| description | The physical
mechanism of elasticity of liquid surfaces
coated with colloidal particles is proposed. It
is suggested that particles are separated by
water clearings and the capillary interaction
between them is negligible. The case is treated
when the colloidal layer is deformed normally to
its surface. The elasticity arises as an
interfacial effect. The effective Young modulus
of a surface depends on the interfacial tension,
equilibrium contact angle, radius of colloidal
particles, and their surface density. For the
nanometrically scaled particles the line tension
becomes essential and has an influence on the
effective Young modulus. |
