International Classification:

B32B 3300

US Classification:

428 86, 428 90, 428 96, 428 97, 361704, 361709

Abstract:

Described is a fibrous thermal interface. The interface comprises flocked thermally conductive fibers embedded in an adhesive in substantially vertical orientation with portions of the fibers extending out of the adhesive. An encapsulant fills spaces between the portions of the fibers that extend out of the adhesive and beneath the free tips of the fibers.

International Classification:

F28F007/00

US Classification:

165185, 165905, 277938, 428364, 428367

Abstract:

A thermal interface includes nanofibrils. The nanofibrils may be attached to a flat base or membrane, or may be attached to the tip portions of larger diameter fibers. The nanofibrils have a diameter of less than about 1 micron, and may advantageously be formed from single walled and/or multi-walled nanotubes.

Abstract:

A fiber velvet comprising nano-size fibers or nanofibrils attached to micro-size fibers is disclosed. Methods of manufacturing the velvet as well as various uses of the velvet are also described. For example, the fiber velvet can be used as a thermal interface or as an adhesive material. The nanofibrils may be attached to a flat base or membrane, or may be attached to the tip portions of the micro-size or larger diameter fibers. Various attributes of the micro-size fibers and of the nano-size fibers, for example, geometry (e. g. size, length, packing density) material type (e. g. carbon, metal, polymer, or ceramic) and properties (e. g. conductivity, modulus, surface energy, dielectric constant, surface roughness) can be selected depending on the desired attributes of the fiber velvet. The nanofibrils have a diameter of less than about 1 micron, and may advantageously be formed from single walled and/or multi-walled carbon nanotubes.
