Cellulose Nanocrystals with Tethered Polymer Chains: Chemically Patchy versus Uniform Decoration

Alke Fink, Harm-Anton Klok, Théo Gaston Gérard Lachat, Justin Orazio Zoppe, Alix Vaimiti Marie Dupire

The site-specific surface modification of colloidal substrates, yielding "patchy" nanoparticles, is a rapidly expanding area of research as a result of the new complex structural hierarchies that are becoming accessible to chemists and materials scientists ...

Surface-Initiated Controlled Radical Polymerization: State-of-the-Art, Opportunities, and Challenges in Surface and Interface Engineering with Polymer Brushes

Harm-Anton Klok, Nariye Cavusoglu Ataman, John Moraes, Justin Orazio Zoppe, Piotr Mocny, Jian Wang

The generation of polymer brushes by surface-initiated controlled radical polymerization (SI-CRP) techniques has become a powerful approach to tailor the chemical and physical properties of interfaces and has given rise to great advances in surface and int ...

Effect of Surface Charge on Surface-Initiated Atom Transfer Radical Polymerization from Cellulose Nanocrystals in Aqueous Media

Harm-Anton Klok, Justin Orazio Zoppe, Xingyu Xu

Cellulose nanocrystals (CNCs) with different charge densities were utilized to examine the role of electrostatic interactions on surface-initiated atom transfer radical polymerization (SI-ATRP) in aqueous media. To this end, growth of hydrophilic uncharged ...

Manipulation of cellulose nanocrystal surface sulfate groups toward biomimetic nanostructures in aqueous media

Justin Orazio Zoppe

We report a facile aqueous procedure to create multivalent displays of sulfonated ligands on CNCs for future applications as viral inhibitors. CNCs were decorated with model compounds containing sulfonate groups via reactions of epoxides and isothiocyanate ...
