Effect of grafting architecture on the surfactant-like behavior of clay-poly(NiPAAm) nanohybrids

Nano-modified epoxy: the effect of GO-based complex structures on mechanical performance

“…The formation of layered structures is apparently promoted by the amphiphilic surfactant-like structure of the GO-g-ATBN adducts together with their favourable geometry. 37,38 This fact also corresponds to the well-known tendency of different platelet-polymer combinations to form nacre-like arrays. 12 The TEM images also indicate the different morphology of the arrays that depend on the graing geometry and degree, including BA coverage.…”

“…Generally, unlike low-molecular-weight amphiphilic compounds where the self-assembly can be relatively well described by thermodynamic considerations, 35,36 correlations based on the modelling using molecular simulations are mostly done in the case of more "bulky" compounds, such as polymer-graed nanoparticles. 37,38 For instance, simulations of dissipative particle dynamics 38 indicate important effects of the aspect ratio, graed chain length, and number of graed chains on the type of structures formed.…”

Thermoresponsive Brushes Facilitate Effective Reinforcement of Calcium Phosphate Cements

“…PNIPAM brushes can be synthesized using atom transfer radical polymerization (ATRP), which allows for precise control over the molecular weight, grafting density, and thickness of these brushes . In this way, PNIPAM brushes have been grown onto various substrates including cellulose, , clay, graphene, , mesoporous silica, gold, titanium, or even proteins , and nanomotors, thereby allowing for temperature-induced control over the polarity of the coated substrates. Recently, PNIPAM brushes have also been deposited onto nano- and microfibers including lignin and poly­(ethylene terephthalate) fibers − for possible applications such as separation and purification devices .…”
