Method for manufacturing polymer-CNT composites

摘要

Producing polymer-carbon nanotube composites, comprises: (a) providing carbon nanotube agglomerates having an average agglomerate size of 0.02-6 mm; (b) contacting the carbon nanotube agglomerates with an impregnating material, where the contacting is performed such that the carbon nanotubes agglomerates after contacting exhibit an average agglomerate size of >= 0.02 mm; and (c) incorporating the product obtained in the step (b) into a thermoplastic polymer material or into a reactive resin system with a impregnating material contacted carbon nanotube agglomerates. Producing polymer-carbon nanotube composites, comprises: (a) providing carbon nanotube agglomerates having an average agglomerate size of 0.02-6 mm; (b) contacting the carbon nanotube agglomerates with an impregnating material, where the contacting is performed such that the carbon nanotubes agglomerates (>= 50 wt.%, based on the weight of the carbon nanotubes) after contacting exhibit an average agglomerate size of >= 0.02 mm; and (c) incorporating the product obtained in the step (b) into a thermoplastic polymer material or into a reactive resin system with the impregnating material, which is contacted with carbon nanotube agglomerates. Independent claims are also included for: (1) carbon nanotubes agglomerates (>= 50 wt.%, based on the weight of the carbon nanotubes) contacted with impregnating material exhibit an average agglomerate size of >= 0.02 mm, where the impregnating material includes polyethers, esters, ketones, phosphates, phosphonates, sulfonates, sulfonamine, carbonates, carbamates, amines, amides, silicones, organic compounds with long chain alkyl groups, waxes, glycerides, fats, benzoates, phthalate, adipic acid derivatives, succinic acid derivatives and/or monofunctional epoxides; and (2) carbon nanotubes comprising polymer composite, where the amount of carbon nanotubes is = 50 wt.% and the amount of carbon nanotubes in agglomerates having an average agglomerate size of 0.02-6 mm in the total amount of carbon nanotubes is = 10 wt.%.
