Current Advances of Polymer Composites for Water Treatment ... - Hindawi

A lot of polymer composites were introduced with significant use in water treatment and desalination, including graphene-based composites, carbon-based composites, and clay-based composites [1¨C3]. The polymer composite research was offered due the need for materials with better adsorption and removal characteristics of metal ions, dyes, and other toxic pollutants.

the interaction of waterborne epoxy/dicyandiamide varnishes with metal

The Interaction of Waterborne Epoxy/Dicyandiamide Varnishes with Metal

Abstract. For delayed crosslinking of waterborne epoxy varnishes, dicyandiamide (DICY) is often used as a latent curing agent. While, for amine-based curing agents such as diaminoethane (DAE), chemical interactions with metal oxides are well described, so far, no studies have been performed for DICY and waterborne epoxy varnishes.

Polymer Flocculants | SpringerLink

Definition. Polymer flocculants are water-soluble polymers which can form flocs from individual small particles in a suspension by adsorbing on particles and causing destabilization through bridging or charge neutralization. Polymer flocculants are high molecular weight polymers and have hydrogen-bonding groups and/or ionic groups in the
