摘要：

Following our recent report that it is possible to purify and cut SWNTs by using a saw-edged homogenizer in a monochlorobenzene (MCB) solution of polymethylmethacrylate (PMMA) [Appl. Phys. A 71 (2000) 451], we report here our investigation of the effect of PMMA and MCB on the purification and cutting of SWNTs by thermogravimetric analyses. Our results show that MCB helps the a-C aggregation states to homogenize during the ultrasonic treatment. The PMMA helps to make bundles of SWNTs thinner and accelerates both the cutting and damaging of them. (C) 2001 Elsevier Science B.V. All rights reserved.
