The IR show ed that there w as a ertain amoun t of arboxyl on the surfa e of theMWCNT. Rheologi al urve show ed shear torque in reasedw ith theMWCNT ontent in reased. A fter being ompounded in the extruder for five m inutes, the liqu id rystal polymerw as plasti ized su ffi iently. SEM mi ages showed that theMWCNT w as u n iform ly dispersed in them atrix formed a good interfa e w ith the liquid rystal. The tensile test show ed, w ith the in rease ofMW CNT ontent, the modu lus and strength, espe ially the elongation at break of the nano omposites w ere all enhan ed.
