摘要:
Continuous ceramic (e.g., silicon carbide) nanofibers (502, 602, 604, 606, 608, 702, 704, 1102, 1104) which are optionally p or n type doped are manufactured by electrospinning a polymeric ceramic precursor to produce fine strands of polymeric ceramic precursor which are then pyrolized. The ceramic nanofibers may be used in a variety of applications not limited to reinforced composite materials (400), thermoelectric generators (600, 700) and high temperature particulate filters (1200).
摘要:
Conductive compositions which are useful as thermally conductive compositions and may also be useful as electrically conductive compositions are provided. The compositions include a conductive particle constituent in combination with a sintering aid which can, for example be a compound of the same metal in the nanometal, an organo-metallic, a metalorganic salt, mercaptan and/or resinate. In some embodiments the conductive particles include a small amount of nanoscale (
摘要:
Underfill materials include inorganic fill materials (e.g., functionalized CNT' s, organo clay, ZnO) that are functionalized reactive with other organic constituents (e.g., organics with epoxy groups, amine groups, or PMDA). The underfill materials also beneficially include polyhedral oligomeric silsesquioxane and/or dendritic siloxane groups that are functionalized with a reactive group (e.g., glycidyl) that reacts with other components of an epoxy system of the underfill.
摘要:
A thermal interface material comprises larger conformable thermally conductive particles, and smaller ceramic thermally conductive particles in a binder. The binder can include thermoplastic (and optionally thermoset) particles and a fugitive liquid which are substantially insoluble in each other. The binder can also include a liquid epoxy. Each of the larger thermally conductive particles is itself a cohesive yet conformable agglomeration of platy particles.

An erasable, shear-thinning writing composition includes a shear-thinning additive and graphite particles dispersed within an aqueous solvent system.
