摘要: The immersion of the polymeric membrane into a low-molecular-weight liquid medium involves several processes like sorption molecules polymer and dimensional changes caused by mutual interactions between surrounding matrix (swelling). quantitative assessment can be performed monitoring mass during its soaking in (sorption techniques); desorption techniques, i.e., swollen taken out liquid; or volumetric techniques consisting sample.
