Study of surface roughness effects to liquid contact angle on solid surface

This thesis deals with measurement of liquid contact angle with different surface roughness. The objective of this thesis is to measure the contact angle on different material of solid surfaces and to measure the effect of surface roughness to the shape of liquid drop from above view. Sessile drop m...
