Dip coating of cylinders with Newtonian fluids
Journal of Colloid and Interface Science, 2022The Landau-Levich-Derjaguin (LLD) theory is widely applied to predict the film thickness in the dip-coating process. However, the theory was designed only for flat plates and thin fibers. Fifty years ago, White and Tallmadge attempted to generalize the LLD theory to thick rods using a numerical solution for a static meniscus and the LLD theory to ...

Dip coated silicon-substituted hydroxyapatite films
Acta Biomaterialia, 2006Silicon-substituted hydroxyapatites have been deposited onto Ti6Al4V substrates by sol-gel technology. The Ca(10)(PO(4))(6-x-y)(SiO(4))(x)(CO(3))(y)(OH)(2-x+y) coatings obtained, with silicon contents up to x=1 (2.8 wt.%), show a homogeneous and crack-free surface composed of particles smaller than 20 nm.

Journal of Non-Crystalline Solids, 1997
Abstract Uniform, transparent indium tin oxide (ITO) films were prepared by dip-coating process using an organic sol composed of indium acetate—diethanolamine—tin octylate-n-propanol mixture and the relationship between their electrical properties, film morphology and dip-coating conditions have been investigated.

Confinement effects in dip coating
Journal of Fluid Mechanics, 2017When a flat plate is withdrawn from a liquid pool, a liquid film is deposited on the plate. This simple process is called dip coating. In the case of vertically upward withdrawal, gravity competes with the surface tension and viscous drag, and the balance between those determine the meniscus shape and hence the film thickness.

Dip-coated thin-film polycarbonate optical waveguides
Applied Optics, 1998We report on our systematic and detailed study of fabrication and characterization of polycarbonate thin-film optical waveguides. Various waveguide properties, such as refractive index, optical loss, waveguide thickness, dispersion as a function of temperature of waveguides and substrates, and the effect of thickness gradient on optical guiding losses,

Dip-coating of aluminium by lead
Journal of Materials Science, 1974A study of the problems connected with the coating of aluminium by molten lead has been made. A theoretical approach shows that lead only wets the aluminium surface if the latter is completely free of oxide. Contact of liquid lead with a “clean” aluminium surface may be effected by using an intermediate layer of molten chlorides as a flux and this ...

Optical monitoring of dip coating
Optical Interference Coatings, 2004Interferometric monitoring is applied to dip coating with Newtonian, non-volatile oils and compared to a simple model. For more complex films, a new polarimetric approach is introduced for direct measurement of a varying refractive index.

Microstructure formation in dip-coated particulate films
Journal of Colloid and Interface Science, 2006The microstructure-dependence of dip-coated particulate thin films on the stability of an aqueous silica sol used as coating bath is studied. Different stability conditions are adjusted in the sol by changing electrolyte concentration and pH value. Care was taken to avoid pronounced aggregation of the particles before the coating process.

Shear‐Thinning effects on dip coating
The Canadian Journal of Chemical Engineering, 1985AbstractThe dip coating operation with shear‐thinning fluids is simulated by the Augmented Lagrangian Method coupled to a finite element discretization. Numerical predictions of coating thickness and meniscus shape compared with experimental data exhibit a very poor agreement.
