dc.description.abstractEnThe influence of surfactant type and concentration on particle size, formulation yield and stability of the polyurethane (PUR) nanoparticles synthesized by miniemulsion polymerization was investigated. SDS, Tween 80 and Pluronic F68 were employed as surfactants in concentration ranging from 5 to 20% (vs monomer concentration). The surfactant SDS was found not efficient in our system, resulting in a low formulation yield (about 53%), two particle size distributions and zeta potential equal to - 52.3mV. On the other hand, the nonionic surfactants gave monomodal particle size distribution, good yields (> 85%) and zeta potential around to- 24mV. The particles synthesized with Tween 80 or Pluronic F68 were very similar to each other in terms of efficiency, particle size distribution and zeta potential. For instance, the particle diameter slightly decreases from 292nm to 261nm as the amount of Tween 80 surfactant increases from 5 to 20wt.% vs monomer. Moreover, we have observed that a concentration of at least 5wt. % of Tween 80 was necessary to favor particle stability and therefore to avoid aggregation.
