摘要: The adsorption of a series four poly(N-isopropylacrylamide)-based copolymers composed hydrophilic block methoxy poly(ethylene glycol) (MPEG) with variable length and PNIPAAM fixed size (MPEGn-b-PNIPAAM71) onto flat spherical citrate-coated gold surfaces has been investigated. planar was studied by means the quartz crystal microbalance dissipation monitoring, whereas polymer nanoparticles examined using dynamic light scattering visible spectroscopy. Experiments were performed two different concentrations in bulk solution, namely 0.05 0.0005 wt%. influence MPEG on thickness adsorbed layer nanoparticles, mass recorded at temperatures.
