Crystallization Quiz
- Armed with only a DSC,
how would you determine the melting temperature of a “perfect crystal”,
noted as T0m.
- You just received a
significant grant and have purchased a new SAXS unit that enables you to
measure the lamellar thickness in films that were isothermally
crystallized at various temperatures. Show the plot that you would use
to determine T0m.
- How would you determine
the morphology of a polymer crystal?
- In the Avrami plot, a
second regime at later crystallization time is observed with a lower
slope. What does this change in slope mean and what causes it? What is
significant about this point in time?
- If you were to produce a
film and wanted to maximize the barrier properties, would you have a
high or low supercooling? Why?
