It is a very challenging purpose to suspend a nanoparticle in a non-polar medium. In this study, stable nanofluid of nanostructured lamellar boric acid (nBA), which is highly hydrophilic compound (log Kow value is 0.18), to be suspended in non-polar media was successfully prepared. Group Ill base oil; i.e. mineral base oil, was used for modeling non-polar media. According to characterization examinations, optimal nBA nanofluid adding ratio is found to be 3%. Viscosity analyses were held by Brookfield DV2T (R) Viscometer. Friction effect of adding the nBA nanofluid into base oil was characterized by a reciprocating tribometer. Stability of nanofluid suspension in base oil was characterized by Turbisca n Tower (R) instrument. Viscosity of original base oil was decreased by 2.88% at 100 degrees C, friction coefficient value of base oil was decreased by 2.91%; Turbiscan Stability Index (TSI) values of prepared sample was 2.9. These characterizations showed that boric acid, a highly hydrophobic material, suspended in a non-polar environment with the help of a simple route containing auxiliary chemicals and ultrasonic horn.
