Abstract
Official abstract text for this publication.
An electrically and thermally conductive polymer concrete (made of a polymer and aggregate particles without cement) comprising non-functionalized nanoparticles (e.g. non-functionalized multi-walled carbon nanotubes (NF-MWCNTs), non-functionalized carbon nanofibers, non-functionalized nanoalumina) dispersed therein and methods of making same.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrically conductive polymer concrete made of a polymer, said polymer having dispersed therein non-functionalized nanoparticles comprising non-functionalized multi-walled carbon nanotubes (NF-MWCNTs), non-functionalized carbon nanofibers, and non-functionalized nanoalumina; and said polymer comprising epoxy, methyl methacrylate, styrene or polyester, wherein non-functionalized nanoparticles are added to said polymer at or above a percolation level by weight of said polymer. 2. An electrically conductive polymer concrete made of a polymer, said polymer having dispersed therein non-functionalized nanoparticles comprising non-functionalized multi-walled carbon nanotubes (NF-MWCNTs), non-functionalized carbon nanofibers, and non-functionalized nanoalumina; and said polymer comprising epoxy, methyl methacrylate, styrene or polyester, wherein non-functionalized nanoparticles are added at 2.0-wt % by weight of said polymer, at 3.0-wt % by weight of said polymer or between 2.0-3.0-wt % by weight of said polymer. 3. The electrically conductive polymer concrete of claim 1 wherein said concrete is adapted to receive an electrical current to form a cathodic protection system for corrosion protection by opposing a corrosion current. 4. The electrically conductive polymer concrete of claim 1 wherein said concrete is adapted to receive an electrical current and to send current to a damaged portion of the concrete to self-heal. 5. The electrically conductive polymer concrete of claim 1 wherein said concrete has a strain failure above 2-3%. 6. The electrically conductive polymer concrete of claim 2 wherein the concrete is adapted to receive an electrical current to form a cathodic protection system for corrosion protection by opposing a corrosion current. 7. The electrically conductive polymer concrete of claim 2 wherein the concrete is adapted to receive an electrical current and to send current to a damaged portion of the concrete to self-heal.
