CARBON NANOTUBE-REINFORCED NANOCOMPOSITES

摘要

A combination of MWNTs (herein, MWNTs have more than 2 walls) and DWNTs s ignificantly improves the mechanical properties of polymer nanocomposites. A small amount of DWNTs reinforcment (<1wt.%) significantly improves the f lexural strength of epoxy matrix nanocomposites. A same or similar amount of MWNTs reinforcement significantly improves the flexural modulus (stiffness) of epoxy matrix nanocomposites. Both flexural strength and flexural modulus of the MWNTs and DWNTs-coreinforced epoxy nanocomposites are further improv ed compared with same amount of either DWNTs or MWNTs-reinforced epoxy nanoc omposites. In this epoxy/DWNTs/MWNTs nanocomposite system, SWNTs may also wo rk instead of DWNTs. Besides epoxy, other thermoset polymers may also work.< /SDOAB>
