摘要: Carbon nanotube based nanocomposite membranes have been fabricated through solution casting by embedding multi-walled carbon nanotubes (MWCNTs) within polyetherimide (PEI) polymer host matrix. In order to achieve fine dispersion of and facilitate strong interfacial adhesion with the matrix, were first treated surfactants different charges, namely anionic sodium dodecyl chloride, cationic cetyl trimethyl ammonium chloride non-ionic Triton X100, prior in PEI dope solution. Dispersion MWCNTs N-methyl-2-pyrrolidone solvent showed that agglomeration entanglement greatly reduced upon addition X100. Scanning electron microscopy atomic force examination has evidenced compatibility X100 dispersed matrix which a promising observed at MWCNT-PEI interface. The increase both thermal stability mechanical strength resulting MWCNT/PEI indicated improved interaction between PEI. This study demonstrated role facilitating synergetic effects where composite membrane is anticipated potential application gas separation.
