Summary
Quantifying changes in rheological properties of fluids undergoing rapid physical change is a non-trivial feat. Certain stimuli (like UV-light, electrical fields, magnetic fields, chemical species interaction, or heat) can initiate rapid changes in rheological properties (viscosity, modulus, etc.). Example systems could include hemostatic agents intended to rapidly coagulate blood, or curing hydrogels for use in medical applications. CPG has the capability to quantify rapid rheological changes of various fluids—even develop non-standard test methods for uncommon requests. This note describes the rheological characterization to quantify soak-up time for a highly absorbent material.
