Ledesma-Motolinía, Mónica Braibanti, Marco Rojas-Ochoa, Luis F. Haro-Pérez, Catalina 2015-10-05 The structural and optical properties of thermosensitive particles, nanogels, are studied by light scattering and refractometry as a function of temperature. Nanogels are composed of poly- N-Isopropopylacrylamide, a polymer that shrinks at temperatures higher than its lower critical solution temperature, 33 °C. The internal nanogel structure obtained by light scattering is well modeled by assuming a constant radial mass density profile convoluted with a Gaussian function. Moreover, we introduce a simple method that allows us to describe the measured temperature-dependent index of refraction of these complex nanoparticles by using their structural information, core dimension and external radius. application/pdf https://folia.unifr.ch/global/documents/304780 https://folia.unifr.ch/documents/304780/files/bra_ibi.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1016/j.colsurfa.2015.07.020 info:eu-repo/semantics/openAccess License undefined Colloids and Surfaces A: Physicochemical and Engineering Aspects. - 2015, vol. 482, p. 724–727 Poly NIPAM nanogels Particle form factor Refractive index Light scattering info:eu-repo/classification/udc/53 Interplay between internal structure and optical properties of thermosensitive nanogels http://purl.org/coar/resource_type/c_6501
