  Poly (Ethelyne) Oxide/Zirconium dioxide (PEO+xZrO2 ) (x = 0, 5, 10, 25 and 50% wt.) membranes were obtained using 2.5% wt. acetonitrile solution. Room temperature X-Ray diffraction (XRD) showed the presence of a mixture of phases for the whole range of ZrO2 content. Raman measurements (Raman Spectroscopy (RS)) at room temperature revealed the presence of a mixture of vibrational states for the two phases PEO and ZrO2 , respectively. The two techniques XRD and SR confirmed an exponential trend of the increase in the relative volume of ZrO2 on the basis of the content of ZrO2 . The thermal stability of the (PEO+xZrO2 ) membranes was corroborated using DSC measurements. The presence of ZrO2 in the host matrix promoted the reduction of the energy needed to obtain the fusion of the complex polymer and with it an implicit increase of the disorder, coinciding with the two XRD and RS measurements.

  The response to the temperature for a two-Dimensional (2D) spin array of a lattice of 2×2 size Ising-Onsager type was compared with the exact solution and simulation in the formalism of the Monte Carlo simulation. The functions energy, magnetization, heat capacity and susceptibility per spin determined by Monte Carlo simulation and the Metropolis algorithm, showed dispersion of close to 1% when compared to the exact solution and the Onsager model. The finite scaling method for 2D lattices of 2×2, 4×4, 8×8, 16×16, 32×32 and 64×64 size, allowed the calculation of the critical exponents of scaling function magnetization, specific heat capacity and susceptibility. The results show that the scaling functions are independent of lattice size but dependent on temperature and the critical exponent (class of universality).
