Light scattering from polymer solutions
WebOct 5, 2024 · Dynamic light scattering (DLS) Dynamic light scattering experiments were carried out using a 90 Plus Particle Analyzer (Brookhaven Instruments Corporation, USA). Data acquisition parameters were adjusted as: time of analysis, 3 min (average of 3 measurements of 1 min); wavelength, 659 nm; scattering angle, θ = 90°. 3. Results and … WebFor static light scattering experiments, a high-intensity monochromatic light, usually a laser, is launched into a solution containing the macromolecules. One or many detectors are …

WebSep 12, 2024 · The classic example was a light-scattering experiment. In this experiment, a solution of polymer was exposed to a beam of light and the resulting scattered light -- coming from the sample in different directions -- was analyzed to determine the size of the polymer chains in the solution.

WebDilute solutions of electronically active molecules capable of irradiation-driven supramolecular self-assembly are studied by dynamic light scattering. We detect unusual well-defined oscillations in the long time range of the homodyne intensity correlation function for all solutions that were irradiated with white light prior to the measurements. WebLight scattering is a very powerful method for characterizing the structure of polymers and nanoparticles in solution. As part of the Springer Laboratory series, this book provides a simple-to-read and illustrative textbook probing the seemingly very complicated topic of light scattering from polymers and nanoparticles in dilute solution, and goes further to cover …
WebLight-scattering instruments, however, only provide a count rate on an arbitrary scale. This count rate depends on instrument parameters, such as the laser intensity, the quantum efficiency of the detector, the size of the scattering volume, the solid angle of the detector, and the accuracy of the alignment. ...
