WebContact angle, θ (theta), is a quantitative measure of wetting of a solid by a liquid. The contact angle is geometrically defined as the angle formed by a liquid at the three-phase boundary where a liquid, gas, and solid intersect. There are three different forces acting on this three-phase contact point between solid, liquid and gas, or in some cases solid, … WebWater-swellable (poly-2-hydroxyethylmethacrylate) and water soluble (polyacrylamide) polymers were grafted on polypropylene by a vapor phase photochemical process. 1 On water immersion, the surface hydrogel is formed, which reduces contact angle and improves antistatic properties of grafted material. 1 Corona discharge surface treatment …
