“…22,29,[33][34][35] To explore the applicability of ARGET ATRP, other cellulosic substrates based on wood fibers were used: dissolving pulp (Dis P), bleached and unbleached Kraft pulp (Ble KP and Unble KP, respectively), and bleached and unbleached CTMP (Ble CTMP and Unble CTMP, respectively). These substrates have a higher degree of noncellulose content which in turn could have an impact on the grafting.…”

For the past decade, the interest in controlled grafting of cellulose has increased immensely. Surface-Initiated Atom Transfer Radical Polymerization (SI-ATRP) has attracted the most interest; however, the sensitivity of this system has so far hindered its utilization in industry. In this study, filter paper, dissolving pulp, bleached and unbleached Kraft-pulp, and chemi-thermomechanical pulp papers were grafted with methyl methacrylate, employing activators regenerated by electron transfer (ARGET) ATRP. The reactions were performed in bulk or with small amounts of aqueous solutions, with no deoxygenation performed. To further demonstrate the robustness of this method towards simpler and more industry-friendly processes, the polymerizations were conducted in glass jars with screw lids. The possibility of recycling the reaction solution was also explored. We believe his thorough study to be an important step towards industrializing the "grafting-from" concept, and the results herein can most likely be extended to other surfaces and monomers.

“…As its anhydroglucopyranose unit contains reactive hydroxyl groups, cellulose has potential use in the design of advanced polymeric materials [6,7]. A variety of approaches has been reported for the modification of cellulose by graft polymerization, provides a significant route that combines the advantages of using natural cellulose and synthetic macromolecules in a wide range of potential applications, such as new materials for drug delivery devices, coatings, sorption agents, and membranes [2,3,8].…”

Abstract. Brush-shaped block copolymer with a dual hydrophilic poly(acrylic acid)-block-poly(oligo(ethylene glycol) acrylate) (PAA-b-POEGA) arms was synthesized for the first time via a simplified electrochemically mediated ATRP (seATRP) under both constant potential electrolysis and constant current electrolysis conditions, utilizing only 30 ppm of catalyst complex. The polymerization conditions were optimized to provide fast reactions while employing low catalyst concentrations and preparation of cellulose-based brush-like copolymers with narrow molecular weight distributions. The results from proton nuclear magnetic resonance ( 1 H NMR) spectral studies support the formation of cellulose-based graft (co)polymers. It is expected that these new polymer brushes may find application as pH-and thermo-sensitive drug delivery systems.

“…31 Several publications report the covalent graing of cellulosic substrates with zwitterionic polymers, most commonly PSBMA, to give hemocompatibility, [32][33][34] applications in sensors 35 and membranes, 36 and generally impart anti-biofouling properties. 37,38 However, all of these reports use polymerisation techniques which require organic solvents, inert atmospheres and the subsequent removal of the catalyst, therefore, it is desirable to nd methods that can be performed under benign aqueous conditions.…”

Biomimetic adsorption of zwitterionic–xyloglucan block copolymers to CNF: towards tailored super-absorbing cellulose materials

et al. 2017

A biomimetic, facile approach to cellulose modification is the utilisation of self-adsorbing, naturally occurring biopolymers, such as the hemicellulose xyloglucan (XG). Herein, XG-block-poly(sulfobetaine methacrylate) (XG-b-PSBMA) zwitterionic block copolymers have been prepared and assessed for their ability to adsorb to cellulose, specifically cellulose nanofibrils (CNF). The polymers were synthesised using reversible addition-fragmentation chain-transfer ( These results highlight the advantage of using an XG block for the biomimetic modification of cellulose to form new cellulose-composite materials such as super-absorbing films.
