The new silicone additives reduce the contact angle of water on the silicone elastomer by improving wettability.
There are several simpler wetting/dewetting tests that can be used to characterize substrates for their wettability, including the set of tests found in ASTM D7541.
The wettability of the samples and the control is shown in Figure 2.
Compared to investigations of thermal-hydraulic performance, very rarely have data been reported on the condensate retention on a heat exchanger, and even less has been published addressing the impact of fin wettability.
The increase of surface wettability is connected with the creation of oxygen containing polar groups on the modified polymer surface (7), (10), (11).
Impression detail (Figure 6&7)is influenced by factors such as viscosity, wettability [30-35], handling properties [36-38], and the presence of voids [39-43].
In addition to transparency and wettability, we can fine-tune basically anything that would respond to a change in surface topography, such as adhesive or anti-fouling behavior," Yao said.
Spontaneous imbibition of water is a direct function of the capillary and gravity forces, and depends on the pore system, the wettability (Zhou et al.
Study of the surface wettability of thermally compressed wood is particularly important because the surface wettability plays an important role in the ability of adhesives and paints to wet, flow, penetrate, and cure on the surface of wood.
The surface wettability could further he switched between superhydrophilicity and superhydrophohicity within a time-scale of only seconds by heating above 220[degrees]C and re-spraying the acetone solution of dodecanoic acid in the temperature range of 100-200[degrees]C.
