For alignment of MWCNT in polymer matrix, an immiscible polymer blend (PS/LDPE) was used as a template. MWCNT composites in PS/LDPE were continuously treated under a constant shear force at 200 ℃ and fixed shear rate of 10 S-1, and MWCNT/PS nanocomposites were directionally elongated. The samples were fractured at liquid nitrogen atmosphere to make a smooth surface by parallel and perpendicular direction of shear force. Additionally, PS was extracted with toluene for several hours. SEM results revealed morphology of MWCNT in the PS/LDPE matrix, indicating alignment of MWCNT parallel to flow direction of polymer matrix. |
