What Techniques are Used to Measure Viscoelastic Properties?
Several techniques are employed to measure the viscoelastic properties of catalysts, including:
Dynamic Mechanical Analysis (DMA): This technique measures the material's response to oscillatory stress, providing information on storage modulus (elastic behavior) and loss modulus (viscous behavior). Rheometry: Rheometers apply controlled stress or strain to measure the flow and deformation behavior of viscoelastic materials. Atomic Force Microscopy (AFM): AFM can be used to probe the nano-scale viscoelastic properties of catalyst surfaces.
