Porous cellulose beads were quaternized with glycidyltrimethylammonium chloride (GTMAC) to explore a potential use of them as an adsorbent for removal humic acid (HA) from aqueous medium. The introduction quaternary ammonium groups was confirmed by FT-IR and XPS analysis. content introduced increased increase in the GTMAC concentration. adsorption capacity decrease initial pH value attained max...

As the living standard improves, disposable sanitary and household paper requires not only softness or easy to fluff in a dry state, but also good antibacterial property. In this study, series of alkyl quaternary ammonium salts (AQAS), kinds antibacterial-debonding agents, were synthesized by using two-step process. The SN2 nucleophilic substitution reaction was designed between triethanolamine...

In this work, we described the combination of photocurable methacrylic monomer and poly(glycerol adipate) (PGA) macromer to form networks that can be further quaternized provide antimicrobial character. Both monomers were synthesized enzymatically. Networks with different content prepared characterized by water contact angle measurements, surface charge, soluble fractions, differential scanning...

This study was conducted to explore a new method for imparting hydrophobicity cellulose nanofiber (CNF) using rosin sizing agent. Anionic CNF made from hardwood bleached kraft pulp by micro-grinding; this anionic then used prepare cationic through quaternization. The hydrophobization of CNFs performed adding the agent and CNFs. zeta-potentials were measured identify adsorption rate in films con...

This article uses 1,4-dibromobutane, hexadecyl primary amine, sodium 3-chloro-2-hydroxypropionate, formaldehyde and formic acid as raw materials to synthesize a new type of concrete air entraining agent (1,4)-bis(cetylmethyl hydroxy-propionic quaternary ammonium salt) butane through the reaction ammonia alkylation quaternization. The characterizes molecular architecture product, surface activit...

Hybrid anion exchange membranes (AEMs) were prepared via chemically functionalizing and crosslinking poly(styrene-b-[ethylene-co-butylene]-b-styrene) (SEBS) copolymers low molecular weight homo-polystyrene (hPS). Via sequential chloromethylation, crosslinking, quaternization, alkalization, a series of hPS/SEBS AEMs obtained with varying content hPS. Systematic structural, morphological, mechani...
