Stimulus Response

High-density polymer brushes were grown from the silicon surface by atom transfer radical polymerization of Poly(N-isopropylacrylamide) (PNIPA) at different polymerization conditions. PNIPA brushes were prepared using Copper (I) Chloride/tris(2-(dimetylamino)ethyl)amine (Me6TREN) as a catalytic system in DMSO at 20°C. Free polymer formed during the brush formation was characterized by gel permeation chromatography. The grafting densities up to 0.52 chains/nm2 were obtained. The layer thickness of polymer brush increases with the increase of conversion of the monomer conversion as well as polymerization time. Atomic force microscopy and air bubble contact angle under pH solution were employed to study the surface morphology, reversible conformational changes of and stimulus-response behavior. PNIPA brushes exhibited a different nanomorphology after treatment with different pH solution. It also revealed a unique reversible wetting behavior with pH. The reversible properties of the PNIPA brushes can be used to regulate the adsorption of the sulfonated PS nanoparticles.

Stimuli Responsive Polymer

AbstractThis review article summarizes the progress of research in the field of polymer brush/metal nanoparticle hybrid materials. We will discuss the mutual influence of polymer brush matrix and particles. Self-assembly of particles within polymer brushes, and ways to control the loading and location of nanoparticles inside polymer brushes will be described, as well as the possibility to use the brush templates as nanoreactors to generate metal nanoparticles. The combination of stimuli-responsive polymer brushes and nanoparticles exhibiting surface plasmon resonance, such as gold or silver, enables the design of optical sensors based on reversible variations of the brush conformation. Sensing devices are capable of detecting a variety of extrinsic variations in their surrounding enviroments. The progress in the development of such optical sensors using brush/particle hybrids will be discussed in more detail.
