Analysis of the Structure of Polymer-Inorganic Nanoparticles in Solutions

摘要

A methodical approach to analyzing the structure of hybrid polymer-inorganic particles with covalent bonding between the components has been suggested. Its effectiveness has been demonstrated on the example of modified poly(methyl methacrylate) containing covalently bonded zirconium dioxide nanocrystals. The methodological approach is based on the application of viscometry, dynamic light scattering, and absorption spectroscopy for a comparative study of the unmodified polymer and its analogue containing a low weight fraction (about a few hundredths) of hybrid particles. The methodology allows a quantitative estimation of the weight of the polymer component covalently bonded to the inorganic nanoparticle to obtain a fully soluble composite material.
