Printable, Anisotropic Nanostructures with Boron Nitride Nanosheets for High Temperature Applications
Abstract
The proposed tasks that will be performer are:Task 1- Solution-based Exfoliation of BN Nanosheets: Chemistry, Ink Properties and Nanosheet Characterization. The aspect ratio in BN nanosheets, defined as the lateral size (L) over the thickness (d), largely affects the percolation threshold of thermally conductive nanostructures and the number of interfaces. The goal for Task 1 is to achieve a large aspect ratio, i.e. large BN nanosheets (1-10 ~m) with a small thickness (less than 5 nm).Task 2- Printing Anisotropic Nanostructures with Aligned BN Nanosheets. Three types of anisotropic structures will be fabricated by printing methods and characterized.Task 3- Characterization and Optimization of Printed, Anistropic Nanostructures with BN Nanosheets Related to High-temperature Applications. We will investigate a range of high-temperature-related properties including thermal conductivity, gas barrier capability, and stability in environments such as corrosion, oxidation, and fire, etc.Task 4- Investigations of Anisotropic Nanostructures with BN Nanosheets toward High Temperature Applications. The goal is to evaluate through close collaborations the feasibility of printed BN nanosheet structures for selected application areas, which include high-power photodiode lasers, high-temperature fiber sensors, microcombustors, and concentrated solar energy conversion, among others.
