Carbon nanotube-based composites and production and applications thereof
Résumé
Title composite material is composed of 0.01-99 wt.% carbon nanotubes, 0-99.9 wt.% polymer (P1) selected from poly(alkyl acrylate), polystyrene, polyvinyl chloride, chlorinated polyvinyl chloride, polyvinylidene fluoride, PMMA, polycarbonates, polyamides, polyesters, polylactones, polyepoxides, polyimines, polyphosphazenes, polyolefins, polybutadienes, polyvinyl acetate, polyvinyl alc., polyketone, and polyurethanes, and a block copolymer having ≥1 block bearing ionic or ionizable functions and a block that is compatible with P1. The compatibilizer prepd. by controlled radical polymn. can control and optimize the interfacial interactions and thus to obtain a stable composite material that can be used in paints, coatings, antistatic materials, thermosets, and thermoplastics. Thus, carbon nanotubes and acrylic acid were dispersed in 1,4-dioxane and polymd. using alkoxyamine as initiator, followed by introducing a second monomer, Me acrylate, to provide a block copolymer.
