Dear SpecMat Committee,

This is the request for bringing in my own chemicals into 
cleanroom for spin casting (Au contaminated).
My coral name: xliu9
my PI: Alan Cassell from NASA Ames research center
email: xliu9 at
The chemicals:
Poly(styrene-b-acrylic acid) from polymersource, 
Iron(III) chloride from Sigma-Aldrich 
Toluene from Sigma-Aldrich(
Please see the attached process.
~140mg poly(styrene-b-acrylic acid) is added in 10-15ml 
toluene, then ~20mg FeCl3 is added in the polymer 
solution. Finally, the iron loaded solution is stored into 
a 20 ml vial. All the processes are prepared outside of 
cleanroom. I will bring this vial loaded solution in 
cleanroon for spin casting on Si.For each casted 
substrate, I only need 20ul of the solution.
I will not store the solution in SNF.

Thank you
