Abstract
Methods for preparing nanocomposites with thermal properties modified by powder size below 100 nanometers. Both low-loaded and highly-loaded nanocomposites are included. Nanoscale coated, un-coated, whisker type fillers are taught. Thermal nanocomposite layers may be prepared on substrates.
Claims14
A method for preparing a thermal nanocomposite comprising:
- providing nanofillers with a domain size equal to or less than the mean free path of phonons;
- providing a matrix;
- mixing the nanofillers with the matrix below a loading of 80% by volume thereby producing a thermal nanocomposite;
- and
- wherein the nanocomposite has a thermal conductivity that differs by more than 20% as compared with the thermal conductivity exhibited by a composite material of similar composition with filler particles having a domain size of at least one micron.
