WETTABILITIES OF NYLON

Wettability of four Nylon homologues was investigated. The contact angles for various liquids and the heat of immersion were measured to detect the surface wetting property and the whole wettability of Nylon polymers, respectively, and the comparison of these properties was made for each Nylon. The heat of immersion decreases with the increase in the number of carbon atoms per amide group “N”, but surface wettability does not change systematically.
