## Abstract

A method and system for extruding multiple laminated flow streams using microlayer extrusion, and in particular to creating and forming products with electrical properties that are formed from layers and particles with dimensions in the micro to nanometer range.

## Claims

### Claim 1

An extruded thin layer polymer product comprising a wire substrate coated with a polymer extrusion consisting of tens to thousands of annular polymeric layers wherein one or more of said polymeric layers has been filled with electrical conductive particles, wherein the electrical conductive particles form an electrical conducting network in the one or more of polymeric layers through alignment of the conductive filler particles along the direction of the extrusion.

### Claim 2 (depends on 1)

A product according to claim 1 wherein said one or more layers are milli, micro or nano size, wherein said one or more layers contain nanoparticle electrical conducting materials.

### Claim 3 (depends on 2)

A product according to claim 2 wherein said one or more electrical conducting layers are layered between nonconducting layers.

### Claim 4 (depends on 3)

A product according to claim 3 wherein said product is resistant to Electro-Static Discharges (ESD), Electromagnetic Pulse (EMP), High Power Microwave (HPM) attacks, and Electromagnetic Interference (EMI).

### Claim 5 (depends on 2)

A product according to claim 2, wherein at least one layer containing a conducting material is between 20 nm to 100 μm.

### Claim 6 (depends on 2)

A product according to claim 2, wherein at least one layer containing a conducting material is between 20 to 500 nm.

### Claim 7 (depends on 2)

A product according to claim 2, wherein at least one layer containing a conducting material is between 20 to 250 nm.

### Claim 8 (depends on 2)

A product according to claim 2, wherein at least one layer containing a conducting material is between 50 to 250 nm.
