The invention relates to a method for forming a body comprising a particle structure fixated in a matrix material, comprising: Providing an amount of particles, Providing a viscous matrix material to include said particles, Forming a particle structure of at least a portion of said amount of particles, Fixating said viscous matrix so as to fixate said particle structure in the matrix material; characterized by at least a portion of said amount of particles being paramagnetic or ferromagnetic and the formation of the particle structure includes the steps of: First, the particles are provided in a mixture with the viscous matrix material, Second, the viscous mixture is subject to the magnetic field created by a Halbach array so as to form the particle assemblies, Third, the viscous mixture with the particle assemblies is subject to electric field so as to move and/or rotate the particle assemblies in the viscous matrix material. The invention also relates to a body obtained by said method, and to the use of said method in various applications.
A method for forming a particle structure fixated in a matrix material, the particle structure including at least an amount of particles within the matrix material, at least a portion of said amount of particles being at least one of paramagnetic and ferromagnetic, the method comprising:
The method according to any one of the previous claims, wherein the Halbach array is provided by at least one of a refrigerator magnet, a magnetic stripe, a magnetic paper, a magnetic tape and a Halbach magnetic cylinder.
The method according to any one of the previous claims, wherein said particle structure includes at least one pathway of particles extending through the matrix material.
The method according to any one of the previous claims, wherein the amount of particles have a concentration in the matrix material being less than a percolation threshold.
The method according to any one of the previous claims, wherein the amount of particles have a concentration in the viscous matrix material in the a range from 0.1 to 10 vol %.
The method according to any one of the previous claims, wherein the amount of particles include particles comprising at least one of carbon, metal and metal alloys.
The method according to any one of the previous claims, wherein a size of the amount of particles is in a range from 0.5 micrometers to 150 micrometers.
The method according to any one of the previous claims, wherein the electric field is at least one of an AC field and a DC field.
The method according to any one of the previous claims, wherein the matrix material comprises a polymer.
The method according to any one of the previous claims, further comprising a body, the body comprising the particle structure fixated in the matrix material, wherein said body is obtainable by any one of the previous claims.
