Dear SpecMat committe,
I would like to request the authorization to bring to the lab a
suspension of carbon nanotube in dichlorobenze.

Multiwall carbon nanotube suspended in dichlorobenzene.
The multiwall are originally from Nanolab, Inc. The dicholorobenze is
from Fisher Scientific. The MSDS are attached.
55 Chapel Street, Newton, MA 02458.

Fair Lawn, NJ 07410
REASON FOR REQUEST
The paper discussing how carbon nanotubes in dicholorbenzene can be
aligned at specified locations is available online at:
I am trying to replicate this protocol to deposit carbon nanotubes on
a Si chip. This is part of my PhD project. The proposed protocol works
only if the nanotubes are suspended in dicholorobenzene.
I plan on dispensing of few ml of the solution on my samples at the
headway2 spin coater . Once the solution has been dispensed, I will
use only equipment from the contimated category:
- PMMA coating at headway2 again
- Exposure at ebeam
- Development at wbebeam
- Metal evaportion at innotec
- Metal lift off at wbsolvent
End of the process flow.
AMOUNT AND FORM
I expect to bring the liquid solution in a 10ml vial. The solution
will be prepared in a chemistry lab.
Amount: 10ml. Form: liquid.
The chemicals will be stored outside SNF.
My process will generate solid waste: the aluminum foil protecting the
headway will be contaminated with dicholorobenzene and carbon
nanotube. Since the dicholorobenzene is a solvent, the waste could be
put in a plastic bag, then in the solvent contaminated bin - just like
when spinning PMMA in anisole.
Please let me know if you have additional questions. Thank you,
