What is required for good adhesion?

Good adhesion is generally required whenever a coating is applied to a surface. A clean surface and good wettability are needed for good adhesion.

Nanoparticle coating techniques: Comparison of spin coating and Langmuir-Blodgett deposition

Spin coating is one of the most used thin-film coating technique and for this reason, any new technique is typically compared to it.

What is adhesion?

Adhesion is the attraction between two dissimilar phases. It is commonly divided into mechanical interlocking and physical and chemical bonding.

Enhanced oil recovery - Smart water flooding

Using so-called smart water flooding has increased interest in both sandstone and carbonate reservoirs due to its low cost and minimum impact on the environment.

Wettability determines the adhesion of coatings

Coatings are typically evaluated by methods such as laboratory drawdown. Contact angle measurement can provide a more quantitative approach.

Optimize the level of additives in coating formulation with surface tension measurements

A basic requirement of any coating is that it should form a uniform, defect-free surface. Surface and interfacial tensions play a key role in that.

How to measure contact angle hysteresis and roll-off angle by tilting method?

Contact angle hysteresis is often measured with so-called tilting cradle or plate method. The measurement can be done either manually or automatically.

Enhanced oil recovery: How to measure the wettability of carbonate reservoir core?

Most commonly used methods to study reservoir wettability are Amott-Harvey, USBM, and sessile drop contact angle.
