold films with excellent conductive and electrochemical properties. A simple, ambient vacuum filtration method is used to rapidly generate gold films without the need for sophisticated instruments or a clean-room environment. The process takes 25 minutes and requires only two steps of filtration with two aqueous solutions. This is the first report on the use of M-SWCNTs as an interface for the direct deposition of AuNPs to immediately form a conductive, three-dimensional gold film on a paper substrate. Easy to use, economical, and environmentally friendly MCE filter paper supports the hybrid nanostructure. The resulting 3D porous gold films demonstrate a high surface area-to-volume ratios, high conductivity, and good mechanical properties. This procedure offers a promising new approach that could be readily generalized for the highly reproducible fabrication of various metal films at ambient conditions, and could also be used as a prelude to transferring the resulting film to other metal or flexible substrates.
We are looking for a business partner to further develop and commercialize the Rapid, Room-Temperature Preparation of Porous Gold Films as a viable alternative to commercially available techniques and to exploit its scientific and business potential as a simple, low-cost method of preparing different non-functionalized or functionalized metal films on various membranes under ambient conditions.
Various conductive materials such as carbon nanotubes can be used as a possible underlay for the deposition of different nanoparticles, including gold, silver, copper, platinum or palladium to form various pure or alternating layers of metal films. Such hybrid films could be used in electrochemical catalysis or electro-optical devices, as well as in reflective, conductive or energy-collecting metallic coatings.
- Porous film offers a superior electrode material for electrocatalytic detection relative to standard flat gold slides
- Generates a larger oxidation current for electroactive molecules such as dopamine and serotonin
- Capable of discriminating the simultaneous presence of both molecules
- MCE filter paper is simple, low-cost, biodegradable, combustible, portable and eco-friendly
