Effect of nanoparticles in dilute and semi-dilute polymer solutions
Source abstract
Abstract
Polymer solutions of different concentrations along with their temperature dependence in the presence of nanoparticles have been investigated by dynamic light scattering (DLS) technique. Results show the presence of nanoparticle changes the polymer solutions. Both the dilute and semi-dilute polymer solutions have become nearly identical in the presence of nanoparticles at different temperatures, indicating the fact that the behavior of dilute solution at one temperature is nearly identical to the semi-dilute solution at other temperatures in the presence of nanoparticles. This uniqueness of polymer solutions irrespective of their concentrations upon nanoparticle deposition in turn results from the similar relaxation times at different temperatures. This result is obtained from an overlap region having the same relaxation time, where lower temperature correlation data of dilute composite solution overlap with higher temperature correlation data of semi-dilute composite solution. Also, analysis shows that both the composite solutions above and below the room temperature are more homogeneous, keeping their similar trend at other different temperatures.
