 CNTs high surface area results in strong Van Der Waals forces between individual CNTs, causing them to agglomerate together and yielding non-uniform heating properties.In addition, the polymer matrix chosen needs to be carefully chosen such that it can withstand the high temperatures generated and the repetitive thermal cycling required to cure multiple composite components.MWNTs were first used as electrically conductive fillers in metals, at concentrations as high as 83.78 percent by weight (wt%).
