Evaluate the influence of surface roughness on wettability

Posted by Matthew Dixon on April 13, 2016

While contact angle (CA) goniometry involving placing a drop of liquid on a surface and measuring the resulting angle has been around for many years, we have only recently developed a system to account for the underlying surface’s micro-scale roughness.

How surface roughness and wettability affects biocompatibility

Posted by Anna Oom on November 24, 2015

Various types of artificial materials are being utilized as implants in all fields of medicine. The surface properties of the implant determine its interactions with the surrounding host tissue. Physicochemical properties of the surface, like wettability and surface roughness, are of prime importance for the optimization of adhesion, spreading and proliferation of cells.

How to study adhesion to wood-plastic composites

Posted by Gunilla Rydén on September 25, 2015


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. Wood-plastic composites (WPCs) are composed of three main ingredients: recycled thermoplastics (such as polyethylene, polypropylene and polyvinyl chloride), wood filler and additives.
