http://www.freepatentsonline.com/7988896.html

This patent from Hon Hai Precision (Foxconn) includes some broad claims for making carbon nanotube/PMMA composite films useful to create capacitor and electromagnetic shielding structures. Claim 1 reads:

1. A method of preparing a carbon nanotube/polymer composite material, comprising the steps of:

providing a carbon nanotube-based film and a pre-polymer solution;

placing the carbon nanotube-based film in a container, and pouring the pre-polymer solution in the container to cover the carbon nanotube-based film; and

keeping the carbon nanotube-based film in the container and polymerizing the pre-polymer solution in the container into a polymer.
