“… 14 The more the foam formation, the longer the defoaming time and the worse the foam tendency. 15 − 17 Figure 1 shows the foam tendency of four commercial ACs at different temperatures and GA solutions with different volume ratios. As shown in Figure 1 a, the foam tendency of AC-1 is proportional to the ventilation time and inversely proportional to the testing temperature.…”

The foam tendency of aviation coolants (ACs) can be greatly influenced by additives. This study investigates the effect of additives on foam behaviors based on four commercial ACs and glycol aqueous solutions added with different additives. Experimental results show that the foam tendency of ACs can be greatly influenced by surfactants; however, inorganic salts have little effect on foam tendency. The volume of generated foam reaches up to 350 mL after ventilation for an AC with a surfactant, much larger than 40 mL of an AC with an inorganic salt. The surface tension of ACs reduces with the addition of surfactants, the lower the surface tension, the more the foam formation. Furthermore, the presence of arranged surfactants at the gas–solution interface can increase the intermolecular forces and enhance the liquid and viscosity of film elasticity, thereby enhancing the foam stability. Besides, the surfactants would weaken the gas diffusion of foams and affect the defoaming property of ACs accordingly.

Preparation of coal tar pitch-based carbon foams has been attempted through a polymer-assisted sacrificial template method. The polymer helped in ensuring maximum impregnation of the foaming precursor in the template. The polymer compatibility factor has been introduced to study the compatibility of different polymers with the precursor. It is a very crucial parameter that can serve as a quantitative and qualitative indicator in the field of polymer-assisted template foaming. The result shows that a precursor particle size of 100 μm or less is suitable for foaming. Polyvinyl alcohol seems to be the most compatible polymer for polymer-assisted template foaming. A lower polymer concentration of 3 wt % is optimum for ensuring the highest compatibility factor of 0.49 and maximum compressive strength of the resultant foam. The final carbon foam obtained by this method exhibited a bulk density of 0.24 g/cc and a compressive strength of 4.23 MPa.
