Wetting dynamics of polydimethylsiloxane mixtures on a poly(ethylene terephthalate) fiber.

Hypothesis: The wetting dynamics of liquids with identical surface tensions are mostly controlled by their viscosities. We therefore hypothesized that the wetting dynamics of one- (pure liquid) and two-component (mixture) polydimethylsiloxane (PDMS) on a poly(ethylene terephthalate) (PET) fiber with similar surface tensions and viscosities should be controlled by the same underlying physical mechanisms.

Experiments: We studied the capillary rise of PDMS liquids on a PET fiber.
