Powder wettability - how to measure contact angle of powders
Powder wettability plays a significant role in many applications such as coatings, pharmaceuticals, and dispersions. Wettability is typically evaluated through contact angle measurements. Powders, however, add some challenge to these measurements as surface roughness, swelling and liquid penetration into the pores make it difficult to measure the contact angle of powders directly.
