A method comprising: forming at least one layer of material on at least part of a surface of a first substrate, wherein a first surface of the at least one layer of material is in contact with the first substrate thereby defining an interface; attaching a second substrate to a second surface of the at least one layer of material; forming bubbles at the interface by: forming a solution comprising water and electrolyte, immersing at least the interface in the solution, forming a cathode at the first substrate, at least one layer of material, and second substrate; and disposing an anode in the solution at a location remote from the cathode and near a point of separation of the second substrate and at least one layer of material, from the first substrate; connecting a power source to the cathode and anode, and passing electric current through the solution generated by the power source; and applying mechanical force; whereby the second substrate and the at least one layer of material are jointly separated from the first substrate; wherein the first substrate is provided in the form of a supply roll; the at least one layer of material is formed thereon in a continuous manner; the second substrate is applied to the second surface of the at least one layer of material in a continuous manner characterized in that the applied mechanical force comprises pulling the first substrate in a first direction, and pulling the second substrate along with the at least one layer of material in a second direction, the first and second directions diverging from one another, thereby defining an angle (α) of separation. forming at least one layer of material on at least part of a surface of a first substrate, wherein a first surface of the at least one layer of material is in contact with the first substrate thereby defining an interface; attaching a second substrate to a second surface of the at least one layer of material; forming bubbles at the interface by: forming a solution comprising water and electrolyte, immersing at least the interface in the solution, forming a cathode at the first substrate, at least one layer of material, and second substrate; and disposing an anode in the solution at a location remote from the cathode and near a point of separation of the second substrate and at least one layer of material, from the first substrate; connecting a power source to the cathode and anode, and passing electric current through the solution generated by the power source; and applying mechanical force; whereby the second substrate and the at least one layer of material are jointly separated from the first substrate; wherein the first substrate is provided in the form of a supply roll; the at least one layer of material is formed thereon in a continuous manner; the second substrate is applied to the second surface of the at least one layer of material in a continuous manner characterized in that the applied mechanical force comprises pulling the first substrate in a first direction, and pulling the second substrate along with the at least one layer of material in a second direction, the first and second directions diverging from one another, thereby defining an angle (α) of separation. forming a solution comprising water and electrolyte, immersing at least the interface in the solution, forming a cathode at the first substrate, at least one layer of material, and second substrate; and disposing an anode in the solution at a location remote from the cathode and near a point of separation of the second substrate and at least one layer of material, from the first substrate; connecting a power source to the cathode and anode, and passing electric current through the solution generated by the power source; and applying mechanical force; whereby the second substrate and the at least one layer of material are jointly separated from the first substrate; wherein the first substrate is provided in the form of a supply roll; the at least one layer of material is formed thereon in a continuous manner; the second substrate is applied to the second surface of the at least one layer of material in a continuous manner characterized in that the applied mechanical force comprises pulling the first substrate in a first direction, and pulling the second substrate along with the at least one layer of material in a second direction, the first and second directions diverging from one another, thereby defining an angle (α) of separation.
