Title: On the variation of wettability of organic solids in contact with water
Abstract: Abstract For the purpose of assuring the waterproofness of materials used for electrical appliances, experiments have been carried out by the author on the wettability of solids and an interpretation has been made from practical and theoretical points of view. This paper deals with measured changes in the wettability of organic solids in contact with water. Generally, three factors are to be considered which are likely to influence the wettability of a solid surface in contact with water, namely, the penetration of water molecules into the solid (1), the change in orientation of polar groups in the solid surface (2), and the migration of polar groups of impurity molecules from the interior of the solid towards the surface (3). By considering the permeable nature of water molecules in organic polymer substances the variation in wettability of organic solid with time of contact with water is studied from the stand point of the penetration theory.
