Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization. The effects of the monomer concentration, initiator concentration, reaction time, feeding temperature and reaction temperature on the molecular weight were systematically investigated through single-factor and orthogonal experiments.

Sustainability | Free Full-Text | Effectively Recycling Swine Wastewater by Coagulation–Flocculation of Nonionic Polyacrylamide

Abstract Recycling swine wastewater is an environmental and economic issue for promoting the sustainable development of the pig industry worldwide. The application of a flocculant, non-ionic polyacrylamide (NPAM) for treating the contaminants in wastewater was trialed in this study.

The role of hydration degree of cations and anions on the adsorption of high-molecular-weight nonionic polyacrylamide on glass surfaces

Highlights Adsorption of high-molecular-weight polyacrylamide on glass was probed using AFM in 0.27 M LiCl, KCl, and KNO 3. Adsorbed amount of polymer on glass was in the following order: KCl > LiCl > KNO 3. The adsorption in LiCl and KCl was found to be rapid but with strong adhesion on retraction in KCl. Flat conformation and strong adhesion in KCl is attributed to binding effect of the

molecular dynamics-assisted design of high temperature-resistant polyacrylamide/poloxamer interpenetrating network hydrogels

Molecular Dynamics-Assisted Design of High Temperature-Resistant Polyacrylamide/Poloxamer Interpenetrating Network Hydrogels

Polyacrylamide has promising applications in a wide variety of fields. However, conventional polyacrylamide is prone to hydrolysis and thermal degradation under high temperature conditions, resulting in a decrease in solution viscosity with increasing temperature, which limits its practical effect. Herein, combining molecular dynamics and practical experiments, we explored a facile and fast

The thermal gelation behavior of nonionic polyacrylamide (NPAM) and PEI was investigated, and sodium citrate (NaCit) was selected as a new retarder to prolong the gelation time. The gelation performance of NPAM/PEI gel system can be adjusted by varying NPAM or PEI concentration, and a quadratic model is developed by statistical analysis, which predicts the gelation time of NPAM/PEI gel system.
