Densities, viscosities, surface tension and Ultrasonic speeds of nano composite 5-Methyl Salicylaldehyde (5MS) with Aniline (A) were measured over the entire composition range at temperature 303 K. The adiabatic compressibility ( β), free length (Lf), free volume (Vf) and viscous relaxation time (T) have been calculated from the experimental data. The experimental results have been correlated using Fuzzy Evidence Theory and the results are interpreted on the basis of possible hydrogen bonding between unlike molecules and changes in molecular association equilibria as well as structural effects for these systems. A good agreement among experimental data and the values estimated by theoretical procedure was obtained.

Keywords: 5-MS-A composite material, hydrogen bonding, acoustical and physical parameters, Fuzzy Evidence Theory.
