Design and synthesis of core–shell nanocomposites, with a shell of an organic material coating an inorganic nanocrystal core, have been thoroughly investigated due to their prospective applications in many fields, such as catalysis, photonics, electronics, optics, and biomedicine [1, 2, 3, 4, 5, 6]. In the past decade, tremendous research efforts have been devoted to design nanoparticles with the surface coating layer sensitive to external stimuli, such as ionic strength, light, temperature, and pH value [7, 8, 9, 10]. Poly(N-isopropylacrylamide) (PNIPAM) is a well-known thermo-sensitive polymer, exhibiting a lower critical solution temperature (LCST) at about 32 °C in water, and it is one of the most studied smart polymers to modify nanoparticles [11, 12, 13].

Generally, there are two approaches to covalently attach polymer chains to a solid surface. One is a “grafting to” method in which end-functionalized polymers are adsorbed onto the nanoparticles surface after polymerization. The...
