General
Name three requirements for a good lubricious coating
Lubricity, Durability, Adhesion, Biocompatibility, Sterilizability, Manufacturability, Versatility, Thickness
Name two commonly used hydrophilic polymers for lubricious coatings
PVP, PVA, PAA, PEG/PEO
The most common PFAS coating in medical devices
What is PTFE? (Polytetrafluoroethylene)
The study of friction, wear, lubrication
What is Tribology?
The molecule Mussels use to stick to various surfaces
What is Dopamine?
What is the brand name for PTFE?
Teflon
The ratio between friction force and normal force
What is the Coefficient of Friction?
How do hydrophilic coatings provide lubricity?
A water gel layer forms a fluid barrier between the medical device and the tissues eliminating any direct solid-to-solid surface contact during motion.
What makes PFAS an environmental / health concern?
Bioaccumulative and Persistent (Cancer, hormones, liver, development, water and soil contamination)
