Harmonic amide bond density as a game-changer for deciphering the crosslinking puzzle of polyamide
Nature CommunicationsIt is particularly essential to analyze the complex crosslinked networks within polyamide membranes and their correlation with separation efficiency for the insightful tailoring of desalination membranes. However, using the degree of network crosslinking

Preparation and Characterization of Interfacially Polymerized Polyamide Membrane for Dye Removal
Jurnal Rekayasa Kimia & Lingkungan, 2021 Interfacial polymerization of polyamide was conducted using hydrophobic and hydrophilic membrane support. The effects of monomer concentration were investigated, and the resulting thin-film composite membranes were tested for their performance in dye ...

Advanced Functional Materials, EarlyView.Internally catalyzed siloxane dynamic chemistry is demonstrated resulting from amides covalently linked through alkyl chains to siloxanes. The alkyl length in the siloxane‐containing monomer tunes the network cross‐link density. Siloxane exchange dynamics are faster with increasing cross‐link density, because associative exchange is second order in ...
