摘要： An electrically conductive, flexible, strain resilient product is produced by mixing metal coated carbon nanotube networks with a liquid polymeric resin to produce a liquid mixture, and the mixture is cured to produce the product. The networks may include welded junctions between nanotubes formed by depositing and melting metal nanoparticles on the nanotubes to form the metal coating. After the mixing step the liquid mixture may be deposited on a flexible substrate in the form of an electrical circuit. The mixing step may further include mixing the composite with a volatile solvent to produce a selected viscosity. Then, a three-dimensional printer may be used to print the product, such as an electrical circuit, on a substrate. The product is cured in an atmosphere that absorbs the solvent. The conductivity of the mixture may be adjusted by adjusting the weight percentage of the metal coated carbon nanotube networks from 50% to 90%, but a preferred range is between 75% and 85%.

摘要： The invention relates to a method of processing a superhard composite material (21) comprising a polycrystalline microstructure and a binder, said method comprising the following steps:

contacting (200) a surface of said superhard composite material (21) with an absorbent material (30), and
applying (300) an electric current to the superhard composite material (21), causing the binder to move from the superhard composite material (21) to the absorbent material (30) so as to create a continuous gradient (221) of binder content within the superhard composite material (21).
