“…These groups should lead to improved interaction between the fibre and the modified matrix. At the very least, the increase in the carbon fibre surface energy should lead to better wettability of the fibres by the non-polar matrix (analogous to a Zisman-Neumann plot [48][49][50]) and, therefore, to a more intimate contact between the phases.…”

“…The mixture density data, apparent molar volumes and excess molar volumes were modeled by the Prigogine-Flory-Patterson (PFP) theory (Prigogine, 1953;Prigogine, 1957;Flory and Orwoll, 1964 a,b ;Flory, 1965;Flory and Abe, 1965;Orwoll and Flory, 1967;Patterson, 1970;Costas and Patterson, 1982). This theory was extensively used to represent excess molar volume and enthalpy for various non-electrolytic liquid mixtures.…”

-Densities and refractive index of binay mixtures of water with four protic ionic liquids, based on ammonium and fatty acids, were measured at 298.15 and 323.15 K, under atmospheric pressure. Apparent and excess molar volumes were obtained by experiments and fitting data to the Redlich-Meyer (RM), RedlichKister (RK) and Prigogine-Flory-Patterson (PFP) equations. The molar volume values were high, suggesting strong ion-solvent interaction. The same interaction also became stronger as the temperature increased. Excess volume values were negative, indicating that packing efficiency ability or attractive interactions occurred in mixtures of ionic liquid + water. The errors (AARD) for the properties in excess were in the range of 1.8% to 7.2%. The PFP error for the apparent volume was in the range of 0.34% to 0.06%, lower than the RM error for the same property, which was in the range of 0.70 to 1.55%. The Gladstone-Dale model was applied to correlate the refractive index of the binary mixture with the density from the values of both pure components.

“…The parameters in eq. [5] have their usual significance as described by Patterson and Delmas (5). The site fraction 02, and the interchange energy parameter X I 2 are obtained on the basis of Flory's relation (13,14) using experimental heat of mixing data.…”

Excess volumes for the binary liquid mixtures of methylisobutylketone with benzene, toluene, chlorobenzene, bromobenzene, and nitrobenzene have been measured at 303.15 and 313.15 K. Excess volumes were negative for all the systems over the entire range of composition and at both the temperatures. The behaviour of VE as a function of composition and temperature was studied. Viscosity data have also been determined for the five systems at 303.15 K. The excess viscosity, A In q, has been calculated and its behaviour as a function of composition was investigated. Introduction As a part of a study on thermodynamic and physical properties of binary liquid mixtures containing aliphatic ketone as one of the components (1 -4), we have reported here excess volumes and viscosities for five binary liquid mixtures. Excess volumes at 303.15 and 3 13.15 K and viscosities at 303.15 K have been measured for methylisobutylketone (MIBK) with benzene, toluene, chlorobenzene, bromobenzene, and nitrobenzene and the molecular interactions in these systems have been investigated. The systems have been selected with a view to study the effect of molecular interactions due to substitution of different groups on the phenyl ring. Further, a literature survey revealed that the two properties have not been studied for the five systems.Prigogine-Patterson-Flory equation of state theory developed on the basis of van der Waals model for energy ( 5 ) has been applied quite successfully to predict excess volumes (6-9). Patterson (7, 8) has stressed the importance of cohesive energy factor in the prediction of VE. We have applied the model for the five systems in which cohesive energy difference between the components changes gradually and VE values are calculated using pure component parameters. Further, the viscosity expressions developed by Bloomfield and Dewan (10) have been used to obtain various contributions to excess viscosity.
