Dual starch–polyacrylamide polymer system for improved
A starch–PAM system reduces PAM usage for conventional and ballasted flocculation. • With 0.4 mg starch/L, PAM is reduced by 69% (surface water) and 45% (wastewater). • With the dual system (G: 165-200 s −1), floc resistance is not impacted. • Coaddition of a starch-PAM blend solution could be used to reduce the use of PAM.
Single PAM/starch mixture injection and sequential dual polymer injection were compared in order to simplify practical industrial applications. For the tested samples of surface water and wastewater, jar tests showed that the PAM dosage can be significantly reduced (50-70% for surface water) for both conventional and ballasted flocculation if a

In this study, we propose a convenient method for the synthesis of double-network gels by the one-shot radical polymerization for their application to rapid optical tissue clearing. Double-network gels were produced during the radical polymerization of acrylamide (AAm) and sodium styrenesulfonate (SS) in the presence of N,N′-methylenebisacrylamide and sodium divinylbenzenesulfonate as the

Magnetic/pH-sensitive nanocomposite hydrogel based
Objective(s): The main aim of current research was to develop a novel magnetically responsive hydrogel by radical polymerization of carboxymethyl cellulose (CMC) on acryl amide (Am) using N,N'-methylene bis acrylamide (MBA) as a crosslinking agent, potassium persulfate (KPS) as a free radical initiator, and magnetic montmorillonite ( mMT) nanoclay as nano-filler.
Polymer lamination on the aluminum can provide better protection to permeation of water vapor, light, gas, and ultraviolet rays, as well as improved flexibility for the packaging of sophisticated products which is difficult to find from a single metallic packaging system. Polymer lamination on the metal could be favorable for having superior
