Abstract: Poly(2-acrylamido-2-methyl-1-propanesulfonic acid) and its copolymer hydrogels are typical polyelectrolyte gels with extremely high swelling capacity that are widely used in industry. It's common to consider these hydrogels as weak materials that are difficult to toughen.…

Abstract: The transition from soluble to colloidal polyelectrolyte complex normally occurs at a critical non-stoichiometric charge ratio. Here, we demonstrated that the conventional batch mixing produces heterogeneous binding and complexation, which could easily mask this soluble-colloidal…

Abstract: Bacterial cellulose nanocrystals (BCNCs) have hydrophilic surfaces due to hydroxyl groups but are water-insoluble. The carboxymethylation improves the solubility of cellulose in polar media through the insertion of carboxymethyl groups. This study aims to evaluate…

Abstract: Abstract Polyelectrolyte-based electrochromic devices containing p -cyanophenylviologen and PVA-borax gel provide two different well-defined colored states (green and red). In this work, the bicolor electrochromic gel was characterized by in situ electron spin resonance (ESR)/ultraviolet–visible–near…
