摘要: We report the synthesis and solution behavior of photo-, temperature-, pH-, ion-responsive weak polyelectrolyte spherical brushes under different modes confinement. The were prepared by copolymerization N,N-dimethylaminoethyl methacrylate (DMAEMA) 7-(2-methacryloyloxyethoxy)-4-methylcoumarin anchored to silica nanoparticles via surface-initiated atom transfer radical polymerization. photo-cross-linking reversibility nanoparticle-attached coumarin entities are detected UV–visible spectroscopy dynamic light scattering (DLS). cross-linking density poly(DMAEMA) (i.e., PDMAEMA) could be easily controlled alternating irradiation at wavelengths 365 254 nm. Moreover, pH levels ionic strengths is systematically investigated in PDMAEMA brush–polyelectrolyte chains confined only a hard core, cross-linked core points, ...
