Block copolymers of PDMAEMA and POEGMA as well as Pluronics-type were adsorbed on cellulose surfaces with different anionic charge density and included regenerated cellulose, cellulose nanofibrils (CNF) and TEMPO-oxidized cellulose nanofibrils (TOCNF). The extent and dynamics of adsorption were determined by quartz crystal microbalance (QCM-D) and surface plasmon resonance (SPR). Other tools such as atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS) were used to elucidate features of the adsorbed layer. The role of interfacial water is highlighted ifor the adsorption of the cationic blocks but in all cases, the effect of hydration is observed to have a critical influence in the interface. The observations are highly relevant to properties such as antifouling, friction and surface modification. Some application examples will be discussed.
