composites??
I am sure here are many da xia. and I have many questions too. :)
first: how do I select rheometer? I know basically there are two kinds:
capillary and oscillary.
second: I guess that we might can get some different result from testing
filled polymer system from pure polymer system. can you tell me what more
information I can get?
Thanks, | s****u

Wonderlich,Thank you for transfering my post to this club! can you introduce
some your research about this area? I just regret why I did not know this club
before! hehe. anyway, I will be chang ke in this club!
Thanks,
sayyou. | w********h

As to pure polymers, especially monodisperse samples,
you can get a master curve of G' or G",
and in terminal region, G' has a frequency dependence with a power law of 2,
while G" has a power law of 1.
the crossover point of G' and G' reflects the relaxation time, which is one of
the most important parameters for polymers.
Polymers with fillers will show significantly different master curves.
First of all, you will lose the perfect terminal region.
And the plateau modulus will change.
