“…At high temperatures, when the material has reached a liquid state, capillary forces become dominant, so that information about the surface tension can be extracted from the propagation characteristics of capillary waves. In this regime, the technique is an extension of the technique reported by Yasomoto et al [11,12] and compatible to the results obtained by Ikeda et al [13] and Behroozi et al [14,15].…”

Thermoelastic Model for Impulsive Stimulated Scattering Monitoring the Evolution from Capillary to Rayleigh Type Wave Propagation on the Surface of Viscoelastic Materials Throughout the Glass Transition

In recent decades, the impulsive stimulated scattering (ISS) method, which is based on photothermal and photoacoustic phenomena, has been successfully used to simultaneously investigate the thermal and elastic properties in a four-wave mixing configuration, both in transmission in semitransparent materials and on reflecting surfaces of solids. In this report, an extension of the technique is proposed to study a laser-induced thermoelastic response at the free surface of glass-forming liquids. The employed all-optical configuration allows extraction of information about the acoustic shear modulus in the MHz frequency range, and hence is complementary to the classical ISS configuration in the transmission mode, which is suitable to study the relaxation of the longitudinal acoustic modulus, and to another earlier reported ISS configuration, which is exciting and probing laser-induced thermoelastic phenomena at a liquid-solid interface. A theoretical model is presented and numerically illustrated for the glass transition of glycerol, and experimentally validated for water at room temperature.

“…ISS is a technique that has proven its value for the thermal and elastic characterization of bulk solids [26], thin coatings [27], intermediate layers in multilayered systems [28], bulk fluids [4], fluid-solid interface [6], and the free liquid surface [11][12][13]29]. In the employed ISS scheme shown in Fig.…”

“…As the thermal conductivity of air is small (λ th ) 2.6 × 10 -2 Wm -1 K -1 ), 28 thermal diffusion in the -z direction should not affect significantly the decay of the diffracted intensity at an air/liquid interface, in agreement with the experiment. 47 On the other hand, Terazima and co-workers have observed a strong acceleration of the decay of the thermal phase grating in a liquid in contact with sapphire, 20 the thermal conductivity of the latter being about 3 orders of magnitude larger than that of air.…”

“…46 This result is surprising and differs from the observation reported by Terazima and co-workers that the thermal diffusivity measured at the air/2-propanol and air/1-hexanol interfaces was essentially the same as that in the bulk phases. 47 Moreover, the fit of an exponential function to the measured data has no physical basis. Indeed in solids, thermal diffusivity depth profiles have been shown to depart strongly from exponentiality.…”

Transient grating experiments performed with evanescent fields resulting from total internal reflection at an interface between a polar absorbing solution and an apolar transparent solvent are described. The time evolution of the diffracted intensity was monitored from picosecond to millisecond time scales. The diffracted signal originates essentially from two density phase gratings: one in the absorbing phase induced by thermal expansion and one in the transparent solvent due to electrostriction. A few nanoseconds after excitation, the latter grating is replaced by a thermal grating due to thermal diffusion from the absorbing phase. The speed of sound and the acoustic attenuation measured near the interface are found to be essentially the same as in the bulk solutions. However, after addition of a surfactant in the polar phase, the speed of sound near the interface differs substantially from that in the bulk with the same surfactant concentration. This effect is interpreted in terms of adsorption at the liquid/liquid interface. Other phenomena, which are not observed in bulk experiments, such as acoustic echoes and a fast oscillation of the signal intensity, are also described.

“…Consequently, a very long time (about 30 min) is required to take a single viscosity measurement. In such a low frequency region, various noise sources may overlap with the weak signal from the capillary wave [12,13].…”

A new experimental apparatus, based on the laser-induced capillary wave method involving the use of a pulsed carbon dioxide laser (wavelength 10.6 µm, pulse width 50 ns, power 65 mJ) as a heating source has been developed. Since the present technique is applicable to a wide range of viscosity, this method is applicable to the process in which the viscosity drastically changes within a short period of time. In this method, interfering laser beams heat a liquid surface and generate a capillary wave (the wavelength can be adjusted from 20 to 200 µm) caused by a spatially sinusoidal temperature distribution. The temporal behavior of the capillary wave is detected by a diffracted probe beam (He-Ne laser, 15 mW) at the heated area. The dynamics of the capillary wave provide information regarding thermophysical properties such as viscosity and surface tension. In the present study, several liquid samples spanning the viscosity range from 0.33 to 7080 MPa · s (e.g., acetone, toluene, 1-hexanol, ethylene glycol, JS1000, and JS14000) were investigated at room temperature. The detected signals for several liquid samples exhibiting a wide range of viscosity agree well with theoretical calculations, taking into account the influence of the distribution of surface tension.
