Phil Kaufman commented on Phil Kaufman's blog post Carbon Nanotubes Show Promise for Multi-Functional Self-Healing Composites
"We've done some work with a local graphene supplier to use a blend of graphene and nanotubes.  For certain applications there is a synergistic effect by using both materials together. 
So you are doing work on self-healing composites? "

Phil Kaufman replied to M-ro's discussion application of polymer nano-composites in asphalt
"We have done some work adding our stacked-cup carbon nanotubes to cement.  It greatly improves freeze/thaw and mechanical properties.  Haven't done any testing in asphalt but I imagine the results would be similar.   
Best,
