Delamination and out-of-plane deformation in drying colloidal suspensions
Puntos clave
This research investigates how drying affects the structural integrity of colloidal suspensions on surfaces.
Examined the formation of solid deposits from colloidal suspensions on substrates during evaporation.
Analyzed pore pressure gradients within the deposits as water evaporates.
Observed the movement and delamination phenomena occurring in the solidified structure.
Identified significant delamination occurring as pore pressure varies during drying.
Observed out-of-plane deformation correlated with evaporation rates and suspension characteristics.
Noted the formation of stresses that affect the structural stability of the deposit.
Resumen
A drop of a colloidal suspension placed on a substrate forms a solid particle deposit as it dries. As water evaporates, large gradients in pore pressure inside the porous deposit...
