Does the volume swell ratio relate to the weight gain when a crosslinked polymer is emersed in a solvent? Is it as simple as calculating (delta V) = (delta w)/density?
Polymer volume swelling vs weight gain is the change in the size and weight of a polymer when it comes into contact with a solvent or other liquid. This process is a result of the polymer absorbing the liquid, causing it to swell and gain weight.
Polymer volume swelling vs weight gain is typically measured by immersing the polymer in a solvent and measuring the change in weight and volume over time. The initial and final weight and volume are compared to determine the amount of swelling and weight gain.
There are several factors that can affect polymer volume swelling vs weight gain, including the type of polymer, the type and concentration of solvent, temperature, and the presence of additives or fillers in the polymer.
Polymer volume swelling vs weight gain is important because it can affect the properties and performance of the polymer. For example, swelling can lead to changes in mechanical properties, such as stiffness and strength, and can also affect the permeability and chemical resistance of the polymer.
Polymer volume swelling vs weight gain can be controlled by selecting a polymer with the appropriate properties for a specific application, choosing a solvent that is compatible with the polymer, and adjusting the temperature and concentration of the solvent. Additionally, the use of additives or fillers can also help to control swelling and weight gain in polymers.
