Improving America's Billion Dollar Industries: From Paper Coatings to Baby Diapers
The DOW Chemical Company funds synchrotron studies in order to characterize new materials and methods for manufacturing. The synchrotron x-ray microscope was used to:
...reveal the substructure of hollow latex particles, which helped DOW researchers determine how to make them work as glossing aids in paper coatings:
Imaging using different x-ray energies reveals the composition of hollow latex particles: styrene at 285.2 eV (green) and acrylate at 288.4 eV (red)
...characterize super-absorbent polymer materials used in baby diapers:
Crosslink density of super-absorbent polymer (SAP) beads treated in two different ways.
In all these examples, DOW used the experimental results to help develop new process technology for manufacturing plants.
...analyze drug particles that had been enhanced for bioavailability:
Imaging using different x-ray energies shows the location of drug vs excipient
