Why is contact angle important?

In industry, wettability is important for example when manufacturing electronics or when planning how to extract oil from the oil reservoir. In all these applications, knowing the contact angle value gives a strong indication on the performance of the product or a successfulness of the process.

What is contact angle?

Contact angle is easy to understand visually. It is the angle a droplet forms in contact with a solid surface. Thermodynamically, it is a balance between different forces acting on a three-phase contact point where solid, liquid and air meet.

How to study adhesion to wood-plastic composites

Wood-plastic composites are relatively new materials as they started to emerge at the beginning of the 90’s. The most widespread use of WCPs is in outdoor decking but it is also used in railings and siding as well as park benches and indoor furniture.
