Temperature-responsive polymers schematic representation

Figure 5.20 Schematic representation of a responsive polymer brush combined with biological molecules. A change in pH, temperature, or salt concentration leads to a change between a protective state in which an enzyme and a receptor molecule are hidden away deep inside of a brush layer, and an active state in which they are exposed to the solution.

Figure 42.8 Schematic representation of the performance of temperature-responsive nanosystems consisting of PEI/NIPAM grafted onto MSNPs encapsulating iron oxide nanocrystals. The thermoresponsive polymer plays a dual role capping the mesopore entrances to prevent leakage of the drugs hosted Into...

Fig. 18. Schematic representation of the spectral density (or intensity function) for spin couplings in the frame of the three-component analysis of molecular motions in polymers. The dipolar broadening region represented as the hatched section at low fluctuation rates is predominantly responsible for the transverse relaxation rate (compare Eq. 40 and Ref. [2]). Variation of the temperature shifts the components across the fluctuation rate defined by the motional-averaging condition, so that the influence of the individual components changes one by one. Variation of the molecular weight or the polymer concentration likewise shifts the molecular weight or concentration dependent components across the motional averaging fluctuation rate...
