Abstract: A method for forming an electromagnetic shielding material includes causing a first portion of a matrix material to enter a target region of a magnetic field, thereby causing first ferromagnetic particles within the first portion of the matrix material to move such that first longitudinal axes of the first ferromagnetic particles become more aligned with the magnetic field. The method also includes curing the first portion of the matrix material within the target region of the magnetic field and thereafter causing a second portion of the matrix material to enter the target region of the magnetic field, thereby causing second ferromagnetic particles within the second portion of the matrix material to move such that second longitudinal axes of the second ferromagnetic particles become more aligned with the magnetic field. The method also includes curing the second portion of the matrix material within the target region of the magnetic field.

Abstract: Examples include a method of forming an electromagnetic shielding material, the method including: applying a magnetic field to a precursor material that includes first ferromagnetic particles embedded within a first portion of a matrix material and second ferromagnetic particles embedded within a second portion of the matrix material, thereby causing the first ferromagnetic particles and the second ferromagnetic particles to move such that longitudinal axes of the first ferromagnetic particles and the second ferromagnetic particles become more aligned with the magnetic field; thereafter forcing the first portion of the matrix material through a filter, thereby moving the first ferromagnetic particles from the first portion of the matrix material into the second portion of the matrix material; and curing the second portion of the matrix material to form the electromagnetic shielding material. Additional examples include an electromagnetic shielding material and an apparatus for forming an electromagnetic shielding material.
