The effect of the Hofmeister series on the deswelling isotherms of poly(N-isopropylacrylamide) and poly(N,N-diethylacrylamide)

The influence of Na2SO4, NaCl, NaBr, and NaI was studied on the deswelling isotherms of thin films of photo-crosslinked poly(N-isopropylacrylamide) and poly(N,N-diethylacrylamide) to help elucidate the mechanisms by which ions of the Hofmeister series affect the solubility of neutral, amide-based polymers. The films were characterized with both ellipsometry and FTIR to determine both water content and the frequency of the CO, N-H, and CH3 vibrations associated with the polymers. When compared at the same water content, the frequency of the N-H bend in poly(NIPAAm) red-shifts in the order I- > Cl- > Br- > SO42-. The red-shift is consistent with disrupted hydrogen bonding of the N-H moiety due to an ion-dipole attraction. The CO stretch on the other hand is insensitive to the ion, suggesting that the ion pairs primarily with the partially positive end of the HN-CO dipole. For poly(DEAAm), which lacks an N-H moiety, the CO stretch is now sensitive to the ion, with the trend following the order of the ion in the Hofmeister series. Both of these findings signify that I- > Cl- > Br- > SO42- with respect to the strength of the ion-dipole interaction. Moreover, the ion-dipole interaction is stronger in poly(NIPAAm) than poly(DEAAm), suggesting that the specificity of the Hofmeister ions arises from the effect of vicinal groups on the amide dipole.

Polymer Zwitterions for Stabilization of CsPbBr3 Perovskite Nanoparticles and Nanocomposite Films

Functional polymers with sulfobetaine or phosphorylcholine zwitterions as pendent groups are demonstrated as both ligands and host matrices for CsPbBr3 perovskite nanoparticles (PNPs). These polymers produce nanocomposite films with excellent NP dispersion, optical transparency, and impressive resistance to NP degradation upon exposure to water. Multidentate interactions of the zwitterion-containing copolymers with the PNPs induce dispersed or weakly aggregated nanocomposite morphologies, depending on the extent of zwitterionic functionality in the polymer. Incorporating additional functionality into the polymers, such as benzophenone pendent groups, yields lithographically patternable films, while time-resolved photoluminescence measurements provide insight into the electronic impact of PNPs in zwitterionic polymer matrices.

Swelling behavior of thin, surface-attached polymer networks

The swelling behavior of thin, surface-attached cross-linked dimethylacrylamide (DMAAm) films in contact with water has been characterized with multiple-angle nulling ellipsometry and compared to the swelling of nonattached, bulk DMAAm networks. The polymer networks are fabricated by cross-linking thin films of statistical copolymers composed of DMAAm and a photoreactive benzophenone derivative monomer. Covalent attachment of the film to the surface is achieved by means of a benzophenone-based silane monolayer. UV illumination simultaneously cross-links and chemically links the layer and chemically links the layer to the surface, forming stable networks that do not delaminate upon swelling. It is observed that the surface-attached networks swell less than the nonattached, bulk networks at the same cross-link density; however, the swelling of surface-attached networks is larger than that suggested by simple geometric considerations for swelling in one dimension. The results are in qualitative agreement with Flory-Rehner theory extended to one-dimensional swelling.
