摘      要：An efficient strategy that comprised shorten, chain extension, active groups introducing and homogeneous reaction tactics, was adopted to modify multiwalled carbon nanotubes （MWNTs） with cellulose acetate （CA）. Specially, by utilizing 2,4,6-trichloro- 1,3,5-triazine, a reactive intermediate of the MWNTs （MWNT-triazine） was obtained. Suitable solubility of the MWNT-triazine helps make the homogeneous modification become reality. Detailed characterizations further verified that reaction between chloride atoms in the MWNT-triazine and hydroxyl groups in the CA had contributed to the formation of MWNT-CA conjugates. The novel MWNT-CA consists of carbon （76.3%）, oxygen （18.4%） and nitrogen （5.3%）. With a nanotube-attached CA content of 42.8 wt%, the MWNT-CA is readily soluble in DMSO, NMP, DMF and DMAc. Confirmation of the CA-based modification route might lead to studies aiming for specific sorption and isolation.
