In addition, effects of different nanotube functionalization and morphology are characterized via scanning electron microscopy and optical microscopy. To achieve adequate nanotube dispersion in the epoxy...

... mixing method. DMA tests resulted in an increase in storage modulus in the nanophased specimens as CNT loading increased. This is mainly attributed to enhanced CNT dispersion and distribution causing reduced polymer chain movement and increased stiffness. Scanning electron microscopy (SEM) revealed...
