The wetting behaviors of surfaces, such as polymers, hydrogels and metals, may correlate to their ability to bond to adhesives and to other surfaces, as well as to their biocompatibility.
In academia and industry, one widely used method to determine how a liquid wets or adheres to a surface is the sessile drop technique. For instance, the hydrophilicity or hydrophobicity of tooth implant materials has been shown to correlate to their degree of contact with their physiological surroundings, and this method can be used to probe such surface property.
The sessile drop method may also provide information on surface free energy — an important parameter for the surface treatment of material used in medical devices. Medical device developers can use this information to optimize surface treatment and bonding of adhesives on surfaces.
Attendees of this webinar will learn how to:
- Decide which contact-angle measuring technique to use to observe the wetting behavior of your medical device surface.
- Use surface free energy information from contact angles to optimize surface treatment of polymer surfaces used for medical devices.
- Use information on the work of adhesion and interfacial tension between substrate and liquid to optimize adhesion.
