Thermosensitive polymer capped plasmonic nanoparticles are novel thermal nanofluids with potential sensing applications. Previous research efforts were focused only on monitoring plasmonic resonance peak shifts caused by aggregation as temperature varied. However, to date, no linear relation between the resonance peak shift and temperature was established. Here, the authors systematically study how plasmonic resonance peak intensity responds to solution temperature using poly(N-isopropylacrylamide)-capped Au nanorods (AuNRs) and nanobipyramids (AuNBPs) under aggregation-free conditions. Results clearly reveal the linear correlation between longitudinal resonance peak intensity and solution temperature for both types of particles. AuNBPs have sharper ends than AuNRs, resulting in greater thermo-sensitivity due to the presence of stronger hot spots. Further anal. and numerical studies demonstrate chem. interface damping effects by surface-capping ligand configurational changes and these theor. results agree well with exptl. observations. This damping-based sensing is reversible with excellent durability, indicating the possibility of potential real-world temperature sensing applications. In the experiment, the researchers used many compounds, for example, Benzyl benzodithioate (cas: 27249-90-7Recommanded Product: 27249-90-7).
Benzyl benzodithioate (cas: 27249-90-7) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Recommanded Product: 27249-90-7
