Abstract
We study the water swelling behavior of semi-aromatic crosslinked polyamide ultrathin films in order to characterize the materials properties of the polymer network. Specifically, we utilize X-ray reflectivity and quartz crystal microbalance to measure film thickness increase and mass uptake of the polyamide films due to swelling, respectively. With the aid of the Flory-Rehner theory used to describe the swelling behavior of polymer networks, we are able to extract the Flory interaction parameter and the monomer units between crosslinks by performing the swelling experiments at different levels of hydration.Citation
