A series of waterborne polyurethane nanocomposites were synthesized using different values (0.3-4.6%) of diol functionalized polyhedral oligomeric silsesquioxane (1,2-propanediol isobutyl POSS). N,N-Bis (2-hydroxyethyl)-2-amino ethane sulfonic acid sodium salt (BES sodium salt) was used as ionic center for preparation of the samples. The prepolymer mixing method was applied for synthesis of compounds. The crucial parameters were temperature, viscosity and rate of stirrer for obtaining the stable dispersions. Here, the IR spectroscopy of neat POSS-diol and a typical synthesized waterborne polyurethane nanocomposite based on 2.4% POSS-diol is investigated
