In this article we introduce the MARTINI model of a widely used thermoresponsive polymer, Poly(N-isopropylacrylamide). Importantly, our takes into account polymer's stereoregularity (i.e. tacticity). We highlight effect changing polarity coarse-grained particles comprising polymer on its ability to exhibit temperature-dependent coil-to-globule transition. Our approach allows study behavior poly...
Synthesis and characterization of block copolymer PEG114-b-P4VP58 and PNIPAM93-b-P4VP58. Materials. Polyethylene glycol methyl ether (CH3O-PEG114-OH, Mn ~ 5000 and the polydispersity index, PDI = 1.05) was purchased from Fluka. The monomer 4-vinyl pyridine (Acros Organics, 95%) was purified by vacuum distillation. N-isopropylacrylamide (NIPAM, Acros Organics, 99%) was purified by recrystallizat...
Solubilization of single-walled carbon nanotubes (SWNTs) using noncovalently interacting polymer surfactants in aqueous media has opened up a new vista of SWNTs in biology and medicine. In many potential applications, it is desirable to control the dispersion or aggregation of SWNTs in solvents with external stimuli. Here we report two "smart" SWNT dispersions that respond to temperature and pH...
