Hi I'd like to ask how you would put a droplet at high viscosity (say 2.5 million times more viscous than water) on a solid surface? The droplet would have to be small (volume less than 10uL, r<1.34mm)..
Thanks!
Thanks!
A highly viscous liquid is a type of fluid that has a thick and sticky consistency, making it resistant to flow. This is due to the strong internal forces between its molecules.
The viscosity of a liquid can be measured using a viscometer, which measures the force required to move a liquid at a certain speed. The unit of measurement for viscosity is called a poise.
The spreading of a liquid drop on a solid surface is affected by various factors such as the surface tension of the liquid, the surface energy of the solid, the shape and size of the liquid drop, and the roughness of the solid surface.
The contact angle of a liquid drop on a solid surface is the angle at which the liquid and solid surfaces meet at the edge of the drop. It is determined by the balance of forces between the surface tension of the liquid, the surface energy of the solid, and the adhesive forces between the two surfaces.
The viscosity of a liquid affects the shape of a drop on a solid surface because it determines how easily the liquid can deform and spread on the surface. A highly viscous liquid will form a more spherical drop, while a less viscous liquid will spread out more on the surface.
