Swelling behavior can be quantified using various techniques:
1. Gravimetric Methods: By measuring the weight of the material before and after swelling, the degree of swelling can be calculated. 2. Dimensional Analysis: Changes in volume or dimensions of the material can be monitored using techniques like optical microscopy or atomic force microscopy (AFM). 3. Spectroscopic Techniques: Methods such as NMR or FTIR can be used to study the interaction between the material and the solvent at a molecular level.
