Rheological Property Analysis of Hydrogels

Our customer services representatives are available 24 hours a day, from Monday to Sunday.

Rheological properties of hydrogels refer to their flow and deformation, which are concerned with the response of hydrogels to applied stress. This response may be an irreversible viscous flow, reversible elastic deformation, or a combination of the two. Rheological properties can reveal structural differences between different hydrogels such as degree of crosslinking, proximity of the glass transition, structural homogeneity or heterogeneity, and molecular weight. Therefore, rheological property analysis provides basic support for the design of new hydrogels. In addition, a deep understanding of the rheological properties of hydrogels under different temperature, humidity, pH values and other conditions is helpful to further explore their application value.

Alfa Chemistry is committed to providing our customers with professional rheological property analysis services for hydrogels. We believe that the results of our analysis are important for you to further optimize your products.

Analysis Instruments

Alfa Chemistry has a variety of instruments for the rheological property analysis of hydrogels. Among them, the most important instrument is a rotational rheometer, which determines the rheological properties of hydrogels by rotating the disk and measuring torque. In the process, the hydrogel sample needs to be placed on the disk and a certain pressure and shear force applied to simulate its force in actual use. By measuring the rotational speed and torque of the disk, the rheological curve and rheological parameters such as elastic modulus, viscosity modulus, and shear modulus of hydrogels can be obtained or calculated.

More Related Knowledge

Elastic modulus, also known as storage modulus (G'), characterizes the solid-like behavior of hydrogels. Viscous modulus, also known as loss modulus (G''), refers to the heat dissipation generated by the deformation of a hydrogel after the applied force is removed, which characterizes the liquid-like behavior of hydrogels. In general, the curves of G' and G'' with shear stress, time, frequency, etc. can be obtained by a rotational rheometer, which can determine the rheological properties of a hydrogel.
