Nanoparticle Stabilization

Responsive non-N-isopropyl acrylamide (non-NIPMA) based core–shell microgels are promising carriers for Pd nanoparticles. The core contains COOH groups to achieve better nanoparticle stabilization. The shell provides control of the catalytic activity.

Spherical Polyelectrolyte Brushes

Nano-sized spherical poly (acrylic acid) (PAA) brushes (SPB) were prepared on the surface of colloidal polystyrene (PS) particles by photo-emulsion polymerization. Atomic force microscopy (AFM) was employed to observe the assembly of SPB on substrates of silicon, gold and mica with various surface properties and to determine the morphological information including particle size, shape and core-shell structure of SPB. We found that the surface polarity, electrostatic interactions between SPB and substrate surface and among SPB and capillary forces during sample drying affect the SPB assembly on substrate surface and their morphology.
