摘要:
Elongated, ultra-high conductivity electrical conductors (100) for use in advanced electronic components and vehicles, and methods for producing the same, are disclosed herein. The elongated electrical conductors (100) include a conductor body (110) that defines a longitudinal axis (102). The conductor body (110) includes an isotropically conductive matrix material (120) and a plurality of anisotropically conductive particles (130) interspersed within the isotropically conductive matrix material (120). Each anisotropically conductive particle (130) defines a respective axis (170) of enhanced electrical conductivity that is aligned with the longitudinal axis (102) of the conductor body (110). The methods include providing a bulk matrix-particle composite (98) that includes the isotropically conductive matrix material (120) and the plurality of anisotropically conductive particles (130). The methods further include forming the bulk matrix-particle composite (98) into an elongated electrical conductor (100) and aligning the plurality of anisotropically conductive particles (130) such that the respective axis (170) of enhanced electrical conductivity thereof is at least substantially aligned with the longitudinal axis (102) of the elongated electrical conductor (100).
