Formation and application of multivariant assemblies of grafted polymers on flat surfaces
نویسنده
چکیده
Specifically, we will show that polymer assemblies with a gradually increasing grafting density can be utilized to probe the “mushroom”-to-“bush” conformational transition in both neutral polymer brushes as well as weak surface-anchored polyelectrolytes. We will describe a method for generating polymer assemblies with a gradually changing molecular weight of the grafted polymers. A simple extension of the latter approach will facilitate the generation of surface grafted block copolymers with gradually varying compositions.

Formation and properties of multivariant assemblies of surface-tethered diblock and triblock copolymers
We present methodologies for fabricating block copolymer assemblies grafted onto flat solid substrates, where each block of the copolymer possesses a systematic and gradual variation of molecular weight as a function of the position on the substrate. We demonstrate the utility of this technique on two case studies. In the first project, we generate surface-tethered poly[(2-hydroxyethyl methacry...
متن کاملSynthesis of Environmentally Responsive Polymers by Atom Transfer Radical Polymerization: Generation of Reversible Hydrophilic and Hydrophobic Surfaces
Environmentally responsive poly(N-isopropylacrylamide) brushes were grafted from the surface of polymer particles or flat surfaces in order to generate reversible hydrophilic and hydrophobic surfaces. The use of atom transfer radical polymerization was demonstrated for the grafting of polymer brushes as it allows efficient control on the amount of grafted polymer. The polymer particles were gen...

متن کاملSize sorting of protein assemblies using polymeric gradient surfaces.
We report on a novel approach for the size-dependent fractionation of protein assemblies on polymeric surfaces. Using a simple temperature gradient method to generate one-dimensional gradients of grafted poly(ethylene glycol), we fabricated silicon-oxide chips with a gradually changing surface density of kinesin motor molecules. We demonstrate that such a bioactive surface can be used to sort g...
