Modification of CNF‐Networks by the Addition of Small Amounts of Well‐Defined Rigid Cationic Nanolatexes

Cellulose nanofibril (CNF)-networks are modified by the addition of small amounts (below 10 wt%) well-defined cationic nanolatexes synthesized through reversible addition–fragmentation chain-transfer-mediated polymerization-induced self-assembly (PISA). Minute nanolatex inclusions lead to increased tensile and shear moduli, indicating that can act as bridging-points between CNFs. At higher content, this stiffening effect is lost, likely due interactions leading plasticization. The influence content size on interparticle distance discussed used a tool understand effects observed in macroscopic properties. Upon annealing, lost softening nanolatexes, core–shell morphology prerequisite for effect. These systems form versatile platform develop fundamental insights into complex condensed colloidal systems, ultimately aid development new sustainable material concepts.
